The content theft deterrent intrusion/inclination sensor is a multifunction sensor which detects motion inside the vehicle (intrusion), as well as

change in the vehicle level (inclination). The intrusion/inclination sensor is supplied power and ground for operation and communicates with the

body control module (BCM) via a dedicated LAN circuit. The sensor may be turned on or off using the disable switch and will display its status

through the status LED.

Conditions for Running the DTC

* The ignition is OFF.

* The vehicle is in Park.

Conditions for Setting the DTC

The BCM detects a malfunction within the content theft sensor.

Action Taken When the DTC Sets

The intrusion and inclination output is disabled.

Conditions for Clearing the DTC

* A current DTC is cleared when the conditions for setting the DTC are no longer present.

* A history DTC will clear after 40 malfunction-free ignition cycles.

Circuit/System Verification

Verify that DTC B291B 39 or B291B 42 is not set.

If the DTC is set, program the K9 BCM. If the DTC resets, replace the B67 ultrasonic intrusion sensor.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the S43 ultrasonic intrusion sensor disable switch.

2. Test for less than 10ohm between the ground circuit terminal 2 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition OFF, connect the harness connector at the S43 ultrasonic intrusion sensor disable switch. Disconnect the harness connector at the

B67 ultrasonic intrusion sensor.

4. Test for less than 10ohm between the ground circuit terminal 5 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
