What Does Engine Control Module Failure Mean?
1 Answers
Engine control module failure may be caused by an ignition system malfunction. Below are the possible causes of engine control module failure: Starting system malfunction: Starting system issues prevent the engine from cranking or cause it to crank too slowly: insufficient battery charge, loose or severely corroded battery terminal connections; blown main circuit fuse; starter motor failure; open circuit in starting wiring or poor connector contact. Ignition system malfunction: For ignition system failures, turn the ignition switch to the start position to determine the nature and location of the fault. When a vehicle's engine operates abnormally but the self-diagnostic system doesn't output any trouble codes, it becomes particularly necessary to rely on the operator's inspection and judgment.
