PINPOINT TEST 1: ALL DOOR LOCKS ARE INOPERATIVE - HYBRID

Normal Operation

The smart junction box (SJB) fuse 17 (20A) provides voltage for the power lock/unlock system. Ground for the power lock/unlock system is provided to the SJB through circuit (B/GY). The SJB contains internal relays that are energized depending on input received.When the SJB receives a lock request from a door lock control switch, the SJB provides power to the door lock actuators through circuit (GY/BR). Ground for the left front door lock actuator is provided through circuit (L/G) and ground for the remaining door lock actuators is provided through circuit (V/GY). When the SJB receives an unlock request, power and ground are reversed on the previously listed circuits.

Possible Causes
- Fuse
- Wiring, terminals or connectors
- SJB

Diagnostic Procedure
