Engine Control for 2UZ–FE
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 as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B and OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal isinput into 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 TERMINALSVTA1 and VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine controlmodule via the combination meter, from TERMINAL SP1 of the skid control ECU with actuator.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B and +B2 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 as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1 and KNK2 of the engine controlmodule as a control signal.
(12)A/C SW signal systemThe operating voltage of the A/C magnetic clutch is detected and input in the form of a control signal to TERMINAL AC1of the engine control module.
(13)Air fuel ratio signal systemThe air fuel ratio is detected by air fuel ratio sensor and input as a control signal into TERMINALS A1A+ and A2A+ ofengine control module.

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, #40, #50, #60, #70 and #80 to operatethe injector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to thedriving 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 memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7 and IGT8, and these signals control theigniter to provide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINAL HT1B or HT2B to control the heater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system 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 detection performance of the sensor.The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2A,controlling the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump withthe FUEL PUMP relay.
∗ ACISThe ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in allranges from low to high speeds.
∗ ETCS–iThe ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
∗ Engine start control systemThe engine control module allows power to be supplied from the TERMINAL STAR/NSW to the STA relay via park/neutralposition SW until complete combustion is confirmed by engine RPM after the detection of ignition SW ST signal by theTERMINAL STSW.With this arrangement, engine can be started without holding the ignition key in the ST position. At the same time, theTERMINAL ACCR is controlled so that the engine control module turns off ACC CUT relay, shutting off power to theaccessories.
∗ VVT–iControls the intake camshaft to an optimal valve timing in accordance with the engine condition.
∗ Air Injection SystemIt is the system to improve exhaust control performance by activating catalyst at early stage, which is realized when air ispressed and sent into the exhaust pipe forcibly by the air injection pump at starting engine in cold condition.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail–Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail–safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

Engine Control for 1GR–FE
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 as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B and OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the VVT sensor LH and RH, and is input into TERMINALS VV1+ and VV2+ of theengine control module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and thesignal is input into 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 TERMINALSVTA1 and VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine controlmodule via the combination meter, from TERMINAL SP1 of the skid control ECU with actuator.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B and +B2 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 as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1 and KNK2 of the engine controlmodule as a control signal.
(12)A/C SW signal systemThe operating voltage of the A/C magnetic clutch is detected and input in the form of a control signal to TERMINAL AC1of the engine control module.
(13)Air fuel ratio signal circuitThe air fuel ratio is detected and input as a control signal into TERMINALS A1A+ and A2A+ of the engine controlmodule.
System Outline
4RUNNER (EM00T0U)

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, #40, #50 and #60 to operate theinjector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the drivingconditions.
∗ 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 memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5 and IGT6, and these signals control the igniter toprovide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINAL HT1B or HT2B to control the heater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system 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 detection performance of the sensor.The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2A,controlling the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump withthe FUEL PUMP relay.
∗ ACISThe ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in allranges from low to high speeds.
∗ ETCS–iThe ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
∗ Engine start control systemThe engine control module allows power to be supplied from the TERMINAL STAR/NSW to the STA relay via park/neutralposition SW until complete combustion is confirmed by engine RPM after the detection of ignition SW ST signal by theTERMINAL STSW.With this arrangement, engine can be started without holding the ignition key in the ST position. At the same time, theTERMINAL ACCR is controlled so that the engine control module turns off ACC CUT relay, shutting off power to theaccessories.
∗ VVT–iControls the intake camshaft to an optimal valve timing in accordance with the engine condition.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail–Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail–safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

Headlight
(w/ daytime running light)∗ This system is designed to automatically activate the turn signal lights during the daytime to keep the car highly visible to
other vehicles. This system is controlled by the body ECU. This system makes use of the turn signal lights as daytime running lights.For this reason, when the turn signal lights are operated, the daytime running lights function is interrupted momentarily,which, however, will be brought back into operation as soon as the interposed operation is over.
∗ This system is enabled when the conditions given below are met.
A) Ignition switch ON condition
B) Turn signal light switch OFF condition
C) Hazard light switch OFF condition
D) Light control switch OFF condition
E) Parking brake switch OFF condition (Parking brake out of operating condition)**
**: This system does not become active when the parking brake switch is ON. However, once the OFF signal of the parking brake switch is input into the body ECU, this system will become active thereafter, regardless of whether the parking brake switch is ON or OFF.

