Perimeter Anti-Theft Alarm - System Operation and Component Description — 2016 workshop reference 5985

Intrusion Sensor

The intrusion sensor is powered at all times and is monitored by the BCM. When the perimeter alarm is armed, the intrusion sensor monitors the passenger compartment for movement and, if movement is detected, it sends a signal to the BCM.

When the intrusion sensor is replaced, the BCM configuration must first be uploaded into a diagnostic scan tool, a new intrusion sensor installed, and then the BCM configuration downloaded back into the BCM for the new intrusion sensor to operate correctly.

Anti-Theft Alarm Horn

The anti-theft alarm horn is located behind the right rear quarter trim panel and is controlled by the BCM. When the perimeter alarm activates, the BCM energizes an internal relay to provide voltage to the anti-theft alarm horn. The anti-theft alarm horn is similar in design to a traffic horn.

BCM

The BCM controls the operation of the perimeter alarm. Based on input, the BCM arms, disarms, activates or deactivates the perimeter alarm.

The BCM requires PMI when replaced. Additionally, at least 2 keys must be programmed and the parameter reset procedure carried out.
