1. Inclination Sensor Malfunction 2. Intrusion Sensor Malfunction |
The intrusion sensor detects movement within the vehicle while parked. B+ is supplied to the inclination sensor at all times and the body control module (BCM) arms the sensor using the armed signal circuit. If movement is detected while armed, BCM is informed via the intrusion sensor alarm on circuit. The BCM will then send a signal to the rear (auxiliary) body control module (RBCM) to sound the content theft alarm.
