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, signaling the SJB 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:
