DTC Descriptor
DTC B1015 00
- Vehicle Identification Number (VIN) Information Error
Circuit/System Description
When the ignition is turned ON, the rear object sensor control module receives the vehicle identification number (VIN) from the body control
module (BCM). The rear object sensor control 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 rear object sensor control module does not match the received VIN.
Action Taken When the DTC Sets
* The parking assist system is disabled.
* The rear object sensor control module sends a serial data message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST
message in the driver information center (DIC).
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.
