Circuit/System Description

WARNING: This page is about a different car, the 2018 Buick Envision. However, it is still accessible from the selected car via links, so may be relevant.

When the Media Disc Player is initially installed in the vehicle, it receives VIN information via serial data. The Media Disc Player stores a portion of the VIN and compares this sequence to the VIN information received each time the Media Disc Player powers on. The VIN in the Media Disc Player is a single one-time learn.

The Media Disc Player theft deterrent system is intended to disable or limit Media Disc Player functionality if incorrect vehicle information is received by the Media Disc Player. The Media Disc Player disables functionality if the VIN information received by the Media Disc Player does not match the VIN information that has been learned by the Media Disc Player. This DTC is generated by the module when the Theft Protection is activated.
