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.
- The Throttle Learn procedure--Refer to
Throttle 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
Immobilizer System Component Programming.
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. |
| | 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 |
| ⇒ | If the throttle body is replaced, a Throttle Learn procedure must be performed. Refer to
Throttle Learn. |
