Test D: All Door Locks Are Inoperative From One Switch
PINPOINT TEST D: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCHNormal Operation
The 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 both door lock control switches is provided through circuit GD182 (BK/GY).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch
