Test D: All Door Locks Are Inoperative From One Switch

PINPOINT TEST D: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCH

Normal Operation
The smart junction box (SJB) sends voltage signals to the door lock control switches through circuits CPK19 (BU/GN) and CPK23 (YE/VT) for the lock and unlock requests, respectively. When the lock or unlock switch is pressed, the voltage signal is routed to ground. Ground for the LH door lock control switch is provided through circuit GD133 (BK). Ground for the RH door lock control switch is provided through circuit GD156 (BK/VT).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch
