The Tips for Car Airbag Repair

The airbag system is an integral airbag module composed of an airbag and an inflator (gas generator), a collision sensor system that senses a collision and sends out a deployment command to the airbag module, and a wiring harness that transmits the signal from the sensor. So if it is car airbag repair, what should I pay attention to?

Airbag Inflator for Passenger

(1) Non-professional airbag maintenance personnel are not allowed to inspect and repair airbags.

(2) Before starting the maintenance, the contents of the clock, anti-theft system and audio system should be recorded. Vehicles with electric tilt and telescopic steering system, electric vehicle exterior mirror, electric seat and electric shoulder strap system should be repaired After that, new adjustments and settings should be stored. The use of backup power sources outside the vehicle is prohibited.

(3) When performing maintenance work on the airbag, the ignition switch should be placed in the locked position, and the negative electrode of the battery should be disconnected first, and wait for 3 minutes. If the indicator lamp operates abnormally, wait for 10 minutes before operating to avoid accidents.

(4) When the airbag is removed and placed, the cushion (soft surface) should be facing up and away from water, oil, grease, detergent, etc.

(5) The methods of reading and eliminating the fault codes of the airbag system of different car models should be distinguished.

(6) It is forbidden to heat the airbag or igniter of the airbag or attempt to open it with tools.

(7) When disassembling, pay attention to protecting the airbag components, especially the connectors. Before electric welding, the connector near the multi-function switch under the steering column should be removed to protect the airbag system.

(8) After disassembling the detonated airbag, you should wash your hands. If impurities get into your eyes, you should rinse them with clean water immediately to prevent damage.

(9) The components of the airbag must be packaged in the original factory and the grades must be consistent. When the sensor mounting frame has been deformed, a new sensor must be replaced regardless of whether the airbag has exploded or not. At the same time, the sensor installation position must be repaired so that the sensor housing direction mark faces the front of the car. All the airbags that have been exploded must be replaced with new ones.
