Immobilizer System Component Programming North America, except Canada

This 10-minute relearn procedure will relearn the fuel enable password between the body control module (BCM) and the engine control module/powertrain control module (ECM/PCM).

1. Connect a scan tool to the vehicle in the pass-thru arrangement.
2. Turn ON the ignition, with the engine OFF.
3. Ensure that all power consuming devices are turned OFF on the vehicle.
4. On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the Legacy Pass-Thru method. Ensure the correct programming selection is chosen based on component being replaced or programmed. For this procedure, go to the V.T.D. Vehicle Theft Deterrent Learn menu and choose the Vehicle Theft Deterrent Learn for Domestic Vehicles selection.
5. 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 for the duration of the 10-minute relearn procedure.

6. 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 password on the next ignition switch transition from OFF to CRANK.
7. Turn OFF the ignition and wait 2 minutes.
8. Turn the ignition to the RUN position for 15 seconds, then start the vehicle. The ECM/PCM has now relearned the fuel enable password.
9. With a scan tool, clear any DTCs.

This 30-minute relearn procedure will relearn the fuel enable password between the BCM and the ECM/PCM.

1. With a master vehicle key, turn ON the ignition, with the engine OFF.
2. Observe the security indicator. After approximately 10 minutes, the telltale will turn OFF.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.

Important: The vehicle learns the fuel enable passwords on the ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.

5. Start the vehicle. The vehicle has now learned the ECM/PCM has now learned the fuel enable password.
6. With a scan tool, clear any DTCs.

This 10-minute relearn procedure will relearn the fuel continue password between the theft deterrent module (TDM) and the engine control module (ECM).

1. Connect a scan tool to the vehicle in the pass-thru arrangement.
2. Turn ON the ignition, with the engine OFF.
3. Ensure that all power consuming devices are turned OFF on the vehicle.
4. On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the Legacy Pass-Thru method. Ensure the correct programming selection is chosen based on component being replaced or programmed. For this procedure, go to the V.T.D. Vehicle Theft Deterrent Learn (Export Only) menu and choose the Vehicle Theft Deterrent Learn for Powertrain System selection.
5. 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 for the duration of the 10-minute relearn procedure.

6. 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.
7. Turn OFF the ignition and wait 2 minutes.
8. With a master vehicle key, turn the ignition to the RUN position for 15 seconds, then start the vehicle. The TDM and ECM have now relearned the fuel continue password.
9. With a scan tool, clear any DTCs.
