HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.

When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors and ground points of each system circuit.Internal wiring for each junction block is also provided for better understanding ofconnection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.

Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

VOLTAGE CHECK

(a) Establish conditions in which voltage is present at the checkpoint.

Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (SW 2 off)

(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.

CONTINUITY AND RESISTANCE CHECK

(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.

(b) Contact the two leads of an ohmmeter to each of the checkpoints.

If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.

(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT

(a) Remove the blown fuse and disconnect all loads of the fuse.

(b) Connect a test light in place of the fuse.

(c) Establish conditions in which the test light comes on.

Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (Connect the

Relay) and SW 2 off (or Disconnect SW 2)

(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.

(e) Find the exact location of the short by lightly shaking theproblem wire along the body.

CAUTION:(a) Do not open the cover or the case of the ECU unless

absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)

(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).

DISCONNECTION OF MALE AND FEMALECONNECTORS

To pull apart the connectors, pull on the connector itself, notthe wire harness.

CAPACITOR (Condenser)A small holding unit for temporarystorage of electrical voltage.

HEADLIGHTSCurrent flow causes a headlightfilament to heat up and emit light. Aheadlight may have either a single(1) filament or a double (2) filament

1. SINGLE FILAMENT

CIGARETTE LIGHTERAn electric resistance heatingelement.

2. DOUBLE FILAMENT

CIRCUIT BREAKERBasically a reusable fuse, a circuitbreaker will heat and open if toomuch current flows through it.Some units automatically reset whencool, others must be manually reset.

HORNAn electric device which sounds aloud audible signal.

DIODEA semiconductor which allowscurrent flow in only one direction.

IGNITION COILConverts low–voltage DC currentinto high–voltage ignition current forfiring the spark plugs.

DIODE, ZENERA diode which allows current flow in onedirection but blocks reverse flow only upto a specific voltage. Above that potential,it passes the excess voltage. This acts asa simple voltage regulator.

LIGHTCurrent flow through a filamentcauses the filament to heat up andemit light.

PHOTODIODEThe photodiode is a semiconductorwhich controls the current flowaccording to the amount of light.

LED (LIGHT EMITTING DIODE)Upon current flow, these diodes emitlight without producing the heat of acomparable light.

DISTRIBUTOR, IIAChannels high–voltage current fromthe ignition coil to the individualspark plugs.

METER, ANALOGCurrent flow activates a magneticcoil which causes a needle to move,thereby providing a relative displayagainst a background calibration.

FUSEA thin metal strip which burns throughwhen too much current flows through it,thereby stopping current flow andprotecting a circuit from damage.

FUSIBLE LINK

METER, DIGITALCurrent flow activates one or manyLED’s, LCD’s, or fluorescentdisplays, which provide a relative ordigital display.

FUEL

FUSIBLE LINKA heavy–gauge wire placed in highamperage circuits which burns through onoverloads, thereby protecting the circuit.The numbers indicate the crosssectionsurface area of the wires.

(for Medium Current Fuse)

(for High Current Fuse or Fusible Link)

MOTORA power unit which convertselectrical energy into mechanicalenergy, especially rotary motion.

RELAYBasically, an electrically operatedswitch which may be normallyclosed (1) or open (2).Current flow through a small coilcreates a magnetic field which eitheropens or closes an attached switch.

1. NORMALLY CLOSED

2. NORMALLY OPEN

SWITCH, MANUALOpens and closescircuits, thereby

SPEAKERAn electromechanical device whichcreates sound waves from currentflow.

RELAY, DOUBLE THROWA relay which passes currentthrough one set of contacts or theother.

Opens and closescircuits, therebystopping (1) orallowing (2) currentflow.

1. NORMALLY OPEN

2. NORMALLY CLOSED

RESISTORAn electrical component with a fixedresistance, placed in a circuit toreduce voltage to a specific value.

SWITCH, DOUBLE THROWA switch which continuously passescurrent through one set of contactsor the other.

RESISTOR, TAPPEDA resistor which supplies two ormore different non adjustableresistance values.

SWITCH, IGNITIONA key operated switch with severalpositions which allows variouscircuits, particularly the primaryignition circuit, to becomeoperational.

RESISTOR, VARIABLE or RHEOSTATA controllable resistor with a variablerate of resistance.Also called a potentiometer orrheostat.

operational.

SENSOR (Thermistor)A resistor which varies its resistancewith temperature.

SWITCH, WIPER PARKAutomatically returns wipers to thestop position when the wiper switchis turned off.

(Reed Switch Type)

SENSOR, SPEEDUses magnetic impulses to openand close a switch to create a signalfor activation of other components.

TRANSISTORA solidstate device typically used asan electronic relay; stops or passescurrent depending on the voltageapplied at ”base”.

SHORT PINUsed to provide an unbrokenconnection within a junction block.

