1, the airbag may be shorter than the actual life of the vehicle
The figure expired airbag assembly with the bomb out
theoretically automobile airbag design life and the life of the vehicle are consistent. However, due to lack of design standards, the actual life of the airbag is not so long. Although there is no definite shelf life, but even without airbags detonate after 8-10 years of use, quality is difficult to guarantee.
2, warning lights of the airbag, but can not find airbag system
is inserted into the key to unlock a twist, a second twist the key sub-powered car is about 5 seconds and let the vehicle electronics checks on their own time, the third time is the key to twist the ignition.
However, after the ignition was found airbag lamp is lit or how is it? Airbag lights or is a clue that the airbag sensor fault, either the data read error, either The airbag has failed came up. This time we first want the easiest place to start, check the number of safety airbags.
3, the airbag electronic control unit may fail due to false positives
where
Sometimes due to the site, the angle, system failure, the air bag after the impact occurred no pop happens sometimes. But pop airbags for no reason, because more difficult to say clearly, this requires the vehicle to accurately identify technical conclusions. Simply look, if not the quality of the air bag, that is, after the failure of the relevant electronic control unit misrepresented the ignition command.
For example, rubbing the body along the road, or a splash of stone hit sensitive parts, so that the electronic system is mistaken for a major collision, the airbag will pop up.
The reason why such a situation, it may be quite large poor vehicle maintenance, in addition to their tamper with the car circuit, converted new device that destroyed the airbag system other than , older vehicles are not professional examination may also cause such incidents.
4, carefully airbag failureImproper use of the seat cover will death
Safety airbag on the number of different models are different, generally have dual front airbags, side airbags, head airbag and a knee airbag, the airbag which is most susceptible to side airbag. Why side airbags vulnerable? Usually side air bag disposed inside a seat, the side airbag has a high-class car vehicle usually, the owner put the seat cover and will generally avoid cleaning leather seats. The problem lies here
Now most cars uses a classification of the airbag detonation. First airbag detonation sensor according airbag case of vehicle collision, the airbag rating of about 40 percent of the first detonation effect gas volumetric capacity (the airbag is by internal gas cushion); That is, power is not detonated large, did not play a destructive effect on seat covers, airbag squib inflate results directly to the seat covers fully offset.
5, going airbag troubleshooting authorized shop 4S
The airbag indicator flashes or remains lit long do not put out in 6-8 seconds after the vehicle is started, it means airbag failure; during operation of the vehicle, the airbag indicator light flashes 5 seconds long, said airbag fails to be promptly 4S shop inspection process. During startup of the vehicle will have a self-test procedure OBD, the detection system includes an airbag. After 4S shop requires every vehicle traveling 10,000 to 20,000 km, you should check the airbag 4S shop and its auxiliary components, can also be maintained in the vehicle to store the airbag 4S detected.
6, seat too far forward in case of air-bag deployment is dangerous
especially girls generally like to be moved to the very front seat of the car, so playing direction the arms would be more relaxed, in fact, potentially dangerous. On a driver, if it is too close or too far away from the steering wheel, the passenger called off-site, and the air bag has a strong position from the harmful effects of the occupant.
The driver seat airbag danger zone is in the range of the pneumatic system ahead of 5-8 cm. Therefore, keep a distance of 25 cm with a driver’s airbag can allow himself to be in absolutely safe area, this distance should be from the steering wheel to the center position to measure the sternum.
