What is the problem when the EPC light of the Ruifeng 2 8T diesel car is on?

EPC Electronic Power Control (full name of Electronic Engine Stability System), many people also call it electronic throttle. The system consists of a number of sensors, controllers, and other elements. When a sensor malfunctions or perceives an abnormality, the control system takes appropriate action according to the programme.

For example, when we are accelerating, the control unit senses that the throttle is open. At this time, due to the failure of the brake light switch itself, the control unit receives the braking signal given by a brake light switch, and the control unit should reduce the fuel injection time and reduce the power output of the engine according to the program.

However, at this time, the control unit also receives the throttle acceleration request signal, which the computer thinks contradicts each other. When the control unit cannot accurately determine the cause of the fault, it will first light up the EPC lamp and alarm the user to check. In this sense, the EPC lights are somewhat similar to the fault warning lights or the engine "check" lights that are more common in American cars.

EPC indicators are more common in Volkswagen cars. When the key door is opened, the vehicle starts self-checking, and the EPC indicator lights up for a few seconds before turning off. If the vehicle does not turn off after starting, it means that the vehicle's mechanical and electronic systems are malfunctioning.

Generally speaking, there are two possibilities for the EPC light to be on. First, the throttle is dirty and should be cleaned. Another situation is that the brake light is not on, and you need to check the brake switch as well as the wiring.

Also, due to oil problems, the EPC faulty lamp will also be lit. The EPC light of the general Volkswagen's car indicates that there is a problem with the vehicle, and it is recommended to go to the 4S store for inspection as soon as possible.

The indicator light is lit to indicate: 1. There may be a fault in the electronic throttle system; 2. The brake switch is damaged; Solution: Clean the carbon deposits in the throttle part; After cleaning, it is necessary to use a special computer to re-learn and match the throttle position; The normal opening cannot be greater than.

What is the problem with Refine EPC lights on? What is the problem with Refine EPC lights on? Ruifeng EPC light is on, which may cause the following two problems:

1.The valves are dirty and should be cleaned. 2.

If the brake light is not on, replace the bulb or check the brake Nahu switch as well as the wiring. The following is the relevant information: the fault light is always on on means that the engine management attitude dispersion system or electronic control is faulty, often accompanied by the vehicle idle unstable or engine cold start shaking ZD movement.

For domestic car owners, the hole is due to the quality of the domestic oil and the dirty environment of the car environment, as soon as possible to the maintenance service station for maintenance, cleaning the throttle can be solved. 2.The indicator light EPC will illuminate when the ignition is turned on for functional checks.

If this indicator lights up while driving, it means that the engine power electronic control system is faulty. The engine must be checked immediately. @2019

The EPC lights of 10 JAC Refine cars are due to a problem with the car's body stability system.

The solution is: go to the 4S shop or repair shop of the car in time to overhaul the body stability system of the car to solve the situation that the EPC light of the car is on.

The body stability system and the ABS system of the car are interrelated, and the failure of one of them will usually affect the operation of the other system. Therefore, when the body stability system fault light is lit, it is very likely that the ABS fault light will be lit at the same time. This has a great impact on the stability of the vehicle during emergency braking.

The cruise control is broken, turn on the key, don't start the engine, press the cruise control, the EPC fault light disappears, turn off the cruise control, and try the ignition.

This is not easy to say, it may be that the throttle is dirty, find a repair shop to clean it, but it is not recommended to use a special throttle cleaning agent, just use a carburetor cleaner, the special one is about 200, the carburetor cleaning agent 30 is enough, the effect is the same, clean the carbon deposits of the throttle tuyere, in one is the brake light, check whether the bulb is broken, the rest is not very clear, it is recommended to go to the repair shop or 4S to check.

See if the brake light is on, and then clean the lower jointer door and eliminate the fault code, no problem.

As long as the ESP fault light is always on, because it involves driving safety, the vehicle must be driven to the maintenance organization as soon as possible, and the storage of the fault must be retrieved through professional diagnostic instruments, so as to further determine the cause of the fault and eliminate it.

The EPC light is on to indicate that the engine electronic control system is faulty, focusing on checking the wiring, electronic throttle, and engine computer. It is recommended to go to the repair station for maintenance. Generally speaking, there are two possibilities for the EPC light to be on.

First, the throttle is dirty and should be cleaned. Another situation is that the brake light is not lit and seeps out, and the brake switch and wiring need to be checked. In addition, if the engine is turned off due to improper operation, this indicator light will also light up, and the light will go out after the ignition is shouted again, which means that everything is normal.

The reasons for the EPC light to light are roughly as follows: the EPC light is mainly caused by the dirty throttle body, which only needs to be cleaned and then rematched; There is also a leak in the air intake system, which causes the engine control unit to light up the EPC warning light after detecting the problem; Leakage in the crankcase ventilation system can also lead to this failure; Serious or obvious vacuum leakage is not a problem, only a slight leakage, the control unit can not be effectively detected, the compensation adjustment carried out by the control unit exceeds the limit allowed by the internal program of the control unit, the control unit will judge that there is a problem with the electronic throttle system, and the EPC fault lamp is lit; However, the actual cause of the EPC light in this process is not caused by the functional problem of the electronic throttle control system itself, but also by the failure of the brake light switch.
