Engine Control Module Programming and Setup GAS
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:
| • | 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 a scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was replaced. |
ECM Reprogramming
Important: DO NOT reprogram a FlexFuel (E85) vehicle while the fuel composition learn function is active. If necessary, drive the vehicle until the scan tool indicates that the fuel composition learn parameter is inactive. Programming
with the fuel composition learn active will result in fuel trim DTCs.
| • | 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 a scan tool to reset the Transmission Fluid 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.
| • | Any engine repair that disturbs the crankshaft position (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. |
