PINPOINT TEST C: ALL DOOR LOCKS ARE INOPERATIVE - FROM THE DRIVER DOOR LOCK CONTROL SWITCH


Test C1-C4:






Test C5-C8:






Normal Operation
The driver door lock control switch supplies a ground signal to the driver door module (DDM). When the DDM receives ground through circuit 8-AA10 (WH/BK), the DDM sends a message through the SCP network to the rear electronic module (REM) which locks the passenger doors. At the same time the DDM locks the driver door. When the DDM receives ground through circuit 8-AA11 (WH/VT), the DDM sends a message through the SCP network to the REM which unlocks the passenger doors. At the same time the DDM unlocks the driver door.

Possible Causes
- DTC B1309 power door lock circuit short to ground
- DTC B1341 power door unlock circuit short to ground
- circuit 8-AA10 (WH/BK) shorted to ground or open
- circuit 8-AA11 (WH/VT) shorted to ground or open
