Inspection Procedure

OK: Each function of wireless door lock control system operates normally using transmitter switches (See ON-VEHICLE INSPECTION  ).

OK: END 

NG: GO TO NEXT STEP 

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: Go to step  4

OK: GO TO NEXT STEP 

HINT:

Use the following standard 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 held 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 are locked or unlocked, accordingly.

   OK: Doors can be locked and unlocked with transmitter switches. 

NG: Go to step  5

OK: REPLACE DOOR CONTROL TRANSMITTER MODULE 

1. After replacing the transmitter battery, 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 DEFECTIVE) 

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: GO TO NEXT STEP 

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

   OK: Flash pattern is same as illustration below.

NG: Go to step  11

OK: GO TO NEXT STEP 

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 No. 1 room light assembly.

   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	C

B: REPLACE MAIN BODY ECU 

C: Go to step  9

A: GO TO NEXT STEP 

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: Go to step  15

OK: END 

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 

NG: GO TO NEXT STEP 

1. After replacing the door control receiver, 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 MAIN BODY ECU 

OK: END