WIRESWires are always drawn asstraight lines on wiringdiagrams.Crossed wires (1) without ablack dot at the junction are

(1) NOT CONNECTED

SOLENOIDAn electromagnetic coil which formsa magnetic field when current flows,to move a plunger, etc.

black dot at the junction arenot joined;crossed wires (2) with ablack dot or octagonal ( )mark at the junction arespliced (joined)connections.

This is the system to change power supply mode by pushing power SW and to start hybrid system by operating power SWand brake pedal simultaneously. It also has function to hold the electrical key in the key slot and not to release the key from itunless the power supply condition and shift range position are met. If there is abnormality in the system, amber portion ofpower SW blinks to warn the driver.

1. ACC ON OperationWhen the electrical key turns on half–inserted SW and deep–inserted SW after inserting in the key slot, transponder keycomputer activates transponder key amplifier incorporated in key slot to identify ID. After the identification, if power SW ispushed without depressing brake pedal, power source control ECU starts. The ECU confirms that the brake pedal is notdepressed from signal of stop light SW and also requests ID code box for ID identification result. If the ID identification isnormal, power source control ECU turns on ACC relay and changes indicator of power SW to green lighting. Inconsequence, power supply is set to ACC ON condition.

2. IG ON OperationIf power SW is pushed without depressing brake pedal when ACC ON, power source control ECU confirms that the brakepedal is not depressed, and then turns on IG1 relay and IG2 relay as well as change indicator of power SW to amberlighting. Power supply is IG ON condition then.

3. Hybrid Start–Up Operation (READY)When the electrical key turns on half–inserted SW and deep–inserted SW after inserting in the key slot, ID code boxactivates transponder key amplifier incorporated in key slot to identify ID. After the identification, if power SW is pushed withdepressing brake pedal, power source control ECU starts. The ECU confirms that the brake pedal is depressed from signalof stop light SW and also requests ID code box for ID identification result. If the ID identification is normal, the ECU turns onACC relay, IG1 relay and IG2 relay, and changes indicator of power SW to amber lighting. Power supply is IG ON conditionthen.After that, power source control ECU sends start–up signal to hybrid vehicle control ECU. Hybrid vehicle control ECU and IDcode box make communication for start–up permission. Hybrid vehicle control ECU controls to start–up hybrid system(READY).At starting up hybrid system, power source control ECU controls to light off indicator of power SW.

4. Power Supply Off Operation∗ When shift range is in P range

If power SW is pushed with power supply at READY condition while the vehicle is stationary, power source control ECUconfirms that shift range is in P range, and then turns off ACC relay, IG1 relay and IG2 relay to put power supply in OFFcondition. The ECU also controls to light off indicator of power SW.If power SW is pushed with power supply at IG ON condition and without depressing brake pedal while the vehicle isstationary, power source control ECU confirms that shift range is in P range, and then turns off ACC relay, IG1 relay andIG2 relay to put power supply in OFF condition. The ECU also controls to light off indicator of power SW.If electrical key is taken off from key slot with power supply at ACC ON condition while the vehicle is stationary, powersource control ECU controls to put power supply in OFF condition automatically, which lights off indicator of power SW.

∗ When shift range is in other than P rangeIf power SW is pushed with power supply at IG ON (Including READY) condition while the vehicle is stationary, parkinglock operation is carried out. After that, power source control ECU confirms that shift range is in P range and then turns offACC relay, IG1 relay and IG2 relay to put power supply in OFF condition. The ECU controls to light off indicator of powerSW.

5. Key Interlock OperationPower source control ECU controls to hold the electrical key in the key slot and not to release the key from it unless thepower supply condition and shift range position are met. Power supply condition and shift range position during the keyinterlock in operation are as follows;∗ At starting–up hybrid system∗ At power supply at IG ON∗ At power supply at ACC ON and shift range at other than P range

6. Emergency Stop Operation of Hybrid SystemIf power SW is kept pushed more than three seconds during driving, hybrid system stops and power supply is changed toACC ON.

7. Power Supply Resuming ControlPower source control ECU always stores power supply condition (OFF, ACC ON, IG ON)When power supply is resumed after shutting off power supply by disconnecting battery terminal, original power supplycondition returns due to control of power source control ECU.

This system controls the following modes in order to achieve the most efficient operations to match the driving conditions.

1. Motor Generator Condition(1) Supply of electrical power from the HV battery to motor generator no.2 provides force to drive the wheels.

(2) While the tires are driven by the engine via the planetary gears, motor generator no.1 activates to supply electricity viathe planetary gears to motor generator no.2 to drive the wheels.

(3) When the vehicle is decelerating, kinetic energy from the wheels is recovered into electrical energy and used torecharge the HV battery by motor generator no.2.

The hybrid vehicle control ECU switches between these modes (1, 2, 1+2, or 3) according to the driving conditions.However, when the state of charge of the HV battery is low, the HV battery is charged by the engine turning motor generatorno.1.

