Code B1806 2017 Toyota RAV4 Description
The B1806 diagnostic trouble code (DTC) for the 2017 Toyota RAV4 indicates an open in the front passenger side squib circuit. In simpler terms, this means there is a problem with the electrical circuit that controls the front passenger side airbag system. The squib is a component within the airbag system that initiates the deployment of the airbag in the event of a collision. An open circuit in this part of the system can prevent the airbag from deploying properly, potentially putting the front passenger at risk in the event of an accident.

- Faulty front passenger side squib circuit.
- Damaged or corroded wiring in the airbag system.
- Loose or poor connection in the airbag circuit.
- Malfunctioning airbag control module.
- Previous collision or impact that damaged the airbag system components.
Symptoms of B1806 2017 Toyota RAV4
- Airbag warning light illuminated on the dashboard.
- Front passenger airbag may not deploy in a collision.
- Diagnostic trouble code B1806 stored in the vehicle's computer system.

How to Fix B1806 2017 Toyota RAV4
- Begin by diagnosing the specific cause of the open circuit, using a multimeter to test the continuity of the squib circuit and inspecting the wiring for any signs of damage.
- If a faulty squib circuit is identified, it will need to be replaced with a new component to restore proper functionality.
- Repair any damaged or corroded wiring in the airbag system to ensure a reliable connection.
- Check and secure any loose connections in the circuit to prevent future issues.
- Clear the diagnostic trouble code from the vehicle's computer system and test the airbag system to verify that the repair was successful.

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.
