Code B0088:02 Description

The B0088:02 diagnostic trouble code indicates that there is a short to ground in the right rear side impact sensor circuit. The side impact sensor is a crucial component of the vehicle's safety system, as it detects impacts on the side of the vehicle and sends signals to the airbag control module to deploy the side airbags if necessary. A short to ground in this sensor can compromise the accuracy of the sensor's readings, potentially leading to improper deployment or non-deployment of the side airbags during a side impact collision.

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.
