The Liwei handbrake indicator and ABS are always on

Hello, ABS light and handbrake light are generally faulty ABS system, need the computer to detect the fault code, read the data stream to find the fault location, it may be a tire ABS sensor or line fault, it is recommended to go to the repair shop to check.

Hello, it is recommended to check whether the brake fluid is lacking, if there is no problem, you need to use a professional computer to read what the specific fault code is, and carry out the next step of maintenance according to this information.

Hello, the first thing you can consider is whether the brake fluid is missing, and there is a fault of the hand brake switch.

If the handbrake light and ABS of the Liwei car are always on, check whether it is caused by sensor failure.

There are many reasons for your situation, and you need to go to a 4S shop or repair shop to test it with a computer.

If this is the case for you, it is recommended to use the computer to read the fault code and check the specific fault information.

In this case, you must go to a professional place to check what exactly causes this situation.

The main reason for the brake indicator and ABS warning light to be fully lit: this fault phenomenon is mainly caused by the drop in the brake fluid level, the decrease in the brake fluid level is mainly caused by the wear of the brake pads, and the brake fluid will drop after the brake pads are worn, and when the fluid level drops to a certain scale, the brake fluid level warning light will be lit to remind the driver to check or replace the brake pads.

In this case, it is very likely that it is a problem with the sensor, it is recommended to check it, it may be a false alarm.

Good afternoon! The general reason for this situation is that the brake fluid is missing, or the hand brake switch is damaged, and it is necessary to check the supplementary brake fluid Check the switch of the hand brake. When necessary, the ABS fault code is retrieved for troubleshooting.

There are several reasons why the ABS+ handbrake light is on:

1. The wheel speed sensor is dirty, or the error is out of tolerance;

2. The brake pads are worn to the limit;

3. Lack of brake fluid;

4. The power generation of the generator is too high or too low;

5. ABS failure.

The easiest way to determine is to test it through a special computer. If you don't have a dedicated computer, it's more troublesome. First eliminate the doubt, and then eliminate the 4th doubt, if there is a phenomenon of light at the same time, it is necessary to support the car, clean the wheel speed sensor of the 4 wheels, and then measure its value with a multimeter.

Extended information: ABS was invented to avoid the above-mentioned phenomenon of emergency brake slippage. Vehicles equipped with the ABS system use wheel sensors to monitor whether the wheels are locked.

When the wheels are locked, the ABS system will intervene under the braking system to release the pressure of the brakes, let the locked wheels brake go, let the wheels roll again, let the vehicle regain the ability to handle, and then restore the pressure of the brakes, so that the vehicle continues to slow down.

In this way, with the concept of time-sharing, the braking system of the vehicle is constantly braked-released-braked-released, so that the vehicle can maintain the ability to control between the braking intermittents, so that the vehicle can avoid obstacles and avoid accidents.

The modern ABS system can perform several to more than a dozen of the above movements within 1 second, so that the slippage of the vehicle is minimized, so as to maintain the good braking effect while maintaining the vehicle's handling and dodging ability.

In the event of an emergency braking, the driver only needs to press the pedal at the fastest speed, and ABS will intervene in the operation of the brake in a timely manner. When the ABS system is actuated, the brake pedal will be repulsed due to the repeated release of pressure in the braking system.

Check the fault** There is a fault of the control solenoid valve and the hydraulic pump, you should suspect that there is a problem with the fuse, check the power supply. The flashing light is mostly caused by the self-diagnosis excitation interface has been plugged into the fuse and entered the self-diagnosis state. Inspect the wiring of the terminal from the place to see if there is an iron connection on the wire.

Look along the line to see if the wire at the relay box is worn out and tie the iron. Check that the speed sensor of each tire is dirty or the plug must be connected; The control unit is faulty or the line needs to be connected; The system was not matched by a computer after a crash; The tire speed sensor ring gear is damaged. It is also possible that when the vehicle is driving in rainy weather, due to muddy water, dust, raindrops, etc., splashing on the chassis and other places, resulting in adhesion and barrier effect, the ABS sensor and the connected magnetic induction coil have poor conduction, resulting in a failure during the self-test, and the warning light is on.

It is recommended that you check according to the above.

There are several reasons why the ABS+ handbrake light is on:

1. The wheel speed sensor is dirty, or the error is out of tolerance;

Solution: Repair and clean the sensor.

2. The brake pads are worn to the limit;

Solution: Replace the brake pads.

3. Lack of brake fluid;

Solution: Replenish the brake fluid.

4. The power generation of the generator is too high or too low;

Solution: Control the power of the generator.

