Hongqi Century Star stepped on the clutch ABC light on 5

Fault: ABS warning light alarm.

Inspection: The car is equipped with an Audi engine, ABS system using Bosch products, the model is Bosch ABS ASR, the version is D00, the code is 00000. use, but not into the ABS control unit.

Analysis: There are three reasons why the control unit cannot enter: the control unit does not get the power supply, including the No. 30 normal fire wire, the No. 15 key live wire and the grounding wire; damage to the control unit; Faulty diagnostic instrument or diagnostic line failure.

Exclusion: Start by measuring the positive power and ground wires of the ABS control unit. Read the circuit diagram, see that the 17 pins and 18 pins of the ABS control unit are 30 normal fire wires, measure the two pins of the wiring harness plug of the control unit have no voltage, and then measure the voltage at the ABS fuse wire, so as to judge that there is a break point between the fuse wire and the plug of the ABS control unit.

Troubleshooting: Strip the wiring harness, find the break point, connect and wrap the insulation, the ABS control unit can enter, clear the fault code, the above troubleshooting.

ABS motor may have a problem and need to replace the ABS pump assembly to solve the problem, this thing is not good and still has a great impact on the safety of braking, especially at the moment of emergency braking, ABS failure will lead to safety accidents such as loss of control of the vehicle's side flick direction.

The line in the control unit of ABS is virtually connected. I use it so without delay. No compromise on safety. The condition of the sensor line can only indicate that that section is normal. Other parts of the control unit are a different thing [such as hydraulic motor pumps].

。。。It's better to be cautious about braking.。。。 Saying goes; I'm not afraid that if I can't run fast, I'm afraid that I can't stand...

Fix the problem and open it again... Safety first!!!

According to what you said, it should be possible that the sensor of the wheel is dirty, and the signal of a certain wheel is interfered with, prompting an alarm. ABS fault can be directly retrieved by the computer, and at the same time check whether the brake fluid is lost, or should be replaced. It is recommended that you go to the 4S store as soon as possible for cleaning and inspection.

Hello car owners! According to your description, both possibilities are possible. The roof of the car needs to be further observed and inspected. It's about two or three hundred dollars.

Hello, generally the pump is more broken, you can see it [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

If you see a pump leaking, the pump is broken, and if you see a pipe leaking, the pipe is broken. 4S shop professional technician, 10 minutes to solve. 】

When the engine is running, there are a number of systems that perform a self-test. Whether there is a fault in each system is displayed by the indicator light on the instrument, and the fault light will be lit and the fault light will be extinguished. These indicators are controlled by the control computer, so the whole process is that each system sends the self-test results of Warimno to the control computer, and the kernel shouts that the instrument light is extinguished and lit by the computer.

It should be judged that it is possible that the sensor of the wheel is dirty, and the signal of a certain wheel is interfered with, prompting an alarm. ABS combustion defects can be directly retrieved by holding the section letter computer, and at the same time check whether the brake fluid has a loss of section wheels, or should be replaced. It is recommended that you go to the 4S store as soon as possible for cleaning and inspection.

If you want to reactivate the car that has been parked for a long time, you must do an inspection when you want to re-activate, otherwise there will be such and such problems, and the engine will be damaged in serious cases. Check the hydraulic oil of the clutch without the clutch, it may be that the hydraulic oil is insufficient.

When the car is driving on the road and stepping on the clutch, Du is just to change gears and stop the car. You don't need to tell the DAO to change gears

Know others, but stop after changing neutral gears, for sure.

If you step on the brakes, you must inform the vehicle behind you that the vehicle in front should slow down and pay attention to safety, so the car is equipped with brake lights. Therefore, there is no need to inform others when the vehicle steps on the clutch while driving, but the vehicle behind the brake will know.