2. Inverter∗ The inverter converts high–voltage direct current of HV battery to three–phase alternating current for driving motor

generator no.1 and motor generator no.2.∗ The activation of the power transistors is controlled by the HV ECU. In addition, the inverter transmits necessary

information for current control, such as the output amperage or voltage, to the HV ECU.∗ Along with motor generator no.1 and motor generator no.2, the inverter is cooled by the exclusive radiator of the coolant

system that is separated from that of the engine.∗ In vehicle collision, circuit breaker sensor installed in the inverter outputs collision signal to stop the system.∗ Boost converter has been adopted in the inverter, which increases rated voltage output from HV battery of DC 201.6V to

DC 500V. After increasing voltage, the inverter converts direct current to alternating current.

3. ConverterThe power source for auxiliary equipment of the vehicle such as the lights, audio system, and the air conditioning system, aswell as the ECUs, is based on a rated voltage of DC 12V system. Because the generator outputs at DC 201.6V, theconverter is used to transform the voltage from rated voltage of DC 201.6V to DC 12V in order to recharge the auxiliarybattery. The converter is installed on the underside of the inverter.

4. HV Battery∗ In Prius, the sealed nickel hydride (Ni–MH) battery has been adopted. This HV battery has high power density, lightweight

and longevity to match characteristics of TOYOTA hybrid system. Because TOYOTA hybrid system controlscharge/discharge to maintain charge/discharge control to maintain SOC (State of charge) at constant level while thevehicle is operating normally, it does not have to rely on the use of external recharges.

∗ The HV battery, battery ECU, system main relay and the cooling fan are put in a signal case which is placed in the luggagecompartment behind the rear seat to make more effective use of vehicle space.

∗ A service plug that shuts off circuit is provided in the middle of the 28 modules (Rated battery capacity = 201.6V). Beforeservicing any portion of the high–voltage circuits, make sure to remove the service plug.Please do not READY ON when you remove the service plug. There is a possibility that battery ECU breaks down.

∗ To ensure the HV battery’s performance, the battery ECU controls the operation of the cooling fan to avoid the heat that isgenerated in the HV battery during charging and discharging.

5. Regenerative System OperationThis system operates the motor as a generator to change the kinetic energy of the vehicle into the electricity when accelpedal is released or foot braking decelerates the vehicle speed, and store the electricity in the battery.

Engine Control

The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof the engine control is given here.

1. Input Signals(1) Engine coolant temp. signal circuit

The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.

(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input toTERMINAL THA of the engine control module as a control signal.

(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input from the heated oxygen sensors to TERMINALOX1B of the engine control module as a control signal.

(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor, and is input into TERMINAL G2 of the engine controlmodule as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is inputinto TERMINAL NE+ of the engine control module.

(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA and VTA2 of the engine control module.

(6) Vehicle speed signal circuitABS speed sensor detects vehicle speed and the speed signal is input from skid control ECU to engine control module.

(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the power SW is pushed on, thevoltage for engine control module starts up power supply which is applied through the EFI M relay, to TERMINAL +B ofthe engine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, andvoltage is constantly applied to TERMINAL +BM.

(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input to TERMINAL VG of the engine control moduleas a control signal.

(9) Water temp. (CHS) signal circuitThe water temp. (CHS) sensor detects the water temp. (CHS) and has a built–in thermistor with a resistance whichvaries according to the water temp. (CHS). The water temp. (CHS) is input into TERMINAL THW2 of the engine controlmodule as a control signal.

(10)Engine knock signal circuitEngine knocking is detected by the knock sensor, and is input into TERMINAL KNK1 of the engine control module as acontrol signal.

(11) Air fuel ratio signal circuitThe air fuel ratio is detected and input into TERMINAL A1A+ of the engine control module as a control signal.

PRIUS (EM01R0U)

2. Control System∗ SFI system

The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.The control signal is sent to the engine control module TERMINALS #10, #20, #30 and #40 to operate the injector (Fuelinjection). The SFI system controls the fuel injection with the engine control module according to the driving conditions.

∗ ESA systemThe ESA system monitors the engine condition through the signals input from each sensors to the engine control module.The best ignition timing is decided according to this data and the data stored in the engine control module. The controlsignal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4, and these signals control the igniter to provide the bestignition timing.

∗ Heater control system of heated oxygen sensorThe heater control system of heated oxygen sensor turns the heater on when the intake air volume is low (Temp. ofexhaust emission is low), and warms up the heated oxygen sensors to improve their detecting performance. The enginecontrol module evaluates the signals from each sensors, and outputs current to TERMINAL HT1B to control the heater.

∗ Heater control system of air fuel ratio sensorThe heater control system of air fuel ratio sensor turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the air fuel ratio sensor to improve detecting performance of the sensor.The engine control module evaluates the signals from each sensor, current is output to TERMINAL HA1A, controlling theheater.

∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FC, and controls the operation of the fuel pump with the C/OPNrelay.

∗ VVT–iVVT–i controls the intake camshaft to optimal valve timing in accordance with the engine condition.

