Engine Control Module Programming and Setup

Engine Control Module Programming and Setup

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. The ECM Reprogramming-Refer to Service Programming System (SPS) (Programming and Relearning) Service Programming System (SPS).
2. The CKP System Variation Learn-Refer to Crankshaft Position System Variation Learn (Programming and Relearning) Crankshaft Position System Variation Learn for the 4.6L engine or Crankshaft Position System Variation Learn (Programming and Relearning) for the 3.8L engine.
3. Engine Oil Life Remaining-When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was replaced.
4. Transmission Fluid Life Remaining-When available, use the scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was replaced.
5. Theft Deterrent-Refer to Immobilizer System Component Programming (Programming and Relearning) Immobilizer System Component Programming.

ECM Reprogramming

* If the ECM needs to be reprogrammed, Refer to Service Programming System (SPS) (Programming and Relearning) Service Programming System (SPS).
* Engine Oil Life Remaining-When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.
* Transmission Fluid Life Remaining-When available, use the scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was replaced.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, a Crankshaft Position System Variation Learn (Programming and Relearning) Crankshaft Position System Variation Learn for the 4.6L engine or Crankshaft Position System Variation Learn (Programming and Relearning) for the 3.8L engine must be performed.

* Engine replacement
* Any engine repair that disturbs the crankshaft position (CKP) sensor or its relationship with the crankshaft reluctor wheel
* CKP sensor
