What does an EPC displayed on Jetta dashboard mean?

EPC is electronic power control. (full name of engine electronic stability system), many people also call it electronic stability control.

The system consists of some sensors, controllers and other components. When the sensor fails or an abnormal situation is sensed, control

The system will take corresponding measures according to the set procedures. EPC indicator lights are more common in the public.

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, for example

There is something wrong with the mechanical and electronic system of the vehicle. Generally speaking, EPC lights have two possibilities.

First, the throttle is dirty and needs cleaning. In another case, the brake light does not light up, so it is necessary to check the brake switch and wiring, and the EPC fault light will also light up because of the oil problem.

Extended data:

When turning, a feasible control strategy is that when the vehicle tends to understeer, the system can apply braking force to the rear wheels inside the turn. As the longitudinal force of this wheel increases, the lateral force it can provide decreases, and then a torque is generated to help the car turn.

When there is a tendency to oversteer, the system can apply braking force to the front wheels outside the turn. As the longitudinal force of this wheel increases, the lateral force it can provide decreases, and then a torque against steering is generated on the car body. So as to ensure the driving stability. Some electronic stability program systems will also reduce the engine power when the vehicle is out of control.
