Engine Control Module Programming and Setup

Engine Control Module Programming and Setup (V6)

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

ECM Replacement and Reprogramming

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

1. ECM Reprogramming-Refer to Service Programming System (SPS) (Programming and Relearning).
2. Idle Learn Procedure-Refer to Throttle Learn (Programming and Relearning).
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.

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, an Idle Learn Procedure must be performed. Refer to Throttle Learn (Programming and Relearning).

* Throttle body assembly
* ECM
