Engine Control Module Programming and Setup 4.6L
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:
- The ECM Reprogramming--Refer to
Service Programming System (SPS)
.
- The CKP System Variation Learn--Refer to
Crankshaft Position System Variation Learn
.
- 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.
- 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.
- Theft Deterrent--Refer to
Programming Theft Deterrent System Components
.
ECM Reprogramming
• | 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
must be performed.
• | Any engine repair that disturbs the crankshaft position (CKP) sensor or its relationship with the crankshaft reluctor wheel |
Engine Control Module Programming and Setup 3.6L - LY7
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:
- ECM Reprogramming--Refer to
Service Programming System (SPS).
- Idle Learn Procedure--Refer to
Idle Learn in Engine Controls - 3.6L (LY7).
- Theft Deterrent--Refer to
Programming Theft Deterrent System Components in Theft Deterrent. 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.
- 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.
- 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
Idle Learn in Engine Controls - 3.6L (LY7).
Engine Control Module Programming and Setup 4.4L
The following service procedures require either a programming or a setup event performed for a complete repair.
