DTC Descriptor

DTC B1015 00
- Vehicle Identification Number (VIN) Information Error

Circuit/System Description

When the ignition is turned ON, the object alarm module receives and stores the vehicle identification number (VIN) from the body control module (BCM). The BCM sends serial data messages to the object alarm module with the VIN information. The object alarm module will compare the VIN received to the VIN stored in memory. If the VIN stored in memory does not match the VIN transmitted by the BCM, the object alarm module sets a DTC and commands the red indicator ON indicating a system malfunction.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

The object detection module VIN digits does not match the digits stored in the BCM.

Action Taken When the DTC Sets

* The object alarm system is disabled.
* The object alarm module commands red LED ON.
* The object alarm module sends a serial data 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 VIN that is stored in the object alarm module matches the VIN stored in the BCM.
* The history DTC clears after 100 malfunction-free ignition cycles.

Circuit/System Verification

Verify that DTC B1015 is not set.

If the DTC is set, program the object alarm module. If the DTC resets, replace the object alarm module.
