Diagnostic Fault Information

Circuit/System Description

When the content theft deterrent (CTD) system arms and the inclination and intrusion sensors are enabled, the body control module (BCM) receives

a power-up acknowledgement from the sensors via the sensor signal circuit.

Conditions for Running the DTC

* The inclination and intrusion sensors are enabled

* The CTD system has armed

Conditions for Setting the DTC

The BCM does not receive the power-up acknowledgement from the inclination and intrusion sensors

Action Taken When the DTC Sets

The BCM will ignore all inputs from the inclination and intrusion sensors for the remainder of the CTD system arming cycle

Conditions for Clearing the DTC

A current DTC will clear when the BCM receives a power-up acknowledgement during the next CTD system arming cycle

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the inclination sensor.

2. Verify a test lamp illuminates between the B+ circuit terminal 1 and ground.

瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

3. Disconnect the harness connector at the intrusion sensor.

4. Verify a test lamp illuminates between the B+ circuit terminal A and ground.

瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

5. Ignition OFF, disconnect the harness connector at the intrusion sensor.

6. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal A and ground.

瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
