      • Review the repair history of the vehicle.
      • Make sure that the vehicle has the correct PCM/ECM and WIN installed by verifying the part numbers.
      • With the scan tool, ensure that the PCM/ECM and WIN are programmed correctly. Compare the PCM/ECM VIN to the WIN VIN and ensure the two VINs match.
    2. With the scan tool, record and erase the DTCs.
    3. Perform three ignition cycles, leaving the ignition switch on for a minimum of one minute per cycle.
    4. With the scan tool, read the active DTCs.

      • If the engine does not crank, go to  2
      • If the engine does crank, go to  2 and answer "Yes" to the question in step 2.
