10-Minute Relearn Procedure

Use this procedure after replacing any of the following components:

• The PASS-Key III plus keys
• The theft deterrent module (TDM)
• The powertrain control module (PCM)

IMPORTANT: When replacing either the PASS-Key III plus 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 replacing existing PASS-Key III plus keys and the 10-Minute Relearn Procedure is used, or when relearning existing PASS-Key III plus keys to the existing TDM 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 PASS-Key III plus keys. For learning additional PASS-Key III plus keys, refer to Adding Keys (Domestic)  or Adding Keys (Export including Canada) .
• When replacing a PCM that has previously learned another vehicle TDM fuel continue password and the 10-Minute Relearn Procedure is used, the VTD Learn for L61 or VTD Learn for LX9 calibration is required. This clears the previously learned fuel continue password in the PCM and enables the PCM to learn the next fuel continue password it receives.
• When replacing a TDM and the 10-Minute Relearn Procedure is used, the VTD Learn for L61 or VTD Learn for LX9 calibration is required. This clears the previously learned fuel continue password in the PCM and enables the PCM to learn the next fuel continue password it receives.
IMPORTANT: When replacing a TDM with a GM SPO Replacement Part, insure the procedure to setup a new TDM is performed prior to the 10-Minute Relearn Procedure.
1. Connect a scan tool to the vehicle.
2. Turn ON the ignition, with the engine OFF.
3. Ensure that all power consuming devices are turned OFF on the vehicle.
4. With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions.
5. Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
6. 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.
7. Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
8. With a master PASS-Key III plus key, turn ON the ignition, with the engine OFF.
9. With a scan tool, select Program ECU under Service Programming System.
10. 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.
11. 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.
12. Turn OFF the ignition and wait 5 seconds.
13. With a master PASS-Key III plus key, start the vehicle. The TDM has now learned the key transponder information or the PCM has now learned the fuel continue password.
14. If additional keys are required to be learned, refer to Adding Keys (Domestic)  or Adding Keys (Export including Canada) .
15. With a scan tool, clear any DTCs.
