Engine Control Module Programming and Setup (LF1)

Engine Control Module Programming and Setup (LF1)


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:


1. ECM Reprogramming-Refer to Service Programming System (SPS) .

2. Theft Deterrent-Refer to Immobilizer System Component Programming .

3. The CKP System Variation Learn-Refer to Crankshaft Position System Variation Learn (LF1, LFW) .

4. The Throttle/Idle Learn procedure-Refer to Throttle/Idle Learn (LF1, LFW) Throttle/Idle Learn (Without LF1, LFW) .

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.


ECM Reprogramming


• If the ECM needs to be reprogrammed, refer to Service Programming System (SPS) .

• 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.

•
Note

After programming, perform the following to avoid future misdiagnosis:


Turn the ignition OFF for 30 seconds.

• Turn the ignition to 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 (LF1, LFW) .


• Engine Replacement

• Any engine repair that disturbs the CKP sensor or its relationship with the crankshaft reluctor wheel

• CKP sensor


If the throttle body is replaced or a throttle body cleaning procedure is completed, the Throttle/Idle Learn Procedure must be performed. Refer to Throttle/Idle Learn (LF1, LFW) Throttle/Idle Learn (Without LF1, LFW) .
