Code B1823 2018 Toyota RAV4 Description

The B1823 diagnostic trouble code (DTC) for a 2018 Toyota RAV4 indicates a "Short to Positive in Side Squib Right Circuit." This code specifically points to an issue with the side airbag system on the right side of the vehicle. The side squib refers to the airbag inflator module, which is responsible for deploying the side airbag in the event of 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.
