WIRELESS DOOR LOCK CONTROL SYSTEM (for Sedan) - 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).

END (TRANSMITTER BATTERY DEFECTIVE)

5.CHECK NO. 1 ROOM LIGHT ASSEMBLY
  1. Check that the No. 1 room light illumination operates normally.

    OK:
    No. 1 room 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. 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:
      1. Turning the ignition switch ON after the above operations have been completed ends self-diagnostic mode.
      2. Do not lock or unlock doors during self-diagnostic mode.
