How to Reset the Engine Malfunction Light?

[VonJames]

Methods to reset the engine malfunction light: You can start and turn off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. This usually resets the light. If the light remains on after disconnecting the power, or if it turns off initially but comes back on after a few days, this indicates an actual engine malfunction, and you should take the vehicle to a repair shop for diagnostics. The engine malfunction signal is issued by the ECU (Engine Control Unit), which controls all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel pump, and covers systems such as intake, exhaust, fuel, ignition, and timing.
