PINPOINT TEST A: ALL DOOR LOCKS ARE INOPERATIVE

A1-A3:

Normal Operation
The smart junction box (SJB) receives voltage through circuit 37 (YE). Circuit 37 (YE) supplies voltage to the 3 internal SJB door lock relays which are part of the SJB. When the SJB receives a lock or unlock command through a door lock control switch, keyless entry keypad or RKE transmitter, it activates the door lock actuators accordingly by operating the correct SJB door lock relay(s). The SJB is grounded on circuit 1205 (BK).

Possible Causes
- Fuse
- Circuit 37 (YE) open
- Circuit 1205 (BK) open
- SJB
