Test D5-D8:

Normal Operation
The passenger door lock control switch supplies a ground signal to the rear electronic module (REM). When the REM receives ground through circuit 8-AA20 (WH/BU), the REM locks the passenger doors and sends an SCP message to the driver door module (DDM) to lock the driver door. When the REM receives ground through circuit 8-AA21 (WH/GN), the REM unlocks the passenger doors and sends an SCP message to the DDM to unlock the driver door.

Possible Causes
- DTC 1300, power door lock circuit failure
- DTC 1310 power door unlock circuit failure
- circuit 8-AA20 (WH/BU) open
- circuit 8-AA21 (WH/GN) open
