This DTC is generated by the module when the Theft Lock is activated. This occurs when the VIN as received over the data communication circuit and the VIN as stored in the module memory do not match. This also occurs when no VIN is received over the data communication circuit. The only circuit required is the communication line.

This DTC test runs when the radio changes from OFF to ON.

This DTC is generated by the module when the VIN as received over the data communication circuit and the VIN as stored in the module memory do not match. This also occurs if no VIN is received over the data communication circuit.

The radio does not function. The radio will display indicate that Theftlock is active.

Re-calibration with the correct calibrations for the vehicle and cycling the radio to OFF then to ON will clear the DTC if there is no damage to the radio.

This DTC may be an indication that an incorrect radio is installed in the vehicle, or that the radio was replaced without reprogramming with the new information.
