Test E: All Door Locks Are Inoperative From One Switch - With Memory
PINPOINT TEST E: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCH - WITH MEMORYNormal Operation
The smart junction box (SJB) sends voltage signals to the passenger door lock control switch through circuits CPL42 (GY/YE) and CPL43 (VT/GY) for the lock and unlock requests, respectively. When the lock or unlock switch is pressed, the voltage signal is routed to ground.
The driver door module (DDM) sends voltage signals to the driver door lock control switch through circuits CPL42 (GY/YE) and CPL43 (VT/GY) for the lock and unlock requests, respectively. When the lock or unlock switch is pressed, the voltage signal is routed to ground.
The driver door lock control switch is grounded through circuit GD126 (BK/WH) and the passenger switch is grounded through circuit GD139 (BK/YE).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch
- DDM
- SJB
