DTC Descriptor
DTC B1008 42
- Calibration Data Not Programmed Calibration Data Set 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. During the power-up mode, the object alarm module checks for a valid calibration data set.

Conditions for Running the DTC

* DTC B1325 is not set
* Ignition voltage is between 9-16 volts

Conditions for Setting the DTC

A valid calibration is not detected upon module power-up.

Action Taken When the DTC Sets

* Parking assist is disabled.
* The object alarm module commands the red indicator ON.
* The object alarm module sends a serial data message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message in the driver information center (DIC) and a chime will sound.

Conditions for Clearing

* The DTC will transition to history when the fault is no longer present.
* A history DTC will clear after 100 malfunction-free ignition cycles.
