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:
- 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

module was reprogrammed. |
| | Important: After programming, perform the following
to avoid future misdiagnosis:
|
| • | Turn the ignition OFF for 30 seconds. |
| • | Turn the ignition ON with the engine OFF. |
| • | Use the scan tool in order to retrieve history DTCs from all modules. |
| • | Clear all history DTCs. |
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, the CKP Variation Learn Procedure
must be performed. Refer to
Crankshaft Position System Variation Learn.
| • | Any engine repair that disturbs the CKP sensor or its relationship with
the crankshaft reluctor wheel |
