Without SPS Tool (30 minute Learn)
WARNING: This page is about a different car, the 2010 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
This 30 minute relearn procedure will relearn the fuel continue password between the theft deterrent module (TDM) and the engine control module (ECM).
Use this procedure after replacing any of the following components:
- The theft deterrent module (TDM)
- The powertrain control module (PCM)
NOTE:
- This procedure is not available on vehicles equipped with EXPORT configured TDMs.
- When performing the 30-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure.
- When replacing a TDM with a GM SPO Replacement Part, ensure the procedure to setup a new TDM is performed prior to the 30-Minute Relearn Procedure.
- With a new, unlearned, vehicle key, turn ON the ignition, with the engine OFF.
- Observe the security indicator. After approximately 10 minutes, the telltale will turn OFF.
- Turn OFF the ignition, and wait 5 seconds.
- Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
- Start the vehicle. The ECM has learned the fuel continue password.
- If additional keys are required to be learned, refer to Adding Keys .
- With a scan tool, clear any DTCs.
NOTE:
The engine controller learns the fuel continue password on the ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.
