Theft Deterrent Control Module Programming and Setup

Theft Deterrent Module (TDM) Programming Using Existing Keys

Important:

* Use this procedure only if replacing the theft deterrent module (TDM) using the existing vehicle keys.

* Because of how vehicle key information and theft deterrent passwords are stored within the TDM, the Theft Deterrent Control Module Programming and Setup procedure must be performed prior to the removal and replacement of the TDM if the vehicle keys are being reused. Performing this procedure first allows the scan tool to extract the key information and passwords from the old TDM prior to its removal. Failure to perform this step will result in the failure to learn the existing vehicle keys and new vehicle keys will be required when replacing the TDM.

* Do not use the scan tool for any other programming operations while performing this procedure. Doing so will erase the stored data retrieved from the original TDM and cause the set-up to fail.

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. Select the Prepare Module for TDM Setup calibration file.
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. 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.

10. With the scan tool, select TDM in the Vehicle Control Systems Module Replacement/Setup data list.
11. Select Step 1.
12. Select Use Existing Keys.
13. Follow the scan tool on-screen instructions. The scan tool will then display Replace Module Per Service Data. At this time, replace the theft deterrent module (TDM). Refer to Theft Deterrent Module Replacement.
14. After the new TDM has been installed, using the scan tool, select Step 2 and follow the on-screen instructions. Once this has been completed, turn the ignition OFF.
15. Turn ON the ignition, with the engine OFF.
16. Ensure that all power consuming devices are turned OFF on the vehicle.
17. With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions.
18. Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
19. On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions. Select the VTD Learn for LE5 or LZ9 Powertrain System calibration or the VTD Learn for LNF Powertrain System calibration based on which engine RPO the vehicle is equipped with.
20. Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
21. With a master vehicle key, turn ON the ignition, with the engine OFF.
22. With a scan tool, select Program ECU under Service Programming System.
23. 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 fuel continue password on the next ignition switch transition from OFF to CRANK.

24. Turn OFF the ignition and wait 5 seconds.
25. With a master vehicle key, start the vehicle. The ECM has now learned the new fuel continue password.
26. If additional keys are required to be learned, refer to Adding Keys.
27. With a scan tool, clear any DTCs. Theft Deterrent Module (TDM) Programming Using New Keys
