Notes

  • Always disconnect the battery terminals, press the horn twice then wait at least 10 minutes before working on airbags. 
  • Don't Probe The Airbag With Your Multi-Meter
  • Always handle airbags with care. Do not drop an airbag. 
  • Many airbags are designed to destroy the protective covers they’re concealed in, such as plastic A-pillar or B-pillar trim, seat bolsters, passenger dashboard covers, pillar or B-pillar trim, seat bolsters, passenger dashboard covers, pillar trim, seat bolsters, passenger dashboard covers, etc. 
  • Airbags deploy with significant force and can not only damage peripheral and supporting parts, but the damage may not be apparent. This can include electronics, collapsible steering columns, ignition and brake interlocks, instruments, glass and more.
  • Airbag sensors, which trigger the deployment, are often single-use designs, using a sliding, inertia-driven ball and a membrane. Once activated, these sensors will need replacement too to operate in case of another accident.
  • Accidents that are serious enough to activate the airbags will often trigger the active restraints. That means that the seat belts will also need to be inspected and possibly replaced. Many vehicle restraints use a small explosive charge to tighten the belt by a few inches in an accident. Once that retractor is activated, it must be replaced.
