Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

  • I was in a wreck and the tech put the above code on service ticket. My dash has a dented looking etch in a rectangle across the passenger side dash. Does this mean the airbag is defective or was somehow slightly triggered? Will it cause any safety issue in the future?

  • What model and year is your vehicle?
    There is not an "Slightly Triggered", your air bag is either good or bad, in your case more than likely defective and it wont deployed if there is an accident. You should have your local dealer inspect the air bag for you.
