B0028 ACURA Description

The Driver Side Airbag is located in the center of the steering wheel. The front passenger side airbag is located in the dashboard on the front passenger side. The airbag modules adopt dual inflators for the driver side and/or the front passenger side airbag according to the specifications. The dual inflators increase airbag effectiveness by properly adjusting the timing when the two inflators are ignited (together or sequentially) referring to the collision speed or collision impact.

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.
