Yes, the engine control module (ECM) typically needs to be grounded to ensure proper operation. A good ground connection helps prevent electrical noise and ensures reliable signal transmission between the ECM and other components of the vehicle's electrical system. Poor grounding can lead to erratic behavior, faults, or failure of the ECM. Always follow the manufacturer's specifications for grounding practices.
