Code B1805 2017 Toyota RAV4 Description
The B1805 diagnostic trouble code for a 2017 Toyota RAV4 specifically indicates a "Short In Front Passenger Side Squib Circuit." In simpler terms, this code points to a potential issue with the airbag system on the front passenger side of the vehicle. The term "squib" refers to the electrical component within the airbag system that initiates the deployment of the airbag in the event of a collision. A "short" in this context means that there is an unintended connection between two points in the circuit, which can cause a malfunction in the airbag deployment system.

- Faulty Squib Circuit: A short in the front passenger side squib circuit can be caused by a damaged or faulty electrical component within the airbag system.
- Loose or Corroded Connectors: Poor connections or corrosion in the wiring harness or connectors can disrupt the flow of electricity in the squib circuit.
- Impact or Collision: A previous impact or collision that damaged the front passenger side of the vehicle could have caused a short in the squib circuit.

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.
