What happened to the car epc light?

The lighting of EPC lamp may be affected by three fault problems, such as: first, the throttle valve is dirty and needs to be removed immediately; Second, the brake light is not necessarily on, so it is necessary to check whether the brake switch and circuit are normal; Finally, there may be oil problems. In addition, the EPC fault indicator will also light up.

The EPC light is always on, indicating that there is something wrong with the engine management system or electronic control. This situation is often accompanied by the unstable idle speed of the vehicle and the trembling and vibration of the engine during cold start. In this case, you should immediately drive to the service shop for inspection and maintenance.

In addition to the above situation, there may be false positives and unexpected failures of ECU. You can rewrite the ECU data to see if the EPC light is still on or the owner can restart it by trying to turn it off. If it doesn't light up, it means that only the EPC light is affected and it is falsely reported. If the EPC light is still on or always on, you need to take the previous measures.

Extended data

Whether EPC light can continue to run normally depends on whether the light is red or yellow.

1. If the yellow light is on, you can continue driving.

Lights of different colors come on, indicating different meanings. When the yellow car fault light is on, it means a warning, indicating that the car fault problem is not very urgent. Therefore, if the yellow light is on, you should pay attention to checking the car immediately and detect any problems.

If the red light is on, you need to stop and check.

When the red light is on, it means that the failure of the vehicle will affect the core components of the vehicle at the same time, even the driving safety of the vehicle. At this time, stop immediately to detect the fault, and then start driving after the fault problem is solved.