With the ignition SW turned on, the current flows to TERMINAL 17 of the wiper and washer SW, TERMINAL 1 of the washermotor and TERMINAL 2 of the front wiper motor through the FR WIP–WSH fuse.
1. Low Speed PositionWith the wiper and washer SW turned to LO position, the current flows from TERMINAL 17 of the wiper and washer SW toTERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to runat low speed.
2. High Speed PositionWith the wiper and washer SW turned to HI position, the current flows from TERMINAL 17 of the wiper and washer SW toTERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to runat high speed.
3. INT PositionWith the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL 17 of thewiper and washer SW to TERMINAL 2 to GROUND. This activates the intermittent circuit and the current flows fromTERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 toGROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in therelay.
4. Washer Interlocking OperationWith the wiper and washer SW pulled to washer position (Washer SW ON position), the current flows from the FR WIP–WSHfuse to TERMINAL 1 of the washer motor to TERMINAL 2 to TERMINAL 11 of the wiper and washer SW to TERMINAL 2 toGROUND and causes the washer motor to run and the window washer to spray. Simultaneously, current flows from the FRWIP–WSH fuse to TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor toTERMINAL 5 to GROUND, causing the wiper to function.

Door lock control (Lock and unlock), back window control (Back window open) and panic control (Theft alarm and flash) isperformed by remote control, without the ignition key inserted in the door key cylinder, using low–power electrical wavesemitted by a transmitter.
1. Normal Operation∗ Lock operation
When the lock SW on the transmitter is pressed, all the doors are locked.∗ Unlock operation
When the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressedagain within 3 seconds, all the doors are unlocked.
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 are automatically locked. If any of the following conditions are detected, the wireless door lock doesnot function.∗ Any door is opened.∗ The ignition key is inserted into the ignition SW.∗ When the lock detection SW of all the doors are locked.
3. Wireless Door Lock Stop FunctionIf any of the following conditions are detected, the wireless door lock does not function.Lock operation∗ When any door is open (Door courtesy SW on)∗ The ignition key is inserted into the ignition SW (Unlock warning SW on)∗ Ignition SW is onUnlock operation∗ Ignition SW is on
4. Buzzer Sound FunctionDuring lock operation, when the body ECU receives a lock signal from the door lock detection SW, the wireless door lockbuzzer goes on once. During unlock operation, when the body ECU receives an unlock signal from the door lock detectionSW, the wireless door lock buzzer goes on twice.With any door open, when the body ECU receives a lock signal from the transmitter, the wireless door lock buzzer goes onfor approx. 10 seconds. If the door is closed, or ignition SW is on, or if the unlock signal is received from the transmitter whilethe buzzer is on, the buzzer stops.
5. 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 light isflashed once. During unlock operation, when the body ECU receives an unlock signal from the door lock detection SW, theturn signal light is flashed twice.
6. 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 light, headlights and taillight flash. Then, the panic orthe unlock button (Transmitter) is pushed once more, interior lights are turned off, sounding and flashing will stop. Panic willnot function when ignition key is in ignition key cylinder.
7. Repeat FunctionIf the lock detection signal in response to the output signal is not received after the body ECU has output the lock signal, thelock signal is output again.
8. Buzzer Volume ControlThe volume of the wireless door lock buzzer can be set among 5 steps by operating the transmitter, when the ignition SW isoff, any door open, and the ignition key is not in the ignition key cylinder.
9. Back Window ControlWhen the ignition SW is off, the ignition key is not inserted into the ignition key cylinder, the back window can be opened bypressing the back window open SW of the transmitter for approximately 0.8 seconds. At that time, the wireless door lockbuzzer beeps once.
10. Illuminated Entry FunctionWhen the body ECU detects the unlock state after the unlock operation has been made, it turns on the lights, such as theignition key cylinder light and interior light for approx. 15 sec. If all the doors are locked during this operation, lighting iscancelled and the lights immediately fade out.

