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 alarm module checks for a valid calibration data set, if no valid calibration data 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

The object alarm module is not programmed.


Action Taken When the DTC Sets

* The object alarm module commands red LED ON.
* 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 100 malfunction-free ignition cycles.
