Engine Control Module Programming and Setup

Engine Control Module Programming and Setup

The following service procedures require either a programming or a setup event performed for a complete repair.

ECM Replacement

Warning: Replacement or reprogramming of the ECM, or replacement of the clutch pedal position sensor (CPPS) or clutch pedal requires that a CPPS learn procedure be performed. Failure to perform the CPPS learn procedure may result in personal injury or damage to the vehicle or its components if the vehicle is in gear and the starter motor is accidentally engaged.

If the engine control module (ECM) is replaced, the following procedures must be performed:

1. ECM Reprogramming - Refer to Service Programming System (SPS).
2. The CKP System Variation Learn - Refer to Crankshaft Position System Variation Learn.
3. 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.
4. 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.
5. Theft Deterrent - Refer to Programming Theft Deterrent System Components.
6. Clutch pedal, if equipped with manual transmission - Refer to Clutch Pedal Position Sensor Learn.

ECM Reprogramming

Warning: Replacement or reprogramming of the ECM, or replacement of the clutch pedal position sensor (CPPS) or clutch pedal requires that a CPPS learn procedure be performed. Failure to perform the CPPS learn procedure may result in personal injury or damage to the vehicle or its components if the vehicle is in gear and the starter motor is accidentally engaged.

- 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.

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.

- Engine replacement
- Any engine repair that disturbs the CKP sensor or its relationship with the crankshaft reluctor wheel
- CKP sensor