4RUNNER (EM00T0U)
ECT and A/T Indicator for 2UZ–FE
Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electricallycontrols the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. Theelectronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response tothe vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible byshift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,squat and gear shift shock when starting off.
1. Gear Shift OperationWhen driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from theengine coolant temp. sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL SP2+ of theengine control module. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA1 and VTA2 of the engine control module as throttle angle signal.Based on these signals, the engine control module selects the best shift position for the driving conditions and sends currentto the electronically controlled transmission solenoid.
2. Line Hydraulic Pressure ControlThe engine control module adjusts the line hydraulic pressure to the optimal level by controlling TERMINAL SLT+ of themodule according to the engine torque data. This realizes the smooth gear shifting.
3. High Response Gear Shifting ControlThe engine control module performs the high response engine torque up control to control the ignition–timing lag as well asopening the electronic throttle when shifting down. By doing this, the gear shifting is performed in a short period of time.Moreover, the engine control module uses the orifice switching control, which optimizes the speed of applying and reducingthe hydraulic pressure. And it realizes the fine shifting condition by applying and reducing hydraulic pressure slowly whenthe gear shifting shock is important and quickly when the high response is required.
4. Clutch Hydraulic Pressure ControlThe engine control module controls the clutch operation in the optimal timing and with the best hydraulic pressure accordingto the engine torque data and the number of the clutch revolution
5. Lock–Up and Flexible Lock–Up ControlThe engine control module carries out the lock–up control by controlling the TERMINAL SLU+ of the module according tothe shift position, vehicle speed, throttle opening degree and running conditions. The engine control module also steadilykeeps applying the lock–up clutch a delicate slippage to improve the transmission efficiency (Fuel efficiency) of the torqueconverter.
6. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock–up condition, a signal is input to TERMINAL STP ofthe engine control module. The engine control module operates and cuts the current to the solenoid to release lock–up.
7. AI–Shift ControlThe engine control module judges whether the road is downslope or upslope by detecting the throttle opening degree or thevehicle’s speed. Moreover it can expect the winding roads by detecting the turning condition of the vehicle. The enginecontrol module keeps unnecessary shifting up from the fourth gear from operating and carries out the automatic shiftingdown to the third gear in order to control the vehicle running according to the road conditions. The engine control modulealso reads the driver’s intention during driving from his (her) accelerating operation and the running conditions of the vehicle.As a result of that, ideal shifting patters for each driver are automatically selected without any switching operations.

Cruise Control for 2UZ–FE
The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makesit possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
1. Set OperationWhen the ON–OFF SW is turned on, the system starts preparations necessary for the cruise control and turns on theindicator light in the combination meter.
2. Set Speed ControlWhen the – SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed iscontrolled.
3. Coast ControlWhen the – SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve todecelerate the vehicle. Every time the – SET SW is turned on instantaneously, the vehicle speed is deceleratedapproximately 1.5 km/h.
4. Accel ControlWhen the + RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve toaccelerate the vehicle. Every time the + RES SW is turned on instantaneously, the vehicle speed is acceleratedapproximately 1.5 km/h.
5. Resume ControlWhen the vehicle speed is above the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, useof the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control.
6. Manual Cancel MechanismIf any of the following signals is input during cruise control travelling, the cruise control is cancelled.∗ The stop light SW is turned on.∗ The CANCEL SW is turned on.∗ The ON–OFF SW is turned off.∗ Gear is shifted from D position to other positions than D.
7. Auto Cancel Operation∗ If any of the following conditions are detected, the set speed is erased and the control is canceled.(1) Disconnection and/or short in the stop light SW
(2) Malfunction in the vehicle speed signal
(3) Malfunction in the electronic throttle parts
(4) Malfunction in the stop light SW input circuit
(5) Malfunction in the cancel circuit
(6) The actual vehicle speed becomes –16 km/h slower than the set speed∗ If the following condition is detected, the set speed is kept and the control is canceled.(1) The actual vehicle speed becomes slower than the minimum speed limit.
8. Overdrive Control FunctionOverdrive is sometimes cut off on gradients during cruise control driving. When end of climbing gradient is determined bythrottle opening degree information after overdrive is canceled, control is reset to overdrive condition after overdrive resettingtimer operation. Also, when overdrive is cut off during accelerator resuming control, control is reset to overdrive conditionwhen accelerator resuming control is finished.

