Test A: All Door Locks Are Inoperative

PINPOINT TEST A: ALL DOOR LOCKS ARE INOPERATIVE

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 GD133 (BK). The SJB contains internal relays that are energized depending on input received.

When the SJB receives a lock request from the door lock control switch, the SJB provides power to the door lock actuators through circuit CPL11 (GY/BN). Ground for the LH front door actuator is provided through circuit CPL51 (BU/GN) and ground for the remaining door lock actuators is provided through circuit CPL52 (VT/GY). When the SJB receives an unlock request, power and ground are reversed on the previously listed circuits.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Luggage compartment lid latch
- SJB
