Only Wireless Control Function Is Inoperative
DOOR LOCK: WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System): Only Wireless Control Function is Inoperative
- Only Wireless Control Function is Inoperative
DESCRIPTION
The door control receiver receives signals from the transmitter and sends these signals to the main body ECU. The main body ECU then controls all doors by sending lock / unlock signals to each door, and sends hazard flasher relay signals to the turn signal flasher relay (hazard warning lights).

INSPECTION PROCEDURE
PROCEDURE
1. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
(a) Check the wireless door lock control functions Operation Check.
OK:
Each function of wireless door lock control system operates normally using transmitter switch.
NG -- CHECK TRANSMITTER LED ILLUMINATION
OK -- END
2. CHECK TRANSMITTER LED ILLUMINATION
(a) Check that the transmitter's LED illuminates 3 times when the switch is pressed 3 times.
OK:
Transmitter's LED illuminates 3 times when switch is pressed 3 times.
NG -- CHECK TRANSMITTER BATTERY (OPERATION)
OK -- Continue to next step.
3. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (STANDARD OPERATION FUNCTION)
HINT
Use the following standard test procedure to check the transmitter again.
(a) Hold the transmitter approximately 1 m (3.28 ft.) from the driver side door outside handle. The transmitter must be held parallel to the ground and perpendicular to the side of the vehicle.
(b) Press and hold either the LOCK or UNLOCK transmitter switch for 1 second, and check that the doors are locked or unlocked accordingly.
OK:
Doors can be locked and unlocked with transmitter switches.
NG -- CHECK ROOM LIGHT (WIRELESS DOOR LOCK BUZZER)
OK -- Continue to next step.
4. CHECK TRANSMITTER BATTERY (OPERATION)
(a) Temporarily replace the transmitter battery with a new or normally functioning one. Removal
(b) Check that the doors can be locked and unlocked using the transmitter switches.
OK:
Doors can be locked and unlocked with transmitter.
NG -- REPLACE DOOR CONTROL TRANSMITTER MODULE
OK -- END (TRANSMITTER BATTERY IS DEFECTIVE)
5. CHECK ROOM LIGHT (WIRELESS DOOR LOCK BUZZER)
(a) Check that the room light illumination operates normally.
(b) Inspect the wireless door lock buzzer No Answer-Back.
Result:
C -- REPLACE WIRELESS DOOR LOCK BUZZER
B -- Go to LIGHTING SYSTEM
A -- Continue to next step.
6. SWITCH TO SELF-DIAGNOSTIC MODE
(a) Switch to self-diagnostic mode by operating the ignition key cylinder.
(1) Make sure the vehicle is in its initial condition. Then insert the key into the ignition key cylinder and remove it.
(2) Within 5 seconds of removing the key, insert the key into the ignition key cylinder (ignition switch OFF). Then turn the ignition switch ON and OFF.
(3) Within 30 seconds of turning the ignition switch OFF, perform the following operation 9 times: turn the ignition switch ON and OFF.
NOTICE:
If the system cannot enter self-diagnostic mode, the system returns to normal mode.
HINT
* Turning the ignition switch ON after the above operations have been completed ends self-diagnostic mode.
* Do not lock or unlock doors during self-diagnostic mode.
(b) Check that the system has switched to self-diagnostic mode by checking the room light flash (wireless door lock buzzer sound) pattern.
OK:
Flash (sound) pattern is same as illustration.
NG -- INSPECT UNLOCK WARNING SWITCH ASSEMBLY
OK -- Continue to next step.
7. CHECK BY SELF DIAGNOSTIC MODE
(a) Inspect the diagnosis outputs when the door control transmitter switch is held down. The diagnosis outputs can be checked by the flash patterns of the room light (wireless door lock buzzer).
Result:
C -- CHECK DOOR CONTROL RECEIVER (RESPONSE)
B -- REPLACE INSTRUMENT PANEL JUNCTION BLOCK (MAIN BODY ECU)
A -- Continue to next step.
8. REGISTER RECOGNITION CODE
(a) Check that the system can be switched to rewrite mode or add mode, and that a recognition code can be registered Registration.
OK:
Recognition code can be registered.
NG -- CHECK DOOR CONTROL TRANSMITTER MODULE
OK -- END
9. CHECK DOOR CONTROL RECEIVER (RESPONSE)
(a) Temporarily replace the door lock control transmitter with a new or normally functioning one Removal.
(b) Held down the door control transmitter's switch.
(c) Check that an unmatching recognition code is output.
OK:
Unmatching recognition code is output.
NG -- CHECK DOOR CONTROL RECEIVER (OPERATION)
OK -- REPLACE DOOR CONTROL TRANSMITTER MODULE
10. CHECK DOOR CONTROL RECEIVER (OPERATION)
(a) Temporarily replace the door lock control receiver with a new or normally functioning one Removal.
(b) Check that the doors can be locked and unlocked by using the transmitter LOCK and UNLOCK switches.
OK:
Doors can be locked and unlocked with transmitter.
NG -- REPLACE INSTRUMENT PANEL JUNCTION BLOCK (MAIN BODY ECU)
OK -- END (DOOR CONTROL RECEIVER IS DEFECTIVE)
11. INSPECT UNLOCK WARNING SWITCH ASSEMBLY
(a) Remove the switch.
(b) Measure the resistance of the switch.
Standard resistance:
NG -- REPLACE UNLOCK WARNING SWITCH ASSEMBLY
OK -- Continue to next step.
12. CHECK WIRE HARNESS (UNLOCK WARNING SWITCH - MAIN BODY ECU AND BODY GROUND)
(a) Disconnect the E6 receiver connector.
(b) Disconnect the IE junction block connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
13. CHECK DOOR CONTROL RECEIVER (OUTPUT)
(a) Reconnect the L18 receiver connector.
(b) Measure the voltage of the connector.
Standard voltage:
NG -- CHECK DOOR CONTROL TRANSMITTER MODULE
OK -- REPLACE INSTRUMENT PANEL JUNCTION BLOCK (MAIN BODY ECU)
14. CHECK DOOR CONTROL TRANSMITTER MODULE
(a) Temporarily replace the door control transmitter module with a new or normally functioning one Removal.
(b) Check that the doors can be locked and unlocked by using the transmitter LOCK and UNLOCK switches.
OK:
Doors can be locked and unlocked with transmitter.
NG -- REPLACE DOOR CONTROL RECEIVER
OK -- END (DOOR CONTROL TRANSMITTER MODULE IS DEFECTIVE)
