Code B0084:0F Description

The B0084:0F code indicates an erratic signal from the right front impact sensor in the vehicle's safety system. Impact sensors are crucial components that detect collisions or accidents and trigger the deployment of airbags to protect occupants. When the right front impact sensor is sending erratic signals, it means that the sensor may not accurately detect impacts or may trigger airbag deployment when it is not necessary. This can pose a significant safety risk to the vehicle's occupants as the airbags may not deploy when needed or deploy unexpectedly, causing potential injuries.

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.
