Pinpoint Test D: All Door Locks Are Inoperative From One Switch - Without Memory

Refer to Wiring Diagram Set 117, Remote Keyless Entry and Alarm for schematic and connector information. Diagrams By Number

Normal Operation

The Smart Junction Box (SJB) sends voltage signals to the door lock control switches through the lock and unlock input circuits. When the lock or unlock switch is pressed, the corresponding voltage signal is routed to ground, signalling the SJB (Smart Junction Box) to lock or unlock the doors. The door lock control switches have a dedicated ground circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Door lock control switch
