The Importance of an Engine Control Module
If cars had a brain, this would be its ECM or the Engine Control Module. This is likewise known as the Engine Control Unit (ECU) or the Powertrain Control Module (PCM), which is one of the most critical components that are found in modern vehicles. Such equipment acts as its main computer system for most of the engine's performance and its drivability system. The different sensors that are in the engine will relay information towards the Detroit ecm and such information is used in calculating and in tuning engine spark and fuel to get maximum efficiency and power.
Because the ECM like a caterpillar ecm is a vital part of a vehicle, if this will start to fail, your vehicle could become undrivable. If the problem arise on your car's ECM, there are some things that will help you learn about the problem if it arises.
Different Signs of Bad ECM
Illuminated Check Engine Light
The check engine light will not immediately indicate such problem with your ECM, but it will always indicates a problem with the engine. Also, this light could be triggered if there are no problems present, but doing a simple test will help determine what error codes are thrown at. The mechanic will tell you whether there's a problem with the ECM or another component.
Engine Misfiring and Stalling
An erratic behavior with the engine is also a symptom of having a bad ECM. faulty computers can also be the one responsible for engine stalling or misfiring, though it is usually more intermittent. Such symptoms also come and go and it may appear not having patterns on its severity or its frequency.
Problems on Engine Performance
If the ECM is failing, this will throw off its timing on its fuel settings or its engine. You probably have noticed unexplained drops on your fuel efficiency or feel that your vehicle is having problems on shifting. Sudden changes on the performance of your vehicle is considered to be the reason to determine the problem.
Vehicle Won't Start
Another common problem of having a ECM would be where your vehicle won't start or is having problem starting. When the ECM fails, your car will not have any engine management control system and will not start.
If you ever suspect that the ECM is the problem, it is best that you have it checked by the right professional. Being able to deal with the problem early will help you in saving a lot of money and avoiding stress.
