Theft Deterrent System Programming: Notes
NOTE:
When replacing theft deterrent control module with GM Service Parts Operation (SPO) Replacement Part, module will learn keys immediately. Existing PCM must learn new fuel continue password when theft deterrent control module is replaced. When replacing PCM, new PCM will learn incoming fuel continue password immediately after programming and upon receipt of password message. Once password message is received and password is learned, perform learn procedure to change password again. A PCM from another vehicle will have learned fuel continue password of other vehicle's theft deterrent control module. Perform either 10-minute or 30-minute relearn procedure after programming to learn fuel continue password of current vehicle's theft deterrent control modules.
NOTE:
When performing either relearn procedure, all previously learned keys will be erased from theft deterrent control module's memory. Additional keys may be learned immediately after first relearn procedure by inserting additional key and turning ignition switch to RUN position within 10 seconds of removing previously learned key. Use only a master key when performing first relearn procedure. If a valet key is used first, theft deterrent control module will not allow additional keys to be learned.
