ECM stands for Engine Control Module which is considered as the vehicle’s brain. It regulates the intersection of the engine’s pivotal pieces of stuff to produce the required amount of energy and spark. The presence of grounding issues can cause failure in the Engine Control Module. To keep ECM performable, make sure you don’t have a bad injector wiring harness. Also, you need to be aware of the fault codes so that you can identify the problems and fix the issue before the damage becomes irreversible.
