10-Minute Relearn Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Use only a master key when performing the first relearn procedure. If 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:

IMPORTANT: When replacing a TDM with a GM SPO Replacement Part, ensure the procedure to setup a new theft deterrent module 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 selection is chose based on component being replaced or programmed. For this procedure, choose the Vehicle Theft Deterrent menu selection.
  7. Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
  8. With a master vehicle 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.
    11. 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 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 2 minutes.
  13. With a master vehicle key, turn the ignition to the RUN position for 15 seconds, then start the vehicle. The TDM has now learned the key transponder information and the ECM has learned the fuel continue password.
  14. With a scan tool, clear any DTCs.
