Programming Theft Deterrent System Components
The Body Control Module (BCM) stores the
theft deterrent passkey code (key code) in nonvolatile memory. This key code is stored one time and cannot be changed or relearned. A new service parts BCM does not have a key code stored in memory. When a new BCM is installed in the vehicle, the BCM will learn the first key code if encounters at ignition ON and stores this code in memory. Once the BCM learns a key code, the code cannot be changed. If a BCM from another vehicle is installed, the key code stored in that BCM must be determined and a matching key obtained in order for the theft system to operate properly. Refer to the Replacing Keys procedure in order to determine the stored key code.
