* 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.
