Engine Control Module Programming and Setup

Engine Control Module Programming and Setup (LH2 - Gas, 8 Cylinder, 4.6L, SFI, V8, DOHC, HO)

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. ECM Reprogramming-Refer to Crankshaft Position System Variation Learn (Service and Repair) .
2. The CKP System Variation Learn-Refer to Crankshaft Position System Variation Learn (Service and Repair) .
3. Theft Deterrent-Refer to Immobilizer System Component Programming (Programming and Relearning) . The ECM will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. An ECM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.
4. 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.
5. 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.



ECM Reprogramming

* If the ECM needs to be reprogrammed, refer to Service Programming System (SPS) (Programming and Relearning) .
* 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.



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 (Service and Repair) 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
