Check Engine Light Turns OnĪn illuminated Check Engine Light is one possible symptom of a problem with the ECM.
ECM COMPUTER DRIVER
A bad or failing ECM may produce any of the following 5 symptoms to alert the driver of a potential problem. When the ECM has any issues, it can cause all sorts of problems with the vehicle, and in some cases even render it undrivable. The ECM plays a crucial role in newer vehicles, where many of the essential functions of the car are controlled by the ECM. The ECM takes the information from the engine's various sensors and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. It essentially functions as the main computer for many of the vehicle’s engine performance and drivability functions.

If you’re experiencing any of these symptoms and suspect your ECM-power relay is in of replacement, get a diagnostic or book an ECM-power relay replacement service with a professional mechanic.The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles. If you leave it to fail completely, then you will have problems with your car running smoothly, and it may not even be able to run at all. What this means is that your battery will drain pretty quickly so you'll have either a dead or severely weakened battery.Īs soon as the ECM power-relay starts to show signs of failing you’ll want to have it checked out. If the ECM power relay is stuck in the closed position, then there is a constant flow of power being sent to the ECM. Your engine may not be able to start even when you turn the key. This can happen if the relay is stuck in the open position. The engine may not be able to turn over even when your ignition is on. Your Check Engine Light may come on due to the fact the engine isn't running as it should. Here are some signs that your ECM power relay may be on its last legs and need replacing. You won't be able to leave the part as is since your vehicle needs the ECM power relay in order to run. If it does, it's usually due to moisture issues or a power distribution issue. Although the ECM power relay is meant to last the entire lifetime of your vehicle, sometimes it can still fail.
Each time you turn your key in the ignition, the relay for the ECM is powered and turns on the actual ECM. In order for the ECM to work it needs power, which is where the ECM power relay comes into play. Basically it’s watching over all kinds of things. It monitors all kinds of information, makes the necessary adjustments to such things as injection systems, fuel supply, how power is distributing, the exhaust system, the timing of the engine, the ignition system, emissions, and more. The ECM stands for "engine control module", and just as you may suspect it is responsible for controlling the functions of the engine.
The ECM-power relay is an excellent example of these technological advancements.
It seems more and more parts rely on computers and sensors than ever before. As technology continues to advance and move forward, so does the way our vehicles operate and run.
