Normal Operation
The anti-theft alarm inhibit grounds the smart junction box (SJB) through the switch allowing entry without setting off the alarm. The switch must operate before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.

Possible Causes
- circuit 570 (BK/WH) open
- circuit 1316 (WH/VT) open or short to power
- circuit 1317 (DB/LG) open or short to power
- driver door lock actuator
- SJB
