BODY AND ELECTRICALDOOR LOCKELECTRIC DOOR LOCK SYSTEMOPERATION CHECK1. CHECK ELECTRIC DOOR LOCK
(a) Check that all of the doors lock when the door lock knob (formanual operation) of the driver's door is turned to LOCK. Also,check that all of the doors unlock when the door lock knob isturned to UNLOCK.
(b) Check that the key-linked operation works from outside of thevehicle. Do this by making sure that all of the doors lock whenthe driver's side door lock is turned to LOCK, and that all of thedoors unlock when turned to UNLOCK.
(c) Check the key lock-in prevention function.NOTICE:In order to prevent key lock-in, perform the check with thedoor window open.(1) Have the ignition key inserted in the ignition switch lock
cylinder.(2) With any door open, perform the following lock opera-
tions. Then check immediately that the unlocking functionworks as well.• Turn the door lock knob on the driver's side door in the
LOCK direction. (immediately)• Using the driver's side door key operation, turn the
door lock knob in the LOCK direction. (immediately)• Lock the vehicle by holding down the door lock knob
on the driver side door to the locked side for at leasttwo seconds. Then shut the driver's side door. (Unlockafter 1 sec)
(d) Check illumination functionHINT:• The room light comes on and goes off using the illumination
function. • The room light functions when the switch is in the DOOR
position. (1) Check that each of the lights goes on when the doors are
unlocked by using the key operation in the driver's sidedoor. Also check that each light goes out in about 15 sec-onds if none of the doors are open after the door unlockoperation is completed.

DESCRIPTIONThrough the unlock warning switch assembly, the combination meter assembly (meter ECU) detects the presence or absence ofa key in the ignition system switch lock cylinder. When a door is locked while any of the doors is still open and the key is in theignition switch lock cylinder, the door control relay assembly transmits an UNLOCK signal (after first sending a LOCK signal) tothe lock motors in all of the doors. This prevents the doors from being locked.

BODY AND ELECTRICALDOOR LOCKWIRELESS DOOR LOCK CONTROL SYSTEMOPERATION CHECK1. NOTICES WHEN CHECKING
(a) The wireless door lock remote control functions only when thefollowing 3 conditions are satisfied.(1) All the doors are closed.(2) The key plate is not inserted in the ignition switch lock cyl-
inder.(3) The electric door lock operates normally.
(b) The operating range of the wireless door lock remote controlfunction may vary depending on the following conditions. (1) The operating range may change depending on how the
remote control is held and depending on who is operatingthe remote control.
(2) The operational range may decrease due to the shape ofthe vehicle body and the influence of the surroundingenvironment. There may be places where only partialfunctionality is experienced.
(3) The remote control uses weak radio waves. Therefore,operating range may decrease, or the device may notfunction at all in places where there is interference from astrong signal or there are a number of frequencies in use,
(4) If the battery is low, the operating range may decrease, orthe device may not function at all.HINT:Placing the door control transmitter in direct sunlight, suchas on a dashboard, may cause the battery life to shortenor the battery to stop functioning.
2. INITIAL VEHICLE STATE (THAT SATISFIES CONDITIONS FORWIRELESS OPERATION)NOTICE:Indicates initial settings that are not selected in the CUSTOMIZEfunction by the DS-II.(a) The key is not inserted in the ignition switch lock cylinder.(b) All doors are closed. (door warning inside meter is not on)
3. CHECK WIRELESS DOOR LOCK CONTROL OPERATION(a) CHECK BASIC FUNCTION
HINT:The switches described below transmit LOCK / UNLOCK sig-nals and are built in to the door control transmitter.(1) Check the wireless operation within the remote control's
operating range. Note that if the key is in the ignitionswitch lock cylinder, or if any of the doors is open, theremote control will not operate.
(b) Check the chattering prevention function.(1) If the switch is held down, check that the corresponding
operation occurs only once and does not repeatedly acti-vate. However, if a switch is pressed and released at 1second intervals, check that the corresponding operationactivates once for ever press of the switch.
DL–36 DOOR LOCK - WIRELESS DOOR LOCK CONTROL SYSTEM
DL
(c) Check the automatic locking function.(1) Check that, when all of the doors are unlocked with the
UNLOCK switch and none of the doors are opened orlocked within 30 seconds, the doors lock again automati-cally.
(2) Under the same conditions as those described above,check that, if any of the doors are opened or all of thedoors are locked within 30 seconds, the doors will not lockagain automatically.
(d) Check the switch operation fail-safe function.(1) If the key is in the ignition switch lock cylinder, check that
the doors cannot be locked or unlocked by using theLOCK switch. However, this does not apply when the sys-tem is in the recognition code registration mode.
(2) Check that when a switch is pressed on an unregisteredtransmitter, the LOCK / UNLOCK functions will not oper-ate. Also, check that when a switch is pressed on a regis-tered transmitter, these functions will operate.
(e) Check the door ajar warning function.(1) When a door is open or not completely closed, check that
the doors cannot be locked by using the LOCK switch.(f) Check the repeat function.
(1) Check that, when the LOCK switch is pressed with thedriver door control knob held forcibly in the UNLOCK posi-tion, all doors will lock again about 1 second later.
(g) Check the answer-back function.(1) When the LOCK switch is pressed, check that, when all
doors are either locked or unlocked, the hazard warninglights also flash. They should flash once when the door islocked and twice when the door is unlocked.

DESCRIPTIONThe door control receiver receives a signal from the transmitter and the signal is sent to the combination meter assembly (meterECU).The combination meter assembly sends the door lock, unlock signals to the door control relay assembly using body multi-plex communication (LIN). The door control relay assembly outputs a hazard light blinking signal (answer back) according to thedoor lock or unlock signal.NOTICE:The wireless door lock control system uses the Body Electrical Area Network. Following the HOW TO PROCEED WITHTROUBLESHOOTING section, go to CHECK COMMUNICATION FUNCTION and proceed to TROUBLESHOOTING.

DESCRIPTIONThe signal from the door lock control transmitter is sent to the combination meter assembly via the continuous line that the doorcontrol receiver receives. Then, via the combination meter assembly, it is changed by the Body Electrical Area Network and sentto the fuse block assembly (door control relay assembly). The fuse block assembly (door control relay assembly) controls bysending the door lock/unlock signal to each of the door lock actuators.NOTICE:The wireless door lock control system uses the Body Electrical Area Network. Following the HOW TO PROCEED WITHTROUBLESHOOTING section, go to CHECK COMMUNICATION FUNCTION and proceed to TROUBLESHOOTING.

DESCRIPTIONThrough the unlock warning switch assembly and each door's courtesy light switch, the combination meter assembly senseswhether each door is opened or closed and whether a key is present or absent in the ignition switch lock cylinder. Furthermore, bysensing the open signal from each door's courtesy light switch and the signal that there is a key in the ignition, the combinationmeter assembly decides to issue a key reminder and intermittently sounds the buzzer of the built-in meter.