As the name suggests, a brake light is a light that lights up when a vehicle brakes. It is generally red, which plays the role of warning the vehicles behind; In addition, the brake light can effectively prevent the occurrence of vehicle rear-end collisions and reduce traffic accidents.

The brake light is brighter and more obvious, and it is mainly used to remind the vehicle behind to slow down or stop. If the brake light is used incorrectly or malfunctioning, it is easy to cause a rear-end crash.

In addition, it is important to pay attention to the replacement of brake bulbs: the tail lights of vehicles produced in China are generally"One brew for two purposes"There are two filaments in the bulb, the weaker one is the small light, and the stronger one is the brake light. Some manufacturers design it as a high and low foot plug-in type, which is very convenient to use.

Be careful not to reverse the connection when replacing.

It must be that the ABS system is faulty! Go to the 4S store as soon as possible to deal with it, otherwise it is likely to affect driving safety!

ABS light on means that there is a fault in the ABS system, the ABS system may stop working, maybe your car will be the same as without the ABS system, the braking effect of the car will deteriorate, the braking distance will increase, the handling performance of braking will deteriorate, etc., so when the ABS light is on, the fault should be eliminated in time.

The brake light is on to indicate that the braking system is abnormal, manifested in poor braking or failure, unilateral braking deviation, braking noise, brake lag caused by brake drum heating, parking brake failure, if the brake fluid is insufficient, it may affect the braking performance and driving safety, and the vehicle should be sent to the repair shop for maintenance as soon as possible.

It is recommended that you go to a professional repair shop to check it, the brake system is faulty, and the system prompts you that the ABS light will be lit.

Answer: If the engine fault light is on, then the cause may be that there is a problem with the ignition performance of the engine or the induction performance of the engine sensor exceeds the range.

If the brake reminder light is on when braking, then you need to check whether the brake fluid level is not enough or the brake pad is caused by a problem.

If it is just powered on, it means that the system is self-testing, which is normal.

If it is always on during driving, it means that the ABS is faulty and should be repaired as soon as possible.

See if the brake fluid level is low.

1.When braking, ABS can quickly judge the locking state of the wheel according to the speed signal transmitted by each wheel speed sensor, close the normally open input solenoid valve on the wheel that begins to lock, so that the braking force remains unchanged, if the wheel continues to lock, then open the normally closed output solenoid valve, the braking pressure on the wheel moves down rapidly due to the pipeline that goes straight through the brake fluid reservoir, preventing the wheel from being completely locked due to excessive braking force. In keeping the braking state at the best point (slip rate S is 20%), the braking effect is the best and the driving is the safest.

2.The brake fluid in the front cavity of the brake master cylinder is the dynamic pressure brake fluid, which pushes the reaction sleeve to the right, which in turn pushes the booster piston to move the brake pedal push rod to the right. Therefore, when the ABS is at work, the driver can feel the pedal flutter and hear some noise.

3.After the car slows down, once the ABS computer detects that the wheel locking state is gone, it will let the main control valve close, so that the system can be transferred to the normal braking state to work. If the pressure of the accumulator drops below the safe limit, the red brake fault indicator and the amber ABS fault indicator illuminate.

In this case, the driver has to use a large force to apply a deep pedal-type braking method to effectively brake the front and rear wheels.

It may be a failure of the automotive ABS system, or a failure of the master or sub pump. If the components are aging and stuttering or the sensor is faulty, the brake system should be checked and repaired before driving on the road.

One of them: the handbrake light is on, maybe the handbrake is not completely down, or there is a stuck!

Operation steps: 1. Check the brake fluid, this situation will also occur if the brake fluid is less. If less is added to the standard, it is fine.

2. Put on the jack and remove the tire.

3. Check the thickness of the brake pads.

1) This situation will also occur if the brake bridge Senzhen car piece is thin.

2) Locate the ABS sensor. The position of the front wheel ABS sensor is behind the brake disc. In the case of the left front wheel, the ABS sensor was found behind the brake disc near the rear of the car (right-hand direction).

I saw that there were a lot of iron filings on the probe head of the ABS sensor, because this place was magnetic, and attracted a lot of iron filings from the friction of the brake disc.

6. Install tires, and be sure to put the tires under the car after removing the tires to avoid the danger of jack falling. Then the ignition, ABS, handbrake lights are off, drive to the unmanned road, test drive.

Second: there are also models ABS (anti-lock braking system) lights on, you need to go to the auto repair shop with a car computer detector, detect the anti-lock braking system, read the fault code, in order to find the problem, and then repair it according to the fault information, generally the sensor is broken, only the most basic brake, ABS does not work.
