Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Replace and Program ECM
To program a replacement engine control module (ECM), perform the following procedure:
- Install EL-49642 SPS Programming Support Tool.
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select ECM Control Module-Programming and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select ECM Control Module-Setup and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select ECM Control Module-Configuration and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select ECM Function-Learn/Setup and follow the on-screen instructions.
- At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
- With a scan tool, perform the Theft Deterrent Programming-Refer to Immobilizer System Component Programming (without BTM) , Immobilizer System Component Programming (with BTM) .
- With a scan tool, perform the Clutch Pedal Position Sensor Learn, if applicable-Refer to Clutch Pedal Position Sensor Learn .
- With a scan tool, perform the CKP System Variation Learn-Refer to the following:
- Crankshaft Position System Variation Learn for the 1.4L engine
- Crankshaft Position System Variation Learn for the 1.6L or 1.8L engine
- With a scan tool, perform the Throttle/Idle Learn procedure-Refer to the following:
- Throttle/Idle Learn for the 1.4L engine
- Throttle/Idle Learn for the 1.6L or 1.8L engine
- With a scan tool, perform the 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.
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.
