Programming The 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. Record the flash part number in the original PCM.
2. Have the vehicle Personal Identification Number (PIN) available.
3. Replace the PCM.
4. Connect a battery charger to the vehicle.
5. Connect the diagnostic scan tool.
6. Position the ignition to the RUN.
7. Manually enter the Vehicle Identification Number (VIN) in diagnostic scan tool to identify what vehicle you are working on.
8. When the diagnostic scan tool successfully identifies the vehicle, locate the correct Flash. Flash the PCM software. Follow the diagnostic scan tool prompts. Cycle the ignition as directed.
9. If required, 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. If PROXI Alignment is required, Manually enter the VIN into the PCM using the "Check PCM VIN" misc function under PCM.
10. Navigate to the BCM "Misc Functions  " menu and perform the "Transfer Secret Key to ESL ECM" routine. Enter PIN when requested.
11. Verify that the engine starts and runs.
12. Select the PCM view and then select the "Misc Functions  " menu.
13. In the PCM "Misc Functions  " menu, select and run the "Learn ETC  " routine. This routine is necessary to learn the throttle position voltages and the accelerator pedal position. Follow the prompts shown on the diagnostic scan tool.
14. In the PCM "Misc Functions  " menu, perform the "Cruise Control Learn  " routine. Follow the prompts shown on the diagnostic scan tool.
15. Module programming is now complete.
