DTC Descriptor
DTC B1015 00
- Vehicle Identification Number (VIN) Information Error
Diagnostic Fault Information
Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
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 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 to indicate 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.
* The VIN stored in the BCM does not match the vehicle VIN.
Action Taken When the DTC Sets
* The object alarm system is disabled.
* The object alarm module commands ON the information center telltale red indicator.
* The object alarm module will send a GMLAN 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 VIN stored in the object alarm module matches the VIN stored in the BCM.
Circuit/System Testing
1. Ignition ON, scan tool installed, verify that DTC B1015 is a history code and verify that there is no VIN mismatch with the BCM, object alarm module and the vehicle VIN.
• If any VIN mismatch exists, programme the module with the correct VIN.
