Car airbag burst, how to replace?
Vehicles in the normal use cycle of the airbag is almost no fault, you need to go to the store to check the airbag and its accessories. It should be replaced immediately. The airbag indicator light still does not flash or go off after the vehicle starts, which means that the airbag is malfunctioning. When the vehicle is running, the airbag indicator light flashes very long, indicating that the airbag is faulty.
The airbag is an assembly part and can only be replaced completely. Therefore, once the airbag explodes, it is necessary to replace the following set of accessories: mechanical airbag: sensor, airbag assembly, gas generator and other components. Electronic airbag: sensor, airbag assembly, gas generator, electronic control unit (ECU) and other components.
- Put the steering wheel -1- in the middle position (the wheels are in a flat and straight position) - pull the interlock plug off the airbag unit. Installation instructions: The ark plate and air bag made by the same manufacturer are installed together. -- Turn on the ignition device -- connect the battery connection board. Note: no one is in the car at this time.
For the replacement problem, you can go to the auto 4s shop detector for fault detection. And then replace it. The airbags are installed on the front (front and rear of the driver's seat), the side (front and rear of the car) and the roof of the car. The air bag consists of three parts: the air bag, the sensor and the inflation system.
As long as the airbag can be replaced, the airbag is a disposable product each airbag can only be used once, and must be returned to the factory for a new airbag after detonation.
The resistance of the main air bag is too high
Excessive resistance of the main airbag can be caused by a variety of reasons, including but not limited to:
Poor wiring harness connection: The airbag wiring is not well connected, causing the system to prompt high resistance. In this case, you need to use the computer to detect, determine which air bag resistance value is too high, and then check whether its corresponding wiring harness plug is loose, if it is loose, it should be re-plugged.
Air bag plug loose: Check whether the air bag plug is good and barrier-free, if the air bag plug loose, just reinsert it.
Air bag spring abnormal: air bag spring is connected to the main air bag of a variable length of the line, if the air bag spring abnormal, it will lead to the air bag light, high resistance, need to be replaced in time.
Abnormal airbag module: The abnormal airbag module in the main driving position will also cause the airbag light to light up and report the problem of excessive resistance, which cannot be repaired and can only be replaced.
External power interference: Interference from an external power source to the airbag controller may also cause excessive resistance. In this case, it is recommended to go to a professional garage for testing and maintenance.
When dealing with the problem of excessive resistance of the main air bag, we should first check whether the above situation exists, and take corresponding maintenance measures according to the specific circumstances. At the same time, the owner should be careful not to place items above the airbag, so as not to affect the normal work of the airbag. When the airbag has any abnormal, it should be repaired in time.
Why do some crash airbags fail to deploy?
1, this speed is not the same as the manufacturer's adjustment provisions will be different, the general speed is higher than 30km/h, the gas is likely to pop out.
2, if the car has a collision, the airbag does not pop up, may be caused by the following reasons: First of all, the airbag itself is faulty, this situation exists, and there is a certain universality, such as many owners in the maintenance of the vehicle, ignoring the inspection of the airbag, it is difficult to cause the vehicle to play a role at a critical moment.
3, the first thing to say is the trigger point, no matter how severe the collision, no touching the trigger point of the air bag, the air bag can not pop out in any case.
4, if the passenger is not fastened seatbelt, then the pop of the air bag causes the huge impact force to fall on the vulnerable part of the passenger, which will cause very great injury and even lose life. Therefore, whether the airbag is safe must be combined with the safety belt to determine.
The car crashed and the airbag didn't pop. Is that normal? What is the reason?
The point explosion of the car airbag must be opened to the collision sensor, and the car airbag will pop up when the face is in a more serious collision, but if the car's collision Angle is wrong, such as the headlight position and the front tire position, the car airbag will not necessarily pop up.
The reasons for the failure of the airbag in a vehicle collision are as follows: not all collisions will trigger the airbag. The airbag is controlled by the collision sensor. If the sensor conditions of the airbag are not met, the airbag will not pop out.
Generally, a serious collision in the front will pop up normally, but if the collision Angle of the vehicle is wrong, such as the headlight part, the front wheel part, or the back of the car is hit, the airbag will not necessarily pop up. Speed, collision object: In addition to the collision Angle, the ejection of the airbag is also related to the driving speed and the collision object.
What causes the vehicle to crash and the airbag to not deploy?
The point explosion of the car airbag must be opened to the collision sensor, and the car airbag will pop up when the face is in a more serious collision, but if the car's collision Angle is wrong, such as the headlight position and the front tire position, the car airbag will not necessarily pop up.
Collision Angle trigger sensor: the airbag is not plain and simple will pop out, it is equipped with sensors, if the car does not touch the sensor of the airbag when the collision, the airbag will not pop out.
If the car crashes, the airbag does not pop out, it may be caused by the following reasons: First, the airbag itself is faulty, this situation exists, and there is a certain universality, such as many owners in the maintenance of the vehicle, ignoring the inspection of the airbag, it is difficult to cause the vehicle to play a role at a critical moment.
