Circuit/System Description

When the ignition is turned ON, the object alarm detection system performs tests to diagnose critical malfunctions within the system. When the object alarm detection system has completed the power-up mode, the object alarm module will establish communication with the body control module (BCM). During the power-up mode the object alarm module will check for a valid calibration data set, if no valid calibration data set is found, the object alarm module will disable the system and command the red indicator ON.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

This code sets as a current DTC when the calibration set does not exist in the object alarm module upon startup.

Action Taken When the DTC Sets

* The object alarm module sets a DTC.
* The object alarm module commands ON the information center telltale red indicator.
* The object alarm module will send a serial data communication message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message on the driver information center (DIC) and the chime will sound.

Conditions for Clearing the DTC

* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The object alarm module receives a clear code command from the scan tool.

Circuit/System Testing

1. Ignition ON, scan tool installed, verify that DTC B1008 is a history code
