However, there are then some services you will need in terms of maintaining your vehicle from a functional point of view and, unfortunately, when your vehicle breaks down too. Sometimes, your ECU will be at the center of this. 

ECU stands for engine control unit. It can also be referred to as PCM, powertrain control module. It ensures optimum engine performance via controlling a series of actuators on an internal combustion engine. In basic terms, it is essentially a little computer that communications with the engine to control everything from ignition timing, to torque, to how much fuel to pump, to horse power, to idle speed. When you take this into account, it is not difficult to see why the ECU is important. Now that you understand the function of it, we are going to take a look at some of the common issues and provide you with necessary details in relation to getting your ECU repaired. 

There are lots of signs that could indicate that your car has a faulty ECU. It is important to be aware of these when you take into account how necessary this component is to the proper functioning of your vehicle. One of the main signs that you have an issue with your ECU is if the engine light never turns off. Indeed there are several reasons why this could occur, yet the most common is because there is an issue with the ECU. Another common symptom is when your vehicle won’t start and there seems to be no reason for it. Check all of the other potential problems – i.e. your car battery, the starter and any other common electrical components. If these are all fine and your car still will not start, the next thing you should be considering is your vehicle’s engine control unit, as this is likely to be the issue. 

These are the two main symptoms that arise when an ECU is failing, but they are certainly not the only ones. In addition to this, if you experience unexplained drops in fuel efficiency or economy this can be connected to your engine control unit. As can poor vehicle performance. An ECU that is damaged can also cause issues when it comes to your car’s automatic transmission. Do you experience sudden jerking when you shift gears? Or any other transmission issues? If so, you should first make sure that your vehicle has an adequate amount of transmission fluid. If it does, it is worth booking an ECU computer diagnostics to check everything is working like it should be. Additional indicators include the likes of engine surges, misfires and low power.

It is important to remember that not all of the symptoms mentioned automatically mean that you have a problem with your engine control unit. It is important to consider other potential issues as well. As mentioned, your car failing to start could simply be the result of it running out of battery. Yet, if there is a problem and no other explanation seems to work, then the next step is to get an ECU diagnostics or repair booked.
