Engine Control Module Programming and Setup 3.6L

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 reprogrammed, the following procedures must be performed:

  1. ECM Reprogramming--Refer to Service Programming System (SPS).
  2. Idle Learn Procedure--Refer to Idle Learn.
  3. Theft Deterrent--Refer to Theft Deterrent Control Module Programming and Setup. 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.

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 Idle Learn.

    • Throttle body assembly
    • ECM

Engine Control Module Programming and Setup LHD 6.0L Engine

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:

    Important: When replacing the ECM, the ECM must be reset prior to removal. Failure to perform this procedure will result in the inability to:

       • Test the ECM for warranty purposes.
       • Install the ECM into other vehicles.

  1. ECM reset procedure.
  2. ECM reprogramming - Refer to Service Programming System (SPS).
  3. The CKP Variation Learn/CASE - Crank Angle Sensing Error procedure - Refer to Crankshaft Position System Variation Learn.
  4. The Theft Deterrent Programming - Refer to Theft Deterrent Control Module Programming and Setup.

ECM Reprogramming

    • If the ECM needs to be reprogrammed, refer to 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.

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 CKP Variation Learn Procedure must be performed. Refer to Crankshaft Position System Variation Learn .

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

Perform the Diagnostic Repair Verification after completing the proceeding procedures.
