Car ignition does not respond, warning headlight system error.

EPC= Electronic Power Control belongs to the engine management system. During the ignition, the engine control unit detects the electronic throttle system to detect the occurrence of a fault, and displays it through the yellow EPC light installed in the instrument cluster. When the engine starts, the indicator light will light up for a few seconds. If there is no fault memory in the fault memory, or no fault is detected at this time, the indicator light will go out automatically. If there is a fault in the system, the engine control unit will light the EPC light and the fault will be remembered. The EPC light is not a serious problem. Even if the EPC is completely damaged, only the engine speed will not be adjusted. Generally, when this fault light is on, the car will occasionally fail to refuel and the engine will shake. First, check whether the brake light switch and rear brake light bulb of your car are broken. If there is no problem, the engine throttle is out of order and needs to be cleaned or replaced.
