How to Clear a Car's Malfunction Indicator Light?

[StElaina]

When a car's malfunction indicator light comes on, it usually needs to be diagnosed and cleared using a fault code reader at a 4S shop. There are two scenarios when the engine malfunction light illuminates: 1. Yellow symbol light: This indicates a minor engine issue that doesn't affect normal operation, but still requires inspection and repair. 2. Red symbol light: This signals a serious engine problem that normally requires immediate service. In emergency situations, you may drive cautiously while closely monitoring the engine's condition. However, if the coolant temperature warning light or oil pressure warning light comes on, or if you notice obvious vehicle malfunctions, you should pull over immediately and call a repair shop for assistance to prevent damage to the engine's performance.
