The ECM, also known as the engine control unit (ECU), plays a crucial role in controlling various functions of the vehicle, such as fuel injection, ignition timing, and emissions control. The power supply circuit is responsible for providing the necessary voltage to the ECM for it to function properly. When this circuit malfunctions, it can have significant implications for the vehicle's performance and overall operation.
