Code B1828 2018 Toyota RAV4 Description
The B1828 diagnostic trouble code (DTC) for a 2018 Toyota RAV4 indicates a "Short to Positive in Side Squib Left Circuit." This code specifically points to an issue with the side airbag module on the left side of the vehicle. The side squib is a component of the airbag system that helps deploy the side airbag in the event of a collision. A short to positive in this circuit means that there is an unintended connection between the positive power supply and the side squib, which can potentially lead to the airbag deploying unexpectedly or not deploying at all during a crash.

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.
