EPC in a vehicle stands for the Engine Electronic Stability System, also known as the Electronic Throttle Control. There are two possible reasons for the EPC light to illuminate: one is a dirty throttle, which should be cleaned; the other is non-functioning brake lights, requiring inspection of the brake switch and wiring. The EPC light is yellow, serving as a warning indicator. The vehicle can still be driven at this time, but it's advisable to maintain a lower speed and proceed to a service point as soon as possible for fault diagnosis. The EPC system consists of components such as sensors and controllers. When a sensor fails or detects an abnormal condition, the control system takes appropriate measures based on pre-set programs.
