The Roewe E550 fault light is fully lit and the dashboard appears EP, and the car loses power

The computer detected that the road valve was abnormal. Do a whole car inspection.

Check the maintenance manual of the corresponding model to understand it, and you should find a professional maintenance personnel to find the fault code through the diagnostic instrument to locate the fault part.

It is recommended that the 4S shop go to the inspection or the big repair shop to check the specific fault.

If you have a specialization in the art industry, it is better to leave it to the expert to solve this fault phenomenon.

If the instrument indicator light is not on, first check the vertical fuse of the power supply of the dashboard.

If the circuit breaker. will need to be replaced. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there will be an open circuit or a short circuit, which will also lead to the car dashboard.

There is no light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00000000 front fiber staring km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the silver and readings on the odometer to the 0 position.

The reasons for the power failure of the whole car are: 1. The battery itself has been consumed and out of power; 2. The battery binding post falls off; 3. The line from the battery to the fuse box is damaged or burned; 4. The main line of the insurance, the total fuse of the nuclear Biliang, and the total electrical appliances are burned and widened or damaged; 5. The total number of key opening losses is broken.

Under normal circumstances, when we insert the key in the vehicle and open the key door, the instrument lights will have a process of all lighting, and some of the lights will go out by themselves after a while, and the engine lights will go out after starting, we call this situation the instrument indicator self-test. Under normal circumstances, the vehicle instrument lights need to be self-tested. If you don't check yourself, you have a bad attitude.

Today, we take the engine fault light as an example to illustrate that the possible failure reasons for the self-test light not to light are:

After the car opens the key, the engine indicator light does not light up and cannot be started, mainly because the rock book or rough circuit is not working, specifically:

1. The two contacts between the battery and the starter are loose;

2. The two contacts between the starter and the key door are loose;

3. The two contacts between the key door and the switch are loose;

4. The computer board socket is bent, deformed and loose, and the jack is oxidized and rusty. Disassemble the socket of the computer board to check the jack, and use a steel needle to remove the rust. ECU socket deformation correction: use a hair dryer.

After properly heating the socket, quickly insert the ECU, tie it tightly with tape, and release it after cooling to restore the normal shape of the socket.

5. Check the total fuse box and ECU fuse.

main relays, etc.

I hope mine can help you, hopefully.

This situation of Roewe 550 is due to the failure of the anti-theft verification or abnormal network communication. In this case, make sure the battery is sufficient, and then check the anti-theft system. If no problem is found, this situation is caused by the damage of the body computer, the abnormal network communication and the problem of the engine computer itself.

The car uses a multi-channel transmission system, the voltage of the two network cables is volts and volts respectively, the resistance between the two network cables is 60 ohms, can be prepared to measure the position of 11 and 3, 14 and 6 in the diagnostic socket, there is an abnormal resistance or voltage, consider the problem of the line itself or the body computer is damaged, otherwise the roller pin needs to replace the engine computer, the new computer needs to be programmed, otherwise it can not be used normally, and the maintenance computer replaces the internal communication module at 300 yuan. Find a local automotive electronics master to repair, and you will not be charged for repairing it.

Summary. What causes the engine failure light to turn on? Reason 1:

The engine burns badly. Sensors are installed on the engine's exhaust gas emission device to detect exhaust emissions. If the combustion state of the engine is not good, it will cause a change in exhaust emissions, causing a system alarm.

The quality of the oil is poor, and different types of oil are mixed. Reason 3: There is carbon deposition in the engine cylinder.

When the engine is used for a period of time, the carbon deposits generated will store heat, resulting in disorderly ignition of the engine, causing the engine to detonate and causing the system to alarm. Reason 4: The fuel tank cap is pressed against the pipeline.

Dear, this cavity is so accompanied by the round obstacle lamp, Lu Chong with a picture with analysis.

Hello teacher, my fault light is on, showing that there is a problem with the hybrid, if the fault light is not lit just now, the brake can not be stepped on, if the slag hunger force will go down, the fault light will be rotten, and the throttle will not respond, dear, stop the car on the side of the road If you continue to drive the vehicle, it may cause breakdown, power drop and other adverse consequences.

What causes the engine failure light to turn on? Reason 1: The combustion state of the engine is not good.

Sensors are installed on the engine's exhaust gas emission device to detect exhaust emissions. If the combustion state of the engine is not good, it will cause a change in exhaust emissions, causing a system alarm. Reason 2:

Reason 3: There is carbon deposition in the engine cylinder. When the engine is used for a period of time, the carbon deposits generated will store heat, resulting in disorderly ignition of the engine, causing the engine to burst and cause the system to alarm.

In case of failure, it can only go 23 to 25 horses.

But reversing is still possible.

Dear, there are several reasons for this: 1. The main reason why the engine failure light is on in the combustion state of the engine. 2. The engine exploded into a world earthquake.

3. The internal reasons for the engine failure light to be on: fuel quality, clean inside the engine cylinder, and carbon deposits. It is advisable to go to the 4S shop as soon as possible to read the fault code to judge the problem.
