Engine Control Module Programming and Setup (W/RPO LMM)

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 the Option data.

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


2. Enable ECM Reprogramming-Refer to Service Programming System (SPS) (Programming and Relearning) .
3. Restore the Option data in the new ECM.
4. Start and idle vehicle.
5. Using the scan tool, perform the Turbocharger Learn Procedure. Refer to Turbocharger Learn (Programming and Relearning) .
6. Perform a Diesel Particulate Filter (DPF) Regeneration Enable (Diesel Particulate Filter (DPF) Regeneration Enable) .
7. If necessary, perform the following:

* Theft Deterrent-Refer to Theft Deterrent Control Module Programming and Setup (Programming and Relearning) .
* The Fuel Injector Flow Rate Programming-Refer to Fuel Injector Flow Rate Programming (Service and Repair) .
* Engine Oil Life Remaining-Use scan tool to reset Engine Oil Life.
* Fuel Filter Life-Use scan tool to reset Fuel Filter Life.




ECM Reprogramming


Important: It is necessary to record Fuel Filter Life before reprogramming. The ECM reprogramming procedure will reset Fuel Filter Life to zero.


1. Record Fuel Filter Life.

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


2. Enable ECM Reprogramming-Refer to Service Programming System (SPS) (Programming and Relearning) .
3. Reset Fuel Filter Life to the recorded value.
4. Start and idle vehicle.
5. Using the scan tool, perform the Turbocharger Learn Procedure. Refer to Turbocharger Learn (Programming and Relearning) .
6. Perform a Diesel Particulate Filter (DPF) Regeneration Enable (Diesel Particulate Filter (DPF) Regeneration Enable) .
7. If necessary, perform the following:

* Theft Deterrent-Refer to Theft Deterrent Control Module Programming and Setup (Programming and Relearning) .
* The Fuel Injector Flow Rate Programming-Refer to Fuel Injector Flow Rate Programming (Service and Repair) .
* Engine Oil Life Remaining-Use scan tool to reset Engine Oil Life.
