What if the car always appears EPC?

The automobile instrument shows "EPC", indicating that there is something wrong with the engine power control management system. Generally speaking, EPC lights have two possibilities. First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring. Also, due to the oil problem, the EPC fault light will also light up.

After the key door is opened, the vehicle starts self-inspection, and the EPC indicator light will light up for a few seconds and then go out. If the vehicle does not go out after starting, it means that the mechanical and electronic system of the vehicle has failed.

Description of other automobile fault lights

1, thermometer: water temperature alarm

The water temperature indicator lamp is used to display the temperature of coolant in the vehicle engine.

Some models without water thermometer will display the coolant temperature in the color of indicator light:

1, blue indicates that the water temperature is too low;

2. Extinction indicates that the water temperature is normal;

3. Red indicates that the water temperature is too high.

What the engine fears most is the lack of oil and water. The lighting of water temperature alarm lamp is equivalent to the risk factor of oil alarm. If the temperature is too high, the engine will overheat and the cylinder will be deformed. The owner can add coolant or pure water for emergency. If "cylinder stuck" and "cylinder gasket" appear, please contact the trailer for rescue immediately.

2. Aladdin magic lamp: oil alarm lamp

This indicator lamp, which looks like Aladdin's magic lamp, is the oil alarm lamp! When the light is on, it means that the oil storage and pressure are lower than the standard value. If you continue driving, the engine will lose lubrication and cause serious wear and tear.

If the fault light does not disappear after refueling, please do not start the vehicle and contact the rescue as soon as possible.
