Test A: All Door Locks Are Inoperative From One Switch
PINPOINT TEST A: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCHA1:
A2-A3:
Normal Operation
The smart junction box (SJB) monitors circuits 119 (PK/YE) and 120 (PK/LG) for a ground signal. If the power lock switch is pressed to unlock, circuit 120 (PK/LG) is grounded through the switch to circuit 57 (BK) and the door lock actuators receive voltage from the SJB on circuits 1015 (RD/WH) and 118 (PK/OG) causing the door lock actuators to cycle to unlock. If the power lock switch is pressed to lock, circuit 119 (PK/YE) is grounded through the switch to circuit 57 (BK) and the door lock actuators receive voltage from the SJB on circuit 117 (PK/BK) causing the door lock actuators to cycle to unlock.
Possible Causes
- circuit 57 (BK) open
- circuit 119 (PK/YE) open
- circuit 120 (PK/LG) open
- door lock control switch
