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 | -- |
When the Content Theft Deterrent (CTD) system arms and enables the intrusion sensor, the body control module (BCM) receives a power-up acknowledgement from the intrusion sensor via the intrusion sensor armed signal circuit.
• | CTD System is armed. |
• | Intrusion sensor is enabled. |
The BCM does not receive the power-up acknowledgement from the intrusion sensor.
The BCM will ignore all inputs from the intrusion sensor for the remainder of the CTD System arming cycle.
A current DTC will clear when the BCM receives a power-up acknowledgement from the intrusion sensor during the next CTD system arming cycle.

⇒ | If the test lamp illuminates, test the signal circuit for a short to ground. |
⇒ | If greater than the specified range, test the signal circuit for an open/high resistance. |
⇒ | If the test lamp illuminates, test the signal circuit for a short to B+. |
