Engine Control Module Programming and Setup LH2

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

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

1. ECM Reprogramming--Refer to Crankshaft Position System Variation Learn.
2. The CKP System Variation Learn--Refer to Crankshaft Position System Variation Learn.
3. The Throttle Learn Procedure--Refer to Throttle Learn
4. Theft Deterrent--Refer to Immobilizer System Component Programming. 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.
5. 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.
6. 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.

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 must be performed.

If the throttle body is replaced, a Throttle Learn must be performed.

Engine Control Module Programming and Setup V6

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

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).
2. Idle Learn Procedure--Refer to Throttle Learn.
3. Theft Deterrent--Refer to Immobilizer System Component Programming. 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.

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.
