DESCRIPTION
The Electronic Control Module (ECM), also known as the Engine Control Module, is a computer that controls various engine functions in a truck. It receives data from sensors throughout the vehicle, analyzes it, and then sends commands to different components to ensure proper operation. The ECM is responsible for regulating fuel injection timing and quantity, ignition timing, idle speed control, and emission control systems. It also monitors the performance of these systems and alerts the driver if any issues arise. The part number 3681541 refers to a specific ECM model used in certain truck makes and models.
