What does it mean when the engine fault light comes on at startup but then disappears?

[LaDelaney]

Engine fault light coming on at startup but then disappearing is a normal part of the vehicle's self-check process during startup. Here are explanations of several common warning lights: Battery indicator light: This light displays the working status of the vehicle's battery, usually in red or yellow. It illuminates when you turn the key for self-check and turns off automatically after engine start. Engine indicator light: This light shows the working status of the engine, primarily in yellow. It also lights up during the self-check when turning the key and turns off automatically after engine start. ABS indicator light: This light indicates the working status of the ABS system, mainly in yellow. It illuminates during the self-check when turning the key and turns off automatically after engine start.