∗ CHS systemEngine control module controls CHS W/P relay to run electric pump to supply heated water stored in CHS tank to enginehead. The electric pump stops when the water reaches certain temperature or certain time goes by. Warming engine headoptimizes combustion conditions at engine start to reduce emission of incomplete combustion gas.

3. Diagnosis SystemWhen there is malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory.The system can be found by reading the code displayed on the malfunction indicator lamp.

4. Fail–Safe SystemWhen malfunction has occurred in any system, there is possibility of engine trouble due to continuous control based on thatsystem. In such a case, the fail–safe system either controls the system using the data (Standard values) recorded in theengine control module memory, or stops the engine.

Daytime Running Light Function (Canada)When power SW is at IG ON position and the vehicle is ready to drive (READY lamp on the display in combination meter ison), releasing parking brake makes signal go into TERMINAL PKB of body ECU. In this condition, when light control SW is atOff/Tail/AUTO position (Headlight is not lit), body ECU sends daytime operation request from TERMINAL DRL/DIM todaytime running light relay. As a result, daytime running light relay duty–operates headlights (Dimmer than regular lighting)

This system adjusts the illuminating angle from changes in the vehicle height and axle distance, based on the information ofthe vehicle height detected by the height sensors installed at the rear of the vehicle and on information of the vehicle speedand acceleration output from the VSC system which operates the reflector with the obtained illuminating angle throughactuators in order to always keep the beam axis constant.If an error occurs in this system, the headlight beam level control warning light in the combination meter lights up andwarning buzzer goes on to warn the driver.

”The light auto turn off system” automatically turns off the taillights or headlights when the driver’s side door is opened, whichprevents the lights from being left on.If the power SW is pushed to OFF from IG ON with the headlights or taillights on, signal is input to the TERMINAL SIG of thebody ECU. If the driver’s side door is opened at that time, the signal from the door courtesy SW front LH is sent to theTERMINAL DCTY of the body ECU. The signal turns off the headlights, front fog lights or taillights.

Interior light operates with control of body ECU.

Illumination ControlLighting function of interior light, overhead J/B, electrical key holderWhen any door is opened, signal is sent from door courtesy SW to body ECU. Interior light, overhead J/B and key slot lighton gradually from unlit condition to fully lit condition within 1.5 seconds if lighting SW of interior light and overhead J/B is setfor door.After that, when all the doors are shut and any one of the door is unlocked, interior light, overhead J/B and key slot are lit upfor about 15 seconds (Timer lighting) and then are lit off gradually.Under conditions that power SW is set at OFF position and all the doors are closed, when any one of the door is unlocked,interior light, overhead J/B and key slot light on gradually from unlit condition to fully lit condition within 1.5 seconds, stay onfor the certain time (Timer lighting) and then light off gradually. If power SW is turned from OFF position to ACC ON or IG ONposition during timer lighting, the timer lighting function is cut off immediately and the light goes off gradually.Even though timer lighting conditions are satisfied when power SW is at ACC ON or IG ON position, the light does not stayon for certain time (For 15 sec.) after lighting, but goes off gradually.All the doors are locked during timer lighting, the timer lighting function is cut off immediately and the light goes off gradually.

With the power SW pushed to IG ON position, the current flows to TERMINAL (B) 2 of the wiper and washer SW, andTERMINAL 2 of the front wiper motor through the WIP fuse.

1. Low Speed PositionWith the wiper and washer SW turned to LO position, the current flows from TERMINAL (B) 2 of the wiper and washer SW toTERMINAL (B) 3 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND, which runs the front wiper motor atlow speed.

2. High Speed PositionWith the wiper and washer SW turned to HI position, the current flows from TERMINAL (B) 2 of the wiper and washer SW toTERMINAL (B) 4 to TERMINAL 3 of the front wiper motor to TERMINAL 4 to GROUND, which runs the front wiper motor athigh speed.

3. INT PositionWith the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL (B) 2 ofthe wiper and washer SW to TERMINAL (A) 2 to GROUND. This activates the intermittent circuit and the current flows fromTERMINAL (B) 2 of the wiper and washer SW to TERMINAL (B) 3 to TERMINAL 5 of the front wiper motor to TERMINAL 4to GROUND and then the wiper operates. Intermittent operation is controlled by a condenser’s charge and dischargefunction in the relay.

4. Washer Interlocking OperationWith the wiper and washer SW pulled to washer position (Washer SW ON position), the current flows from the WSH fuse toTERMINAL 1 of the front washer motor to TERMINAL 2 to TERMINAL (A) 3 of the wiper and washer SW to TERMINAL (A) 2to GROUND and runs the washer motor and the window washer to spray. Simultaneously, current flows from the WIP fuse toTERMINAL (B) 2 of the wiper and washer SW to TERMINAL (B) 3 to TERMINAL 5 of the front wiper motor to TERMINAL 4to GROUND, which activates the wiper.

