Programming Verification

  1. With a scan tool, clear the DTCs.
  2. Start the engine.
  3. If the engine does not start, or the engine operates poorly, repeat the Service Programming procedure. Perform the following procedures before programming the PCM:
    • Ensure the control module and DLC connections are OK.
    • Ensure the Techline operating software is up to date.
    • Ensure the calibration part number is correct for the vehicle.
  4. Program the control module. If the control module still cannot be programmed properly, replace the control module. Refer to Powertrain Control Module (PCM) Replacement . You must program the replacement control module.
