DTC B1015 (Object Alarm Module)

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview)provides an overview of each diagnostic category.

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 the vehicle identification number (VIN) from the body control module (BCM). The object alarm module will compare the VIN received to the VIN stored in memory.

Conditions for Running the DTC

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

Conditions for Setting the DTC

The VIN stored in the object alarm module does not match the received VIN.

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.

Circuit/System Verification

Verify that DTC B1015 is not set.

Note: When programming the VDAAW, use a Tech 2 and CANDi module. Using the MDI to program the VDAAW will result in a failure to complete the programming operation.

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

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