When the power SW is pushed to IG ON position, the current flows from the WSH fuse to rear washer motor TERMINAL 1,and the current flows from the RR WIP fuse to rear wiper relay TERMINAL 3, and to the rear wiper motor TERMINAL 1respectively.

1. Rear Wiper Normal OperationWhen the power SW is pushed to IG ON position, and the rear wiper and washer SW is turned to HI position, the currentflows from the rear wiper relay TERMINAL 3 to TERMINAL 6 to the rear wiper and washer SW TERMINAL (A) 7 toTERMINAL (A) 2 to GROUND, and turns on the rear wiper relay. As a result, the current flows from the rear wiper relayTERMINAL 3 to TERMINAL 4 to the rear wiper motor TERMINAL 3 to TERMINAL 2 to GROUND, and operates the rearwiper.

2. Rear Wiper Intermittent OperationWhen the power SW is pushed to IG ON position, and the rear wiper and washer SW is turned to LO position, the currentflows from the rear wiper relay TERMINAL 3 to TERMINAL 2 to the rear wiper and washer SW TERMINAL (A) 6 toTERMINAL (A) 2 to GROUND, and the intermittent circuit in the rear wiper relay is controlled to operate the wiperintermittently.

3. Washer OperationWith the power SW is pushed to IG ON position, and the rear wiper and washer SW turned to ON position, when the washeris turned ON (to Wiper HI side), current to TERMINAL 1 of the washer motor flows to TERMINAL 2 of the motor toTERMINAL 5 of the rear wiper and washer SW to TERMINAL 2 to GROUND so that the washer motor rotates and thewindow washer emits water.With the power SW is pushed to IG ON position, and the rear wiper and washer SW turned to OFF position, when thewasher is turned ON (to Wiper OFF side), current flows as above so that the washer motor rotates and the window washeremits water as well as the wiper operates.

Smart key system is a system to enable, without operating the key, to lock/unlock doors, to unlatch luggage compartmentdoor, to start engine (Motor). It owes interactive communication function of electrical key, which makes the vehicle torecognize where the key is. All that driver has to do is to have the key with him or her. If the electrical key runs out of drybattery, the key operates as normal key without the smart key system.

1. Smart Door Unlock FunctionWhen all the doors are locked, oscillator of each door sends signal regularly and forms detecting area outside of passengerroom around 0.7 to 1m from each door handle. After forming the area, driver goes in the area with the electrical key, the keysends ID code signal. Certification ECU receives the signal through electrical key antenna and identifies ID code. Afteridentifying ID code, doors in the area get into unlock stand–by condition. At this time, sensors installed in door handlesactivate. Touching back of door handles unlocks the door locks, lights up hazard lamp and sounds wireless door lock buzzer.If any door is not opened within 30 seconds after unlocking the door lock, the doors lock again.

2. Smart Door Lock FunctionIf driver gets off the vehicle with the electrical key and pushes lock SW of door handles when all doors are locked,certification ECU sends signal to inside and outside of passenger room to identify the electrical key. In case identificationwith inside of the passenger room is NG and that with outside of it is OK, doors lock. Door ajar alarm sounds to tell a door isnot shut properly when lock SW of door handle is pushed with any door opened.

3. Smart Luggage Compartment Door Unlatch FunctionIf the driver stands in front of luggage compartment door with the electrical key and pushes unlock SW of luggagecompartment door, ID code of the electrical key is identified with certification ECU through luggage oscillator (Outer). Afterthe ID code is identified, luggage compartment door is unlocked. To keep pushing luggage compartment door opener SWunlatches luggage compartment door.

4. Smart Ignition (READY) FunctionWhen the driver pushes the power SW with the electrical key with him or her, ID code of the electrical key is identified withcertification ECU by room oscillator in passenger room. After the ID code is identified, hybrid vehicle immobiliser is releasedand electric power is set at ACC ON to enable to start engine. Then pushing the power SW sets power supply at IG ON andanother pushing sets it at OFF. Condition circulates from ACC ON to/from IG ON to/from OFF and to ACC ON. The vehiclegets READY to drive when the driver pushes power SW with applying brake pedal at any power supply condition.

5. Smart Alarm Function∗ If any door is opened and then shut with shift at P range and the power SW at other than OFF position, certification ECU

identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer in combination meteralarms (Once) and wireless door lock buzzer alarms (Three times), and smart warning light in combination meter lights up.If power supply is pushed OFF with power SW or identification of the electrical key with inside of passenger room isconfirmed at the second time, the warning stops.

∗ If all the doors are closed with shift at P range and power SW at other than OFF position, pushing lock SW of door handlestarts certification ECU to identify ID code with inside and outside of passenger room. In case result of identification withinside is NG and that with outside is confirmed, wireless door lock buzzer alarms (For two seconds) and doors do not lock.

