Programming The CUSW Powertrain Control Module (Pcm)

This procedure is required when one or more of the following situations are true:

• A Powertrain Control Module (PCM) has been replaced.
• Diagnostic Trouble Code (DTC) P1602 - PCM Not Programmed is set.
• An updated calibration or software release is available for either the PCM or Transmission Control Module (TCM).

This procedure assumes that the scan tool is properly configured to the dealership network with either a wired or wireless connection. For help on how to network the scan tool, use the "Help" tab at the top of the diagnostic application.

Programming Procedure: 

1. Connect a battery charger to the vehicle.
2. Connect the scan tool.
3. Ignition key should be in RUN position.
4. Manually enter the VIN in wiTECH to identify what vehicle you are working on.
5. Flash the PCM software.
6. Perform the "Proxy Configuration Alignment"  located in the "Vehicle Preparations" menu in the Body Control Module (BCM). This routine will copy the PROXI into the PCM and write the PCM VIN.
7. Select and run the "PCM/ECM/ESL Replaced"  routine. Verify that the PCM states programmed after it transfers the immobilizer data.
8. Run the "Proxy Configuration Alignment"  once again to verify no misalignments.
9. Perform the "Throttle Follower"  test.
10. Erase any codes.
11. Road test the vehicle.
12. Recheck for DTCs. Correct any DTC's as needed.
13. Programming is complete.
