Hello, the airbag coil is broken, change it [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

It is estimated that the airbag hairspring is broken, and it is recommended to check the airbag hairspring [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, I guess it's not installed with an iron wire, I hope it can help you. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello! The problem should be a hairspring damage! Or maybe the plug isn't plugged in properly!

The hairspring is man-made! It was not operated well when disassembling or installing! You can use a multimeter to teach you to measure it first!

See if there is a broken circuit! Hope it helps! [If you have a problem with the car, ask the car master.]

The steering wheel button of the car fails, the horn does not sound, and the airbag alarms.

Hello, the car steering wheel button failure is noisy, the horn does not sound, and the airbag alarm is related to the cause and treatment methods are as follows. First, first check the relevant fuse, if the fuse is faulty, it will also lead to this phenomenon and need to replace a new fuse, the second situation is caused by the damage of the airbag hairspring under the steering wheel, this series of linkage failures, this situation is the need to replace the airbag hairspring. Third, if the vehicle is still within the warranty period, it is a quality problem of the vehicle, which can go to the 4S store for free inspection and maintenance.

The steering wheel horn does not sound and the airbag light lights up Reason:

1. Instrument self-test, in the short time of entering the car and ignition, the instrument will be automatically detected, and the airbag light will automatically go out after the automatic detection is completed, which will be about 5 seconds, which is a normal phenomenon. If the airbag light is still on for a long time after the self-test, it can be judged that the real liquid sail is faulty;

2. False fault, if the battery is in trouble, it will also cause the airbag light to turn on. And the airbag will also feedback the signal of low air pressure of a certain airbag to generate a fault code, at this time, as long as the fault code is cleared;

3. If the above two reasons are ruled out, then the line may fail and should be repaired in time. The cause of this failure may be the failure of the airbag, collision sensor, airbag hairspring, etc.

1. Contact Zheng Sui ablation: If the horn is open for a long time, it is easy to produce angular contact impedance and weaken the current of the electric dissipation plexus trapped in the electromagnetic coil. The reduction in electromagnetic attraction does not attract the armature to drive the normal vibration of the diaphragm, resulting in hoarseness or even no sound;

2. Loose sealing, easy to get damp: Although the inside of the horn is closed, if the seal is not tight, when the car is washed into the fog or air, there will be water vapor, and the water vapor is easy to contact with the tide is not normal work;

3. Poor contact of solenoid terminals: Some solenoid coil terminals in the speaker are connected by aluminum rivets, and the welding connection is unreliable. If the insulating varnish at the end of the paint wire is not clean or the rivet pressure is unreliable, it is easy to misconnect the fault, resulting in poor working of the speaker.

Such a failure is a quality problem of the speaker, which cannot be repaired, and can only be replaced with new parts.

The reason is that the airbag hairspring is broken. An airbag balance spring is a wiring harness that ensures that the airbag can detonate properly in an emergency. Because the main airbag rotates with the steering wheel, there should be a margin in the connecting wiring harness to ensure that the steering wheel does not break when it is turned to one side to the extreme position.

If the airbag hairspring breaks, it will cause the light to come on and the horn to not sound.

The airbag balance spring can be thought of as a certain length of wire harness wound around the steering shaft of the square hole field disc. When the steering wheel is turned, it can be loosened in the opposite direction, or it can be wound tighter when it is appropriate, but there are limits. When the steering wheel strikes left or right, it is essential to ensure that the wiring harness does not break.

At present, the airbag system is generally a single airbag system or a double airbag system for the steering wheel. In the event of a collision in a vehicle equipped with dual airbags and seatbelt pretensioner systems, the airbags and seatbelt pretensioners will act at the same time, regardless of the vehicle speed, resulting in the waste of airbags in low-speed collisions and greatly increasing maintenance costs.

The dual-action dual-airbag system can automatically choose whether to use only the seatbelt pretensioner or the seatbelt pretensioner and the dual-airbag at the same time according to the speed and acceleration of the car in the event of a collision. In this way, in the event of a collision at low speeds, the system only needs to use the seat belt to protect the safety of the driver and passengers, without wasting airbags. In the event of a collision at speeds of more than 30 km/h, seat belts and airbags will work at the same time to protect the driver and passengers.

Check that the main reasons for the speaker not ringing or the sound is withering are the battery preservation, the horn relay and button damage, the horn damage and other power supply systems. Turn on the headlight switch, and if the headlight is not lit or dimmed, start the engine and open the throttle slightly. If the headlamp is normal and the speaker is making a sound, the battery dismantling power is insufficient, check the battery and its connecting cable.

1. Contact ablation: the horn is open for a long time, and it is easy to produce angular contact resistance, which is easy to weaken the current through the electromagnetic coil. The reduced electromagnetic attraction does not attract the armature drive diaphragm to vibrate normally, and the sound is hoarse and silent.

2. Loose sealing, easy to damp: the inside of the horn is closed, but the sealing is not tight, and there is water vapor when the car enters the fog and air. 3. Poor contact of solenoid coil terminals

The connection of the solenoid coil terminals in the speaker has aluminum rivets, and the welding connection is unreliable. The insulating varnish at the end of the enameled wire is dirty or the rivet pressure is unreliable, which can easily cause misconnection failures and lead to poor speaker operation. This failure is a loudspeaker quality problem that cannot be repaired, and can only be replaced with a new zero brigade round excavation.

The abnormal noise produced by the steering machine may be due to the contamination of the auxiliary oil. If the auxiliary oil is dirty, the pressure of the power system will increase, the auxiliary pump may make a humming sound, the steering column is not lubricated sufficiently, the friction is high, and abnormal noise is produced. Please add directional oil as soon as possible.

The damage of the steering column under the steering wheel, the hairpin of the steering knuckle of the steering column under the steering wheel, the lack of oil in the steering bearing, and the dust jacket of the side cage affect the sediment entering the cage, and the steel ball in the cage is poorly lubricated, which almost all affect the abnormal noise during steering. It is best to better judge the specific reasons for the actual vehicle inspection, and advocate the implementation of the exclusions in order from simple to complex. How to eliminate the abnormal noise of the machine in the direction of the car:

1. The friction direction between plastic parts The machine is composed of various plastic parts, and the gap is too small when rotating, and there will always be different sounds. Especially for new cars, it's good to brush it for a while. After grinding, if there is a different sound, the steering machine can be reinstalled; 2. Friends who have released the steering wheel due to the failure of the airbag in the steering machine should be more careful.

The balloon cable may be disconnected, or the plug of the balloon cable may not be inserted. Replace the airbag cable or fixed plug; 3. When the direction of the steering wheel failure is "thundering" for the first time, the gap between the steering wheel and the gear is too large, and the steering machine may not be replaced.