∗ If driver’s side door is opened and then shut with shift at other than P range and power SW at other than OFF position,certification ECU identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer incombination meter and wireless door lock buzzer alarm continuously as well as smart warning light in combination meterlights up. Then, if shift is put into P range or the identification with inside is confirmed at the second time, the continuosalarming stops. If the driver turns electric power OFF with power SW or the identification with inside is confirmed at thesecond time, smart warning light goes off.

∗ If other doors than driver’s side door is opened and then shut with shift at other than P range and power SW at other thanOFF position, certification ECU identifies ID code with inside of passenger room twice. In case the identification result isNG, buzzer in combination meter alarms (Once) and wireless door lock buzzer alarms (Three times), and smart warninglight in combination meter lights up. If power supply is pushed OFF with power SW or identification with inside ofpassenger room is confirmed at the second time, the warning stops.

∗ If lock SW of door handle is pushed with all the doors shut and power SW at OFF position, certification ECU identifies IDcode with inside of passenger room twice. In case the identification is confirmed then, wireless door lock buzzer alarms(For two seconds) but doors do not lock.

∗ If power supply is turned OFF with power SW after ”READY to drive” condition are kept for about 20 minutes, certificationECU identifies ID code of the electrical key with inside of passenger room. In case the ECU recognizes code of batteryvoltage decrease, buzzer in combination meter alarms once.

∗ If power SW is pushed ON, certification ECU identifies ID code with inside of passenger room twice. In case theidentification result is NG, buzzer in combination meter alarms once and smart warning light lights up for about fiveseconds. Then, driver’s operation of power SW is cancelled.

When the unlock SW on the transmitter is pressed once, only the driver door will unlocks. When the unlock SW is pressedagain within 3 seconds, all the doors will unlock.

2. Auto Lock FunctionWhen the door is not actually opened within 30 seconds after the door has been unlocked by the unlock SW on thetransmitter, all the doors will automatically lock. If any one of the following conditions is detected, the wireless door lock doesnot function.∗ Any door is opened.∗ The electrical key is inserted in the key slot.∗ Power SW is on

3. Wireless Door Lock Stop FunctionIf any one of the following conditions is detected, the wireless door lock does not function.Lock operation∗ When any door is open (Door courtesy SW on)∗ The electrical key is inserted in the key slot (Unlock warning SW on)∗ Power SW is onUnlock operation∗ Power SW is on∗ The electrical key is inserted in the key slot

4. Visual Confirmation of Lock or UnlockDuring lock operation, when the body ECU receives a lock signal from the door lock detection SW, the turn signal lightflashes once. During unlock operation, when the body ECU receives an unlock signal from the door lock detection SW, theturn signal light flashes twice.

5. Remote Panic OperationPanic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,interior lights light up, and theft alarm and horn sounds and turn signal lights, headlights and taillights flash. Then, any one ofthe button (Transmitter) is pushed once again, interior lights turn off, sounding and flashing will stop. Panic will not functionwhen power SW is on.

6. Repeat FunctionIf the lock detection signal is not received in response to the output signal after the body ECU has output the lock signal, thelock signal is output again.

7. Illuminated Entry FunctionWhen the body ECU detects the unlock state after the unlock operation has been made, it lights up the key slot, overheadJ/B and interior light for approx. 15 sec. If all the doors are locked during this operation, lighting is cancelled and the lightsimmediately fade out.

PRIUS (EM01R0U)


Under this system, operating signal of shift lever is sent to hybrid vehicle control ECU to control hybrid motor, which changesshift ranges (R, N, D, B) electrically. When shift is put in P range, transmission control ECU receives operating signal fromhybrid vehicle control ECU and activates parking lock electrically.

1. Shift Range Change FunctionGear can be shifted to any shift range under condition when vehicle can drive except when reject function is in operation.When vehicle cannot drive with power SW at IG ON position, gear can be shifted only to P and N range.When vehicle cannot drive with power SW at ACC ON position, gear can be shifted only to P range.When power SW is at OFF position, gear cannot be shifted to any range.When main SW is operated at vehicle stop after starting hybrid system, gear is automatically changed to P range from anyother gear range and turns off power supply.

2. Reject FunctionChanging gear may not effect to change range under certain vehicle condition. Under such condition, warning buzzer ofcombination meter sounds to show the rejection and call for driver’s attention. Followings are shift operations and shift rangeconditions under which reject function is activated.∗ When gear is shifted from P range to other range without applying brake pedal, gear stays in P range.∗ Main SW cannot put gear in P range during driving but changes to N range.∗ Shift change to forward or backward during driving changes gear to N range.∗ When gear is changed from other range than D range to B range, gear is changed to N range automatically.

3. Combination Meter IndicationThe combination meter shows present shift range position. Other shift range positions than D or B range are not shown inlighting in the combination meter. This is to avoid unnecessary shifting operation to B range from other shift position except Drange.

4. Operation of Parking LockOperation signal from/to P range is sent from main SW or power SW to transmission control ECU through hybrid vehiclecontrol ECU. At that time the transmission control ECU operates P CON MTR relay, activates parking lock actuator withappropriate control of electric current, and lights up main SW when shift is at P range. If the system has abnormality onparking lock operation, it tells the system abnormality to the driver by lighting up master warning light on combination meter,displaying warning of the system abnormality on the multi–display, and blinking indicator light of main SW.

