DTC Descriptor

DTC B1008 42
- Calibration Data Not Programmed

Circuit/System Description

When the ignition is turned ON, the object alarm module performs a self test to verify if any critical malfunction exists within the system. When the object alarm system has completed the power-up mode, the object alarm module establishes communication with the body control module (BCM). During the power-up mode the object detection module checks for a valid calibration data set, if no valid calibration set is found, the object alarm module disables the system and commands the red indicator ON.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

When the calibration data set is not programmed in the object alarm module upon startup.

Action Taken When the DTC Sets

* 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 sounds.

Conditions for Clearing the DTC

* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The history DTC clears after 40 malfunction-free warm-up cycles.

Circuit/System Testing

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

If DTC B1008 is current, perform the programming and setup procedure for the front or rear object alarm module.