1. Normal OperationThe VSC system helps prevent the vehicle from slipping sideways as a result of strong front wheel skid or strong rear wheelskid during cornering.The followings are two possible circumstances in which the tires exceed their lateral grip limit. The VSC system is designedto help control the vehicle behavior by controlling the engine output and the brake at each wheel when the vehicle is underone of the conditions indicated below.∗ When the front wheels lose grip in relation to the rear wheels (Strong front wheel skid tendency).∗ When the rear wheels lose grip in relation to the front wheels (Strong rear wheel skid tendency).
2. Electronic Brake–Force DistributionSkid control ECU with actuator distributes appropriate brake–force to front and rear wheels (Control of brake–forcedistribution to front and rear wheels) corresponding to the vehicle driving conditions. It also makes effective use of rear wheelbrake–force to match the loading condition and decelerating of the vehicle, resulting in reducing brake pedal depression andensuring effective braking. In braking during making a turn, the ECU controls appropriate brake–force distribution to right andleft wheels (Control of brake–force distribution to right and left wheels) to ensure stability and braking of the vehicle.
3. Downhill Assist Control OperationThe downhill assist control operation controls braking action of each wheel to help prevent an out–of–balance posture of thevehicle when descending a steep hill or traveling at a speed exceeding the threshold of wheel gripping capability. When thedownhill assist control is in operation, the brake system controls vehicle speed within the range of 5 to 7 km/h.For the downhill assist control to be operative, all of the following conditions have to be met:∗ Downhill assist control switch = ON∗ Transfer L4 selected∗ Vehicle speed is 5 km/h or more, but less than 25 km/h.∗ Accelerator pedal OFF∗ Brake pedal OFF
4. Hill–Start Assist Control OperationWhen starting on a steep hill for ascending, the hill–start assist control automatically puts the brake on momentarily when thedriver switches from the brake pedal to the accelerator pedal, to help the driver start the vehicle safely and smoothly.Please bear in mind, however, that it activates the brake system only for 3 seconds.For the hill–start assist control to be operative all of the following conditions have to be met:∗ Shift position = D, 2, or L∗ No vehicle move due to wheel slip∗ Vehicle speed > 0 km/h
5. Active TRAC (4WD)During rugged off–road driving, this function controls the engine output and the brake fluid pressure that is applied to theslipping wheel, and distributes the drive force that would have been lost through the slippage to the remaining wheels inorder to achieve a LSD effect.
6. Auto LSD (2WD)Auto LSD fulfills the function of LSD by using the system of TRAC. It helps ensures to recover from run–off condition and totake off on roads with much travel resistance such as sand.

AHC and Electric Modulated Air Suspension
∗ The electric modulated suspension with height control is a system designed to maintain a constant vehicle height bymeans of an electro–pneumatic system in the rear suspension to cope with change in load such as passenger numberand/or weight of cargo in the vehicle. With the three–height–control switch on the console, the driver can set the vehicleheight from the three different height modes (High, normal and low): ”High mode” for rough terrain and ”Low mode” forpassenger to get on/off, and for cargo to be loaded/unloaded.
∗ This system has five basic controls as shown below:∗ Auto leveling control
This control maintains a constant rear vehicle height regardless of change in load such as passenger number and/orweight of cargo in the vehicle.
∗ Vehicle height switchover controlThis control switches the height mode to the mode selected with the height control switch.∗ High mode (+ 40 mm / 1.6 in.)∗ Low mode ( – 20 mm / 0.8 in.)
∗ Speed sensing controlRegardless of the initial setting of the vehicle height, ”High mode” or ”Low mode,” this control automatically switches thevehicle height mode to the optimum ”Normal mode” in the following conditions:∗ When the vehicle speed reaches or exceeds 30 km/h with ”High mode,” or;∗ When the vehicle speed reaches or exceeds 5 km/h with ”Low mode.”
∗ Subsequent control after ignition switch offAfter the ignition switch is turned OFF, this control lowers the rear vehicle height for passengers to get off, etc.
∗ Height control OFF controlIf the system is turned OFF with the vehicle height control switch, the vehicle can be jacked up or towed.

