Pinpoint Test 4: All Door Locks Are Inoperative From One Switch

PINPOINT TEST 4: 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 (L/G) and (Y/V) 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 both door lock control switches is provided through circuit (B/GY).

Possible Causes
- Wiring, terminals or connectors
- Door lock control switch

Diagnostic Procedure

CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
