What happened to the epc light? Is the ignition abnormal?

The reason why epc light is on is: 1. Generally speaking, epc lights are on because of three faults. First, the throttle should be cleaned when it is dirty; On the other hand, if the brake light is not on, it is necessary to check the brake switch and wiring; In another case, the EPC fault light will also light up because of the oil problem; 2. If the epc fault light is on all the time, it means that the engine management system or electronic control has a fault, which is often accompanied by unstable idle speed of the vehicle or engine cold start jitter. But for domestic car owners, it is generally because of domestic oil quality and dirty environment in the car, which can be solved by cleaning the throttle as soon as possible. 3. When the ignition switch is turned on for function check, the indicator light epc will light up. If the indicator lights up during driving, it means that the engine power electronic control system is out of order and the engine must be checked immediately. Under normal circumstances, dirty throttle body, vacuum leakage of intake system, broken brake switch and failure to upgrade engine in time may all lead to epc failure.