Multi Mode 4WD
Depending on the transfer shift actuator status and ADD actuator (1GR–FE) status, the 4WD control ECU drives the transfershift actuator and ADD actuator (1GR–FE) to electrically change the gear position selected by the driver according to vehiclespeed signal and neutral start switch signal.
1. Shift Select ControlShifting from H2 into H4 position (1GR–FE)When the 4WD control switch is turned from H2 into H4, this signal is input into 4WD control ECU (TERMINAL 2–4). Then,the 4WD control ECU moves the 2–4 select motor (TERMINAL 2, TERMINAL 1) in the transfer shift actuator until the shiftfork shaft shifts to the diff. free position, performing a shift into H4 position
Switching diff. lock ON when in H4 position.When the diff. lock switch is turned ON with the 4WD control switch in H4 position, this signal is input into the 4WD controlECU (TERMINAL DL). Then, the 4WD control ECU drives the 2–4 select motor (TERMINAL 2, TERMINAL 1) in the transfershift actuator until the shift fork shaft shifts to the diff. lock position, locking it in H4 position with the diff. lock.
Shifting from H4 into L4 positionWhen the 4WD control switch is turned from H4 into L4, this signal is input into 4WD control ECU (TERMINAL LO). Then, the4WD control ECU drives the H–L select motor (TERMINAL 8, TERMINAL 7) in the transfer shift actuator, shifting the shiftfork shaft, performing a shift into L4 position.
Switching diff. lock ON when in L4 position.When the diff. lock switch is turned ON with the 4WD control switch in L4 position, this signal is input into the 4WD controlECU (TERMINAL DL). Then, the 4WD control ECU drives the 2–4 select motor (TERMINAL 2, TERMINAL 1) in the transfershift actuator until the shift fork shaft shifts to the diff. lock position, locking it in L4 position with the diff. lock.
2. Function of Limit SwitchH4L limit switch (TERMINAL 12 and TERMINAL 11 of transfer shift actuator)The H4L limit switch in the transfer shift actuator feeds back the current shift position status (H4 or L4) information, which isbased on the ON/OFF combination of the two switches, to the 4WD control ECU.
4WD limit switch (TERMINAL 3 (1GR–FE), TERMINAL 4 and TERMINAL 5 of transfer shift actuator)The 4WD limit switch in the transfer shift actuator feeds back the current shift position status (H2 or H4) (1GR–FE) and diff.lock or diff. free status information, which is based on the ON/OFF combination of the two (2UZ–FE) or three (1GR–FE)switches, to the 4WD control ECU.
ADD limit switch (TERMINAL 6 and TERMINAL 5 of ADD actuator) (1GR–FE)The ADD limit switch in the ADD actuator feeds back the current front diff. lock or free status information, which is based onthe ON/OFF combination of the two switches, to the 4WD control ECU.
3. Shift Limit ControlThe 4WD control ECU interrupts the shift select control and gives the driver a warning by means of buzzer (Integrated intothe ECU) sound and blinking indicator light on the combination meter when the following shift change conditions exist.The warning, however, can be canceled when the 4WD control switch is canceled and the switch position is returned to theoriginal position before the warning occurred.∗ Shift change (1GR–FE) from H2 into H4 with vehicle traveling at a speed reaching or exceeding 100 km/h (Buzzer sound
and blinking 4WD and center diff. lock indicator lights)∗ Shift change from H4 into L4 with vehicle traveling at a speed reaching or exceeding 5 km/h but with the A/T shift position
N range (Buzzer sound and blinking L4 indicator light)
4. ADD Actuator Control (1GR–FE)When switching over between H2 (2WD) and H4 (4WD), the 4WD control ECU controls the way in which power is suppliedto the ADD motor in the ADD actuator, as shown below, to run the ADD motor in normal or reverse direction, therebychanging the status of the front diff. from free to lock, or vice versa.

