   1. OK: Transmitter LED illuminates 3 times when the switch is pressed 3 times. 

NG: Go to step   4 

OK: Go to next step 

1. Check standard LOCK/UNLOCK switch operation.

NG: Go to step   5 

OK: REPLACE DOOR CONTROL TRANSMITTER 

1. After replacing the transmitter battery, check that the doors can be locked and unlocked by using the transmitter LOCK/UNLOCK switch.
   1. OK: Doors can be locked and unlocked with transmitter. 

NG: REPLACE DOOR CONTROL TRANSMITTER 

OK: NORMAL 

1. Check that the room lamp illuminates.

HINT:

When the room lamp does not illuminate, proceed to self-diagnostic mode after repairing the room lamp.

NEXT: Go to next step 

1. Switch to self-diagnostic mode by operating the ignition switch.
   1. Make sure the vehicle is in a condition where wireless control functions can be operated (See WIRELESS DOOR LOCK CONTROL SYSTEM ), insert the key into the ignition key cylinder and remove it.
   2. Within 5 seconds of removing the key (step ( 1)), insert the key into the ignition key cylinder. Then turn the ignition switch ON and OFF.
   3. Within 30 seconds of turning the ignition switch OFF again (step ( 2)), perform the following 9 times: turn the ignition switch ON and OFF.

   HINT:

   • Turning the ignition switch ON after step ( 3) has been completed will end self-diagnostic mode.
   • Do not lock or unlock doors during self-diagnostic mode.
   NOTE: If the change to the self-diagnostic mode has failed, the system will return to normal mode.
2. Check that the system has switched to self-diagnostic mode by comparing the flash patterns of the room lamp to the timing chart on the left.

   OK: 

   1. Room lamp and timing chart have same flash patterns.

Result: 

B: Go to step   17 

C: Go to step   9 

A: Go to next step 

1. Check that the system can switch to rewrite mode or add mode, and that a recognition code can be registered.
   1. OK: System can switch to rewrite mode or add mode, and recognition code can be registered. 

NG: Go to step   10 

OK: NORMAL (CARRY OUT INSPECTION OF FUNCTION) 

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

NG: Go to step   14 

OK: REPLACE DOOR CONTROL TRANSMITTER 

1. After replacing the door control receiver, check that the doors can be locked and unlocked by using the transmitter LOCK/UNLOCK switch.
   1. OK: Doors can be locked and unlocked with transmitter. 

NG: Go to step   17 

OK: END
