What is the reason why the EPS fault light is on after the car wash?

The EPS light is on means that the electric power steering system is faulty, and the symptoms are: heavy steering, abnormal steering noise, steering wheel shaking, poor steering wheel return ability, etc., it is recommended to go to the auto repair shop for maintenance in time. At this time, the car should be stopped as soon as possible under the premise of ensuring safety, ** seek help from a 4S shop or a professional auto repair shop, and it is best to let the trailer tow away.

It's just that the steering wheel is out of power and becomes very difficult to control. If the vehicle does not show any of the above symptoms, you can stop the vehicle and restart the engine to see if that solves the problem. If you restart the engine, you can continue driving, but you should also go to a 4S shop or a professional auto repair shop as soon as possible for inspection.

Try to avoid aggressive driving while driving.

The full English name of EPS is Electronic Power Steering, that is, electronic power steering. It uses the power generated by the electric motor to assist the motorist in power steering. The composition of EPS is generally the same for different cars, although the structural components are different.

Generally, it is composed of torque (steering) sensor, electronic control unit, electric motor, reducer, mechanical steering gear, and animal battery power supply.

When the car is driving, it is subjected to lateral and longitudinal forces, and when the lateral force is too large, the handling force is reduced a lot, and it is easy to lose control. ESP improves this, when the vehicle is unstable, based on the CPU calculation, the electronic power assist system can independently brake each wheel and participate in the management of the engine system to ensure the safety of driving.

It's okay, it splashed with water, it's not a big problem.

Hello, this situation is also faulty. You need to go to the repair shop and check it with a computer to know the specific reason.

This is because the driver touches an OFF button, EPS is the anti-slip system, every time it starts, it will be turned on by default, if the driver touches the OFF button to turn off this function, the instrument will display the EPS light, the specific operation steps are as follows:

1. Open the door on this side of the cab.

2. Press the brake pedal.

3. Press the one-key start button to start the engine.

Fourth, the instrument panel lights up, proving that the engine has been started.

Fifth, press the button in the figure to turn off the anti-slip function.

Notes:1. Anti-skidding can increase vehicle stability.

2. Do not turn off the anti-slip function on rainy and snowy roads.

If the ESP fault light turns on and reboots and goes off, it is generally caused by the following reasons:

1. If the ESP fault light flashes when it is on, it means that the system is in working mode at that time, which is a normal phenomenon.

2. If the fault light is always on, and there are no other fault lights on, it is generally caused by the loss of signal of the components of the body stability system, and the common one is the failure of the angle sensor, lateral acceleration sensor or wheel speed sensor.

3. If it is lit together with the engine warning light or other system warning lights, it may be that the signal of a key electrical component is lost, resulting in the failure of the vehicle system to work normally. 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.

Precautions for EPS lamps.

Frequently check whether the mains voltage is normal, whether the zero and live wires are misaligned, especially if the front end of the EPS is a power grid with dual mains or with a standby generator set, it is necessary to check whether the zero and live wires of the first main power supply and the second backup power supply are consistent, and if the misalignment is found, it must be corrected immediately, otherwise it is easy to cause EPS failure.

Users who are equipped with lightning protection at the front end of the EPS should regularly check whether the lightning protection and grounding wire are normal. Sites with a large number of rodents should generally install protective sleeves outside the input and output cables.

See if the air filter should be cleaned, the air filter filter is too dusty, when not stepping on the accelerator, the engine needs not enough air, resulting in instantaneous flameout, EPS detected the instantaneous flameout error signal, and executed the wrong command to turn off the power assist function, and the car is only instantaneously turned off, and the other sensor detected that there is no electronic assistance, so the EPS light is on, I often have this problem two days ago, after cleaning these days did not appear for the time being, my car is Dongfeng Xiaokang C37. The above is just my reasoning, it has yet to be verified!

Hello, this is a computer self-test, occasional problems, as long as it is not always on, it is fine, it is recommended to look at the brake light first, if it will be on later, go to the repair shop computer to check it, I hope it can help you, I wish you a happy life!

Check the power assist motor plug and battery, generator.

Hello, it is recommended to go to the repair shop for computer testing, specific analysis of specific problems, I hope my answer can help you, I wish you a happy car!! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

In this case, you can go to the repair shop or 4S shop. Check it, interpret the fault code, and repair it according to the prompts.

Normal, if the light still turns on after starting, it is faulty.

Hello, generally this is normal, if you are not at ease, it is recommended to go to the store to check, thank you.

Hello, as long as the EPS light is not turned on, it is normal. Because when the key is opened, all systems must be inspected for quality, if it is still bright after starting, it is not normal, and it is necessary to go to the maintenance plant to check and troubleshoot. I hope it can help you, I wish you a happy car [car questions, ask the car master.

After the car is powered on, the indicator light goes out, and there will be a self-test process, EPS

If the lights are still on, all the indicators will turn on after about 15 seconds. If it is started, it is necessary to check whether the electric power steering system is faulty, and the self-test is completed.

After the car is powered on, there will be a self-test process, all the indicators are on, and after about 15 seconds, the self-test is completed and the indicators are off. If you start after eps

If the lights are still on, check whether the electric power steering system is faulty.

When the EPS light is on, it is good to smile and regret and re-ignite. It could be because there is a problem with the sensor. In this case, you can check for faults in your car**.

EPS refers to the steering assistance system of the car. When driving, if the car's dashboard lights up the EPS light, it means that the car's steering assist system is out of order and needs to be repaired in time.

There are three types of power steering systems, namely HPS hydraulic power steering, EHPS electro-hydraulic power steering, and EPS electronic speed drive power steering.

Causes of EPS failures and how to remove them:

In the event of a power outage, loss of power or battery replacement in the vehicle, the cause of the EPS failure is the loss of data from the steering module.

In this case, you only need to start the car in the same place, touch the steering wheel left and right a few times, and then drive the vehicle for about 30 to 50 kilometers, and the EPS fault light will be automatically eliminated. If the fault lamp cannot be eliminated by the above method, then use a diagnostic device to rematch the data.

Damage to the torque sensor, damage to the coil inside the sensor, and also cause the EPS fault light to illuminate. Replacing the torque sensor directly can solve the problem, but it should be noted that if the torque sensor is integrated into the steering machine, then the steering machine assembly needs to be replaced.
