PINPOINT TEST K: THE ANTI-THEFT SYSTEM DOES NOT OPERATE CORRECTLY - ANTI-THEFT ALARM HORN CONTINUOUSLY ON

Test K1-K2:

Normal Operation
When the system is armed the door ajar, hood ajar and liftgate ajar switches are monitored by the smart junction box (SJB). If the SJB detects an opening of any of these entry points, without a disarm order or the ignition is cycled to RUN without the powertrain control module (PCM) seeing a valid passive anti-theft system (PATS) key, the SJB supplies power to the anti-theft alarm horn as an audible intrusion warning.

Possible Causes
- SJB
- circuit 1324 (BK/LG) shorted to power
