Signs that Your Vehicle ECM is Faulty and How to Choose the Best ECM, TCM &ECU.
If vehicles had brains, the ECM would be the perfect fit. It is also referred to as the ECU or TCM. It is a very critical component for the vehicles. Basically, it is the main computer system for the vehicle which monitors the drivability systems as well as the performance of the engine. There are sensors in the engine which pass information to the ECM which is in turn used in calculation and tuning engine fuel and spark for all the parts to perform powerfully and efficiently. There is no way the vehicle can leave the parking lot if this part is compromised. When you know how to tell when the ECM is failing, you will be able to repair or replace it before things fall apart completely. When the truck’s check-engine light goes on, it is because there is a problem which is why you cannot take it for granted. It might not mean the ECM is in danger of failure but you will be able to know the kind of error code the system is sending. With this, it will be easy for the real problem to be fixed.
It is also very easy to tell when the ECM is not in good shape based on the engine behavior like misfiring or stalling. When the vehicle computer system is not working well, there could be such signs but this is a secondary problem. The symptoms might come up and subside suddenly. In addition, this is not a pattern you should be using in judging whether the symptoms are severe or not. You will also get engine performance problems if the ECM is faulty. It is the ECM that controls the timing of the fuel settings. The fuel efficiency can drop at any time and the vehicle will give you a hard time when you are trying to shift. If you notice a negative change in the vehicle’s performance, you ought to find out where the problem is emanating from.
Also, when turning on the car engine, the time it takes for it to be up and running will tell you how well the ECM is functioning. With a faulty ECM, your vehicle is not going to start and if it does, it is going to take a very long time for that to happen. If you have to replace the ECM, you should know how to get the best. Every ECM is unique to the particular vehicle which means you have to get the right number in order to tell your mechanic what has to be installed. Also, buy from a quality manufacturer for it to serve you for a long time.
