EPC is the full name of engine electronic power automatic control system, and it is also called electronic throttle by many people. EPC display lights are very common among the public. After opening the car key door, the car gradually self-checks, and the EPC display light lights up for a few seconds, and then goes out. If the car still doesn't go out after starting, it means that the mechanical equipment and electronic control system of the car are abnormal. Under normal circumstances, there are two possibilities for EPC light to turn on. First, the throttle of the car is dirty and needs to be cleaned. In another case, the brake lights don't work. Check brake control switch and route. First, we insert the car keys into the car, turn to the NO position, step on the accelerator pedal and let the engine work. Then, we spray the car accelerator with detergent, wipe the place where the detergent has been sprayed, and wipe off the stains and carbon deposits on the car accelerator.