5. Operation at Electric Power OFFUnder electric power OFF, transmission control ECU receives signal from power source control ECU bymulti–communication, and sends shift range position information to hybrid vehicle control ECU. The hybrid vehicle controlECU sends signal to power source control ECU to tell whether it is right or wrong condition to turn off electric power.Accepted conditions for electric power OFF are as follows;∗ When hybrid vehicle control ECU is not sending request signal for parking lock release with shift range in P range position.∗ With shift range is at other range than P range, when hybrid vehicle control ECU is outputting signal that hybrid system is

not running or request signal for parking lock.∗ When there is abnormal motor’s not running condition with paring lock in operation, and hybrid system is not running and

parking brake is being applied.

Cruise Control

Cruise control is the speed control device, which can set desired speed by just operating the switch on the control panelwithout applying the accelerator pedal. The device can be used when driver would like to drive the vehicle at fixed speed.

1. Set ControlIf the cruise control switch is pushed to – SET side and hand is released from the switch during driving, (The available rangeof set speed: between 40 and 200 km/h) with the ON–OFF switch at ON (Power indicator comes on), the device storesvehicle speed at that time and controls it constantly at the set speed.

2. Set Speed ControlThe device compares the actual vehicle speed with the set speed, and controls the driving power of the motor and theengine by calculating the cruise control requirements to drive it constantly at the set speed.

3. Coast ControlIf the cruise control switch is kept pushed to the – SET side during driving in the cruise control mode, the device recognizesthe cruise control requirement is at zero and decelerates the vehicle speed. When hand is released from the cruise controlswitch, the device stores the vehicle speed while the vehicle speed is decelerating. From then on, vehicle speed iscontrolled to stay at that speed.Every time the switch is operated to – SET side momentarily (For about 0.5 seconds), the set speed is decreased by about1.6 km/h. However, in case of tap–down operation to make more than 5 km/h gap between the set speed and the actualvehicle speed, the device recalls the original set speed and controls it at the speed constantly.

4. Accel ControlIf the cruise control switch is kept pushed to the + RES side during driving in the cruise control mode, the device recognizesthe cruise control is on the acceleration side and accelerates the vehicle speed. When hand is released from the cruisecontrol switch, the device stores the vehicle speed at that time and controls it with the set speed constantly.Every time the switch is operated to + RES side momentarily (For about 0.5 seconds), the set speed is increased by about1.6 km/h. However, in case of tap–up operation to make more than 5 km/h gap between the set speed and the actual vehiclespeed, the device does not change the set speed. (Tap–up operation is not available.)

5. Resume ControlAfter the cruise control mode is cancelled by any one the cancel switches, the mode can be resumed and controlled at theset speed by operating the cruise control switch in the + RES direction providing that the vehicle speed has not droppedbelow the low speed limit [Approx. 40 km/h (25 mph)].The mode cannot be resumed if the vehicle speed once drops below the low speed limit, because the speed in the memoryis cleared.

6. Manual Cancel ControlIf any of the following signals is sent to the device while the vehicle is running in the cruise control, the cruise control iscancelled accordingly.∗ Stop light switch: ON (Depressing the brake pedal)∗ CANCEL switch of control switch: ON∗ ON–OFF switch: OFF

7. Auto Cancel Function

A) The set speed is cleared and the cruise control is canceled under the following conditions. The cruise main indicatorblinks until the main switch is turned OFF. The speed control is unavailable unless the main switch is turned ON again.

∗ When the stop light switch open or short–circuits.∗ When signal of sudden change in the vehicle speed is sent.

B) The set speed is cleared and the cruise control is canceled under the following conditions.∗ When there is malfunction of the stop light switch input circuit.∗ When the vehicle speed becomes lower than 40 km/h.∗ When the vehicle speed becomes lower than the speed that 16 km/h is subtracted from the set speed.

ABS, TRAC and VSC

1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of all the four wheel cylinders toautomatically avoid wheel locking and to ensure the directional and steering stability of the vehicle. Under the situation, theskid control ECU controls the solenoids in the actuators, using the signals from the sensors to move the brake fluid to thereservoir in order to release the braking pressure applied to the wheel cylinder. If the skid control ECU detects that the fluidpressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators to increase the brakingpressure.

2. Electronic Brake–Force DistributionSkid control ECU distributes appropriate brake–force to front and rear wheels (Control of brake–force distribution to front andrear wheels) corresponding to the vehicle driving conditions. It also makes effective use of rear wheel brake–force to matchloading condition and decelerating of the vehicle, resulting to reduce depressing of brake pedal and to ensure effectivebraking. In braking during making a turn, the ECU controls appropriate brake–force distribution to right and left wheels(Control of brake–force distribution to right and left wheels) to ensure stability and braking of the vehicle.

