Test I: A Single Door Lock Is Inoperative - LH Rear Door

PINPOINT TEST I: A SINGLE DOOR LOCK IS INOPERATIVE - LH REAR DOOR

I1-I4:

I4-I6:

Normal Operation
The driver door module (DDM) receives lock/unlock inputs from the driver door lock control switch, remote keyless entry (RKE) transmitter, or RKE keypad. The DDM sends a standard corporate protocol (SCP) message to the rear electronic module (REM) for the lock/unlock function.

The REM receives lock/unlock input from the DDM and the passenger door lock control switch. The REM then locks/unlocks the LH rear door through circuit 32-AA16 (WH/BK) and circuit 33-AA15 (YE/GN).

Possible Causes
- circuit 32-AA16 (WH/BK) short to ground or open
- circuit 33-AA15 (YE/GN) short to ground or open
- rear door latch
- REM
