Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
B+ | B3089 | B3089 | -- | -- |
Intrusion Sensor Armed Signal | B3089 | B3089 | B3089 | -- |
Intrusion Sensor Alarm Signal | B3089 | B3089 | B3089 | -- |
The intrusion sensor detects movement within the vehicle while parked. B+ is supplied to the intrusion sensor at all times and the body control module (BCM) arms the sensor using the intrusion sensor armed signal circuit. If movement is detected while armed, BCM is informed via the intrusion sensor alarm on signal circuit. The BCM will then sound the content theft alarm.