3. Brake Assist SystemSkid control ECU recognizes emergency braking from detecting applying speed of brake pedal and brake travel, andcontrols braking effectiveness to supply strong brake–force for the emergency braking.

4. VSC Operation (w/ VSC)Unexpected road conditions, emergency situation, and any other external factors may cause large under– or over–steeringof the vehicle. If they occur, the VSC system automatically controls the driving power and wheel brakes to reduce the under–or over–steering.To reduce large over–steering :If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering.To reduce large under–steering :If the VSC system determines that the under–steering is large, it controls the driving power and activates the front wheelbrakes and rear inner side wheel brake to reduce the under–steering.If there is malfunction in the VSC system, the VSC indicator lights up to warn the driver.

5. Mutual System ControlDue to cooperative control with hybrid vehicle control ECU, skid control ECU controls hydraulic brake to collect muchelectrical energy by making the most use of regenerative brake.Skid control ECU also improves stability of the vehicle, performing cooperative control with power steering ECU to givesteering torque assistance, corresponding to driving conditions. (w/ VSC)

6. Electric Source Backup FunctionElectric charge is stored in brake control power supply. If voltage of vehicle electricity is declined, electric charge is releasedto cover electric supply to the system.

7. Fail Safe FunctionSkid control ECU monitors the system component parts electrically. In case there is abnormality in ECU, sensor signal andactuator, normal parts except parts with abnormality continue braking operation.Even in case braking is shut off due to malfunction of oil pressure source, braking is secured as master cylinder pressuremade by manpower works on wheel cylinder.In case only regenerative brake is not effective due to abnormality in communication with hybrid vehicle control ECU, controlwill be changed to have oil pressure brake generate all the braking force

SRS

NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started more than 90 seconds after the power SW is pushed to the ”OFF” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back–up power supply from outside the vehicle.

Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

Do not expose the following parts directly to hot air or flame;

Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

For the purpose of reuse, never disassemble and repair the following parts.

If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the frontairbag sensor and deceleration sensor.– Driver Airbag– Front Passenger Airbag– Seat Belt Pretensioner

∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the sideairbag sensors.– Side Airbags– Curtain Shield Airbags

∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls theoptimal airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened(driver seat) and information from the front passenger occupant classification system.

∗ The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult orchild (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat beltis buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, andfront passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through theuse of the AIRBAG ON/OFF indicator lights.

∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when theairbag is deployed.

When power SW is at IG ON position, turning ON rear DEF SW on the steering wheel sends signal to A/C control assembly.Then A/C control assembly flows electricity in TERMINAL Rr DEF, which activates DEF relay and mirror heater relay. As aresult, rear DEF SW and mirror heater is turned on.Turning ON rear DEF SW of multi–display sends signal to A/C control assembly. Then the same action follows as above.During rear window defogger and mirror heater in operation, signal is input in combination meter, lighting rear DEF indicatorin combination meter.

Air conditioning system operates when SW of multi–display or that of steering wheel is turned on. Turning on the SW sendssignal to A/C control assembly, running the air conditioning system.

1. Heater Blower OperationManual operationWhen the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends the signals tothe blower control to control the blower motor speed.Auto operationWhen the auto SW is pushed, the A/C control assembly calculates necessary blower speed from setting of SWs and input ofthe sensors and sends the signals to the blower control to automatically control the blower motor speed.

2. Air Inlet Control Servo Motor ControlWhen the FRESH/RECIRC select SW is set to RECIRC, the air inlet control servo motor starts rotating to move the dampertoward the RECIRC side. The damper position is detected by the TERMINAL TPI of the A/C control assembly. The motorcontinuously rotates until the damper reaches its stop position. When the FRESH/RECIRC select SW is set to FRESH, theair inlet control servo motor starts rotating to move the damper toward the FRESH side. The damper position is detected bythe TERMINAL TPI of the A/C control assembly. The motor continuously rotates until the damper reaches its stop position.In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating themode select SW.

3. Air Vent Mode Control Servo Motor ControlWhen the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor.The servo motor rotates to the position (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF) selected by using the mode select SW,and moves the damper.In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating themode select SW.

4. Air Mix Control Servo Motor ControlBased on the set temperature by the temperature control SW, the ECU in the A/C control assembly sends a signal to the airmix control servo motor. This signal drives the motor to reach the temperature set by the temperature control SW, and movesthe film damper.

5. Humidity Sensor ControlA/C control assembly detects humidity in passenger room when A/C is turned on, with humidity detecting function of A/C room temp. sensor and controls to dehumidify for comfortable condition

6. Air Conditioning OperationA/C control assembly calculates target cooled temperature from information such as that of operating SWs, roomtemperature, humidity, ambient temperature and insolation to have target running speed of compressor assembly (Motor).The calculated control signal is sent to inverter to drive compressor assembly (Motor) (Electric motor) with control of inverter,resulting in operating A/C.
