Programming Theft Deterrent System Components: Notes
NOTE:
When replacing a theft deterrent control module with an GM Service Parts Operation (SPO) Replacement Part, module will learn the keys immediately. Existing Powertrain Control Module (PCM) must learn new fuel continue password when theft deterrent control module is replaced. A Scan tool and Techline Terminal with current Service Programing System (SPS) software is needed to program theft deterrent system components.
NOTE:
When replacing a PCM with a GM SPO replacement part, new PCM will learn the incoming fuel continue password immediately after programming and upon receipt of a password message. Once a password message is received and a password is learned, perform learn procedure to change this password again. A PCM which had been installed in another vehicle will have learned the other vehicle's theft deterrent control module fuel continue password. Perform either 10-minute relearn procedure 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 the 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.
