Programming Theft Deterrent System Components Scan 100

       Important: The immobilizer cartridge software is included with the Tech 2. Tech 2 users will not be required to use immobilizer data cartridge during this step. Reprogram the identification (ID) code in the following situations:

    • An immobilizer control unit has been replaced.
    • An electronic control module (ECM) has been replaced.

Reprogramming Procedure
  1. Turn the ignition OFF. Reprogramming is not allowed while the engine is running.
  2. Insert the immobilizer control unit cartridge into the scan tool.
  3. Do not start the vehicle, but turn the ignition ON.
  4. Enter the 4-digit password that enables service personnel to use the scan tool for ID code reprogramming.
  5. Use the scan tool to command RESET ID CODE.
  6. Turn the ignition OFF and ON again, but do not crank or start the engine. The ECM will reset the ECM ID code to match the new ID code that was calculated and sent by the immobilizer control unit when the ignition was first turned ON after the reset command.
  7. Return the system to the normal mode.
  8. Turn OFF the ignition.
  9. Turn ON the ignition.
  10. Start the engine.

After reprogramming the ID code, the scan tool SYSTEM DIAGNOSIS command can verify that the ECM ID code matches the immobilizer control unit ID code.

If the reprogramming procedure does not result in matching ID codes, check the electrical connectors for the serial data wire between the immobilizer control unit and the ECM.
