Engine Control Module (ECM) Replacement
How are ECM issues diagnosed?
When the ECM is suspected of failure, the mechanic will have to look up the computer's technical specifications and compare them to the actual readings to specified readings. Other causes for a specific symptom will also have to be ruled out.
How is the ECM replaced?
Replacing the ECM is normally easy, since the computer first has to be accessed for diagnostic testing. In most vehicles, the ECM is in the engine bay, but a few manufacturers place the ECM inside the vehicle. If the ECM fails diagnostic testing, it will be unplugged and replaced.
RepairPal recommendations for ECM issues
The battery connects directly to the engine, meaning it's grounded to the same point as many engine sensors. So, if the battery is incorrectly installed in a vehicle, the ECM can be destroyed, along with some sensors and wiring.
Electrical diagnostics can be tricky, and there are many variables to account for. When electrical problems arise, diagnostics may take several hours to complete, or just a few minutes. The longer it takes, the higher the cost of repairs.
Choosing a facility with proper equipment and training for their staff may significantly reduce the diagnostic time needed. RepairPal makes sure its certified shops have this equipment and training.
Can I replace the ECM myself?
Diagnosis and calibration are the trickiest parts of dealing with a faulty ECM. If you have experience with these types of computers, and have access to the correct specifications for the ECM, replacement can be fairly easy. Otherwise, this repair is best left to a professional.
