What Does the B1271 Code Mean?

When the radio is initially installed in the vehicle, the radio receives Vehicle Identification Number (VIN) information via serial data. The radio stores a portion of the VIN and compares this sequence to the VIN information received each time the radio powers on. The VIN in the radio is a single one-time learn.
The radio theft deterrent system is intended to disable or limit radio functionality if incorrect vehicle information is received by radio. The radio disables functionality if the VIN information received by the radio does not match the VIN information that has been learned by the radio. This Diagnostic Trouble Code (DTC) is generated by the module when the Theft Protection is activated.
The DTC will be set when the radio receives the correct VIN information via serial data.