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 ignition SW is turned to the ”LOCK” 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.
Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
After work on the SRS is completed, check the SRS warning light.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

SRS
∗ 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.
∗ A Roll Sensing Curtain Shield Airbag system has been adopted in order to deploy the curtain shield airbags and thepretensioners, in the event that the vehicle rolls over.
∗ A Roll Sensing Curtain Shield Airbag cutoff SW is provided near the driver side to enable the driver to disable this system.∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when the
airbag is deployed.

Moon Roof
Current is always applied from the POWER fuse to TERMINAL 10 of the moon roof control ECU. With the ignition SW turnedon, the current flows to TERMINAL 9 of the moon roof control ECU.
1. Moon Roof Open/Close OperationFor moon roof operation, there are moon roof control switches: ”Slide open/tilt down”; and ”Slide close/tilt up.” When a switchis pressed and held down for a certain period of time, one touch automatic operation takes place in accordance with thefunction of the switch.
2. Key–Off OperationRoof remains operable – until about 45 seconds elapse after the ignition SW is turned from ON to OFF or until the driver’sseat door is opened and closed, whichever first occurs.However, if an overload reverse operation was going on at that time, the key–off operation continues until it comes to an end.
3. Overload Reverse OperationThe moon roof control ECU detects jamming of the moon roof by foreign material, if occurred, from abnormal motor speedsignal and reverses the moon roof operation.
4. Deflector Control FunctionWhen the roof is slid fully open, the moon roof control ECU automatically adjusts the height of deflector in accordance withthe vehicle cruising speed.
∗ When the battery terminal or fuse is disconnected, the roof position has to be reset to its initial position by the moon roofcontrol SW in accordance with the following procedure:
(1) Reconnect the battery terminal or fuse.
(2) Turn ON the ignition switch.
(3) Operate the moon roof control SW to open the roof halfway or more.
(4) Then operate the moon roof control SW to fully close the roof.Do not release the switch for at least one second after the roof is fully closed.

When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 6 of the shift lock controlECU. When the ignition SW is turned to ON position, the current from the ECU–IG fuse flows to TERMINAL 1 of the shift lockcontrol ECU.
1. Shift Lock MechanismIf the brake pedal is depressed with the ignition SW set at ON (The stop light SW is on), the shift lock control ECU isactivated, allowing the driver to change the shift lever to a position other than the P position.
2. Key Interlock MechanismWith the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock leverdisengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

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 sends the signals from various sensors and temperature SW to theblower 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 motor in the air inlet control servo motor starts rotating to movethe damper toward the RECIRC side. Since the damper position is detected by the TERMINAL TPI of the A/C controlassembly, the motor is continuously rotated until the damper reaches its stop position. When the FRESH/RECIRC select SWis set to FRESH, the motor in the air inlet control servo motor starts rotating to move the damper toward the FRESH side.Since the damper position is detected by the TERMINAL TPI of the A/C control assembly, the motor is continuously rotateduntil the damper reaches its stop position.
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.This causes the servo motor to rotate to the position (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF) selected using the modeselect SW, and moves the damper.
4. Air Mix Control Servo Motor Control (Limited)When the temperature control SW on the driver’s side is pressed, the ECU in the A/C control assembly sends a signal to theair mix control servo motor on the driver’s side. This signal drives the motor to reach the temperature set by the temperaturecontrol SW on the driver’s side, and moves the damper. Passenger’s side is operated as same as the driver’s side.
5. Air Mix Control Servo Motor Control (Except Limited)When the temperature control SW is pressed, the ECU in the A/C control assembly sends a signal to the air mix controlservo motor. This signal drives the motor to reach the temperature set by the temperature control SW, and moves the filmdamper.
6. Air Conditioning OperationThe A/C control assembly receives various signals, I.E., the engine RPM from the engine control module, out side airtemperature signal from the A/C ambient temp. sensor and coolant temperature from the engine control module, etc.When the engine is started and the A/C SW (A/C control assembly) is on, a signal is input to the A/C control assembly.As a result, turning the MG CLT relay on, so that the magnetic clutch is on and the A/C compressor operates.If the A/C control assembly detects the following conditions, it stops the air conditioning:∗ Evaporator outlet air is too low.∗ There is a marked difference between the compressor speed and the engine speed.∗ The refrigerant pressure is abnormally high or abnormally low.∗ The engine speed is too low.∗ Rapid acceleration occurs.
