Use this procedure after replacing the following components:
- The Passkey® III (PK3) keys.
- The theft deterrent control module.
- The PCM.
NOTE:
This procedure is not available on vehicles equipped with option code (Z49 or BAE).
If replacing a theft deterrent control module with an GM SPO replacement part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.
- With a master Passkey® III key (Black), Turn ignition on, with engine off.
- Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
- Turn ignition off, and wait 5 seconds.
- Steps 1- 3 need to be repeated 2 more times for a total of 3 cycles or 30 minutes.
- With a master Passkey® III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
- With a scan tool, clear any DTCs.
NOTE:
The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK position. You must turn the ignition off before attempting to start the vehicle.
