Inspection Procedure

1. Check that the wireless door lock control (See OPERATION CHECK  ).

OK: NORMAL 

NG: Go to next step 

1. Check that the transmitter LED illuminates 3 times when the switch is pressed 3 times.

   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.
   NOTE: Standardized test procedure: press the transmitter switch for 1 second, directing the transmitter to 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.

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.

   OK: 

   Doors can be locked and unlocked with transmitter. 

NG: REPLACE DOOR CONTROL TRANSMITTER 

OK: NORMAL 

1. Check that the room light illuminates.

   HINT:

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

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, and 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. Then turn the ignition switch ON and OFF.
   3. Within 30 seconds of turning the ignition switch ON and OFF, perform the following 9 times: turn the ignition switch ON and OFF.

      HINT:

      • Turning the ignition switch ON after performing all of the steps above 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 light to the timing chart.

   OK: 

   The flash patterns of the room light should be the same as the patterns shown in the timing chart. 

NG: Go to step  11

OK: Go to next step 

1. Check the diagnosis outputs when the door control transmitter switch is held down. The diagnosis outputs can be checked by observing the flash patterns of the room light.

   RESULT REFERENCE
   
   

   Result	Proceed to
   Unmatching recognition code is output	A
   Normal waves of LOCK, UNLOCK and PANIC switches are output	B
   There are no diagnosis outputs (room light is OFF)	C

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.

   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.

   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.

   OK: 

   Doors can be locked and unlocked with transmitter. 

NG: Go to step  17

OK: END
