Theft Deterrent System Frequency Code Programming

WARNING: This page is about a different car, the 2005 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

This vehicle is equipped with a theft deterrent system which interfaces with the engine control module (ECM). If the ECM is replaced, program the new ECM with the frequency code of the theft deterrent module that is currently on the vehicle. The vehicle will not start until this procedure is completed.
