Code B0086:02 Description

The B0086:02 diagnostic trouble code indicates that there is a short to ground in the right front side impact sensor circuit. The side impact sensor is a crucial component of the vehicle's safety system, designed to detect side collisions and deploy the side airbags to protect the occupants. A short to ground in the sensor circuit can prevent the sensor from functioning properly, potentially leading to the airbags not deploying in the event of a side 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.
