WIRELESS DOOR LOCK CONTROL SYSTEM (for Non-built-in Type Door Control Receiver) Only Wireless Control Function is Inoperative

DESCRIPTION

The door control receiver receives signals from the transmitter and sends these signals to the instrument panel junction block (integration relay). The instrument panel junction block (integration relay) then controls all doors by sending lock / unlock signals to each door and hazard flasher relay signals to the turn signal flasher relay (hazard warning lights).

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS

    OK
    Each function of wireless door lock control system operates normally using transmitter switches (see page Click here).

    OK

    END

    NG

  2. CHECK THAT TRANSMITTER LED ILLUMINATES


    1. 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

    REPLACE TRANSMITTER BATTERY Click here

    OK

  3. CHECK WIRELESS DOOR LOCK CONTROL FUNCTION (STANDARD OPERATION FUNCTION)

    Tech Tips

    Use the following standardized test procedure to check the transmitter again.


    1. Hold the transmitter approximately 1 m (3.28 ft.) from the driver side door outside handle. The transmitter must be parallel to the ground and perpendicular to the side of the vehicle.

    2. Press and hold either the LOCK or UNLOCK transmitter switch for 1 second, and check that the doors lock or unlock, respectively.

      OK
      Doors can be locked and unlocked with transmitter switches (see page Click here).

    NG

    CHECK ROOM NO. 1 LIGHT ASSEMBLY Click here

    OK

    REPLACE DOOR CONTROL TRANSMITTER MODULE

  4. REPLACE TRANSMITTER BATTERY


    1. After replacing the transmitter battery Click here, check that the doors can be locked and unlocked using the transmitter switches.

      OK
      Doors can be locked and unlocked with transmitter (see page Click here).

    NG

    REPLACE DOOR CONTROL TRANSMITTER MODULE

    OK

    END (TRANSMITTER BATTERY DEFECTIVE)

  5. CHECK ROOM NO. 1 LIGHT ASSEMBLY


    1. Check that the room No. 1 light illumination operates normally.

      OK
      Room No. 1 light illumination operates normally.

    NG

    GO TO LIGHTING SYSTEM

    OK

  6. SWITCH TO SELF-DIAGNOSTIC MODE


    1. Switch to self-diagnostic mode by operating the ignition key cylinder.


      1. Make sure the vehicle is in its initial condition Click here. 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 9 times: turn the ignition switch ON and OFF.

        Note

        If the change to self-diagnostic mode has failed, the system will return to normal mode.

        Tech Tips


        • Turning the ignition switch ON after the above operations have been completed will end self-diagnostic mode.

        • Do not lock or unlock doors during self-diagnostic mode.

    2. A01J37TE07

      Check that the system has switched to self-diagnostic mode by checking the room No. 1 light flash pattern.

      OK
      Flash pattern should be same as illustration.

    NG

    OK

  7. CHECK BY SELF-DIAGNOSTIC MODE


    1. 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 No. 1 light.

      A01J69KE01
      Result:
      Result Proceed to
      Unmatching recognition code is output A
      Normal waves (light flash patterns) for LOCK and UNLOCK switches are output B
      No diagnosis outputs are present C

    B

    REPLACE INSTRUMENT PANEL JUNCTION BLOCK

    C

    A

  8. REGISTER RECOGNITION CODE


    1. Check that the system can be switched to rewrite mode or add mode, and that a recognition code can be registered.

      OK
      Recognition code can be registered.

    NG

    REPLACE DOOR CONTROL TRANSMITTER MODULE Click here

    OK

    END

  9. CHECK RESPONSE OF DOOR CONTROL RECEIVER


    1. When a new or normally functioning door lock control transmitter switch for the same type vehicle is held down, check that an unmatching recognition code is output.

      OK
      Unmatching recognition code is output.

    OK

    REPLACE DOOR CONTROL TRANSMITTER MODULE
