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

  • A Engine 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.

Perform the following steps and/or routines to program the PCM: 

  1. PCM/ECM Replaced
  2. Enable / Disable Vehicle Features - Need to enable features
  3. Set MAX vehicle speed
  4. Set MAX cruise speed
  5. Idle shutdown timer

For 2013 and newer vehicles: Also perform these additional routines (where applicable):

  1. Oil Change Monitor Type

  3. Dual Alternator Enable/Disable
  4. Dual Fuel Tank Enable/Disable (2014 and newer)
  5. Enable/Disable PTO Types
  6. PTO Single Speed RPM

Due to the PCM/TCM programming procedure, a DTC may be set in other ECUs within the vehicle. Some DTCs may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
