1 49 Only Wireless Control Function is Inoperative DESCRIPTI The door control receiver receives signals from the transmitter and sends these signals to the multiplex network body ECU. The multiplex network body ECU then controls the door operation by sending LOCK/ UNLOCK signals to the appropriate door lock actuator.

END 3 CHECK WIRELESS DOOR LOCK FUNCTIS (STNDRD OPERTI) Check standard LOCK/UNLOCK switch operation. NOTICE: Standardized test procedure: press the transmitter switch for 1 second, directing the beam at the driver side door outside handle from a distance of 1 m (3.28 ft). The transmitter should be pointed directly at the door handle, i.e. at a 90 angle to the vehicle body. NORML 4 CFIRM ROOM LIGHT Check that the room laight comes on. : Room light comes on. REPIR OR REPLCE ROOM LIGHT SSEMLY 5 SWITCH TO SELF-DIGNOSTIC MODE Switch to self-diagnostic mode by operating the ignition key cylinder. (1) Put the vehicle into its initial condition (See page -43), and insert the key into the ignition key cylinder and remove it. (2) Within 5 seconds of the key being removed (step 1), insert the key into the ignition key cylinder again (ignition key in the LOCK position). Then turn the ignition switch and return it to the LOCK position.

NOTICE: If the change to self-diagnostic mode has failed, the system returns to normal mode. HINT: Turning the ignition switch after step -(3) has been completed ends self-diagnostic mode. Do not lock or unlock any doors during selfdiagnostic mode. Check that the system has switched to self-diagnostic mode by checking the blinking frequency of the room light. : The room light output should be as shown in the timing chart on the left. a b Go to step E02 6 CHECK Y SELF-DIGNOSTIC MODE Inspect the diagnosis outputs when the door control transmitter switch is held down.
