What does it mean that the dashboard of Shanghai Volkswagen shows EPC?
EPC lights are similar to fault warning lights. When a sensor fails or senses an abnormal situation, the ECU will light the EPC light to inform the driver that the engine electronic control system has a problem and needs maintenance.
Epc indicator light is very common among the public. Usually, when the key door is opened, the vehicle will perform a self-test, at which time the epc will light up, but then it will go out. If the vehicle has not gone out after starting, it means that the mechanical and electronic systems of the vehicle have failed and need to be dealt with in time, otherwise it will affect your normal driving.
Extended data:
The reason why epc indicator light is on is:
In 95% cases, the throttle valve is dirty and needs to be cleaned, but some of it is because the brake light is not on, so it is necessary to check the brake switch and wiring. In rare cases, it will light up because of gasoline quality problems, which is the cause of personal refueling mistakes (except for oil quality problems in individual areas).
Troubleshooting methods:
Air intake system troubleshooting, fuel selection reaching the standard, throttle body cleaning, etc. Remove carbon deposits in related parts. Brush ECU related data (in the case of other faults), if it still can't be solved, you can only go to 4S shop for repair.
