Engine Control Module Programming and Setup (With RPO LLY)

The following service procedures require either a programming or a setup event performed for a complete repair.

ECM Replacement

If the engine control module (ECM) is replaced, the following procedures must be performed:

1. Capture and restore the Option data.

Important: The Option data collected from the ECM that was replaced must be restored in the new ECM before programming.

2. Restore the Option data in the new ECM.

Important: Clear any DTCs that may have set after completing the programming procedure.

3. Enable ECM Reprogramming-Refer to Service Programming System (SPS). Programming and Relearning
4. Start and idle vehicle.
5. Using the scan tool, perform the Turbocharger Learn Procedure-Refer to Turbocharger Learn.
6. If necessary, preform the following:

- Theft Deterrent-Refer to Programming Immobilizer System Components. Programming and Relearning
- The Fuel Injector Flow Rate Programming-Refer to Fuel Injector Flow Rate Programming.
- Engine Oil Life Remaining-Use scan tool to reset Engine Oil Life..
- Fuel Filter Life-Use scan tool to reset Fuel Filter Life.
