10-Minute Immobilizer Relearn

This 10-minute relearn procedure will relearn the prerelease password XXX the challenge/response data between the theft deterrent module (TDM) and the engine control module (ECM).

Connect a scan tool to the vehicle in the pass-thru arrangement. Turn ON the ignition, with the engine OFF. Ensure that all power consuming devices are turned OFF on the vehicle. On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the 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, ECM, or PK3 Replaced selection. 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.

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 2 minutes. 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 pre-release password XXX the challenge/response data. With a scan tool, clear any DTCs.

No only option is to tear down until you find defective part.Doug
