NOTE:  Before troubleshooting, check the B-CAN DTCs. If any DTC is indicated, troubleshoot the indicated DTC first.

1. Determine possible failure area (body control module, others)

   -1. With interior light switch: Turn the interior light switch to the DOOR position and ceiling light switch to the MIDDLE position.

   -2. Without interior light switch: Turn the ceiling light switch to the MIDDLE position.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   Do the individual map lights and door indicators come on when the door is open, and go off when the door is closed?

   YES 

   Replace the body control module .

   NO 

   Go to step 2.

2. Open wire check (FL DOOR SW, FR DOOR SW, RL DOOR SW, RR DOOR SW, T/G SW lines)

   -1. Disconnect the following connectors.

   Body control module connector D (40P)Each door switch 1P connectorPower tailgate closer unit connector B (6P) (with power tailgate)Tailgate latch 4P connector (without power tailgate)

   -2. Check for continuity between test points 1 and 2 respectively.
