10-Minute Relearn Procedure

WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

When performing the 10-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure.
Use only a master key when performing the first relearn procedure. If you a valet key is used first, the TDM will not allow additional keys to be learned.

Use this procedure after replacing any of the following components:

The vehicle keys
The theft deterrent module (TDM)
The engine control module (ECM)

IMPORTANT: When replacing either the vehicle keys, PCM, or TDM and the 10-Minute Relearn Procedure is used, ensure that the appropriate calibration is selected for the replacement component on the calibration selection screen of the service programming system. The appropriate calibrations for specific vehicle theft deterrent (VTD) system components are described below.

When preparing a TDM for replacement, the Prepare Module For TDM Setup Procedure calibration is required. This allows the retrieval of required information from the TDM prior to its replacement.
When learning vehicle keys and the 10-Minute Relearn Procedure is used, the Vehicle Theft Deterrent Learn For Learning Replacement Keys calibration is required. This clears all previously learned keys from the TDM and enables the TDM to learn new vehicle keys. For learning additional vehicle keys, refer to Adding Keys .
When replacing a TDM or ECM and the 10-Minute Relearn Procedure is used, the VTD Learn for Powertrain calibration is required. This clears the previously learned fuel continue password in the ECM and enables the ECM to learn the fuel continue password of the new TDM.

IMPORTANT: When replacing a TDM with a GM SPO Replacement Part, insure the Setup a New TDM procedure is performed prior to the 10-Minute Relearn Procedure.

Connect a scan tool to the vehicle.
Turn ON the ignition, with the engine OFF.
Ensure that all power consuming devices are turned OFF on the vehicle.
With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions.
Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions. Ensure the correct programming procedure is selected based on the component being replaced or programmed. See Important above.
Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
With a master vehicle key, turn ON the ignition, with the engine OFF.
With a scan tool, select Program ECU under Service Programming System.
At this point the scan tool must remain connected for the duration of the 10-Minute Relearn Procedure.

IMPORTANT:

The scan tool will initially display 12 Minutes. The first 2 minutes allow the scan tool to initialize the appropriate control module. The remaining 10 minutes is the relearn timer.
On some vehicles the security indicator may be illuminated on steady for the duration of the 10-Minute Relearn Procedure.

Observe the scan tool. After approximately 10 minutes, the scan tool will display Programming Successful, Turn OFF Ignition. The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to CRANK.
Turn OFF the ignition and wait 5 seconds.
With a master vehicle key, start the vehicle. The TDM has now learned the key transponder information and/or the ECM has now learned the fuel continue password.
If additional keys are required to be learned, refer to Adding Keys .
With a scan tool, clear any DTCs.
