Code B1805 2016 Toyota RAV4 Description
The B1805 code in a 2016 Toyota RAV4 indicates a short in the front passenger side squib circuit. This refers to an issue with the circuit responsible for the deployment of the airbag in the front passenger side of the vehicle. The squib circuit is a crucial component of the vehicle's supplemental restraint system (SRS), designed to deploy the airbag in the event of a collision to protect the occupants.
Common Causes of B1805 2016 Toyota RAV4
- Faulty wiring: One of the most common causes of this code is damaged or frayed wiring in the squib circuit, which can result from wear and tear or external damage.
- Loose connections: Loose or corroded connections in the circuit can also trigger this code, disrupting the flow of electrical signals.
- Faulty squib circuit: A malfunctioning squib circuit component, such as the airbag module or clock spring, can also cause a short and trigger this code.
- Impact damage: In some cases, the code may be triggered by impact damage to the front passenger side of the vehicle, such as a collision or a bump.
- Water damage: Water infiltration into the squib circuit can also cause a short and trigger this code, especially in areas prone to flooding or moisture.
Symptoms of B1805 2016 Toyota RAV4
- Airbag warning light: One of the most common symptoms associated with this code is the illumination of the airbag warning light on the vehicle's dashboard. This light indicates that there is a fault in the airbag system and should not be ignored.
- Non-deployment of airbag: If the code is not addressed, the airbag may fail to deploy in the event of a collision, increasing the risk of injury to the front passenger.
- Intermittent airbag deployment: In some cases, the airbag may deploy unexpectedly or intermittently, which can be dangerous for the occupants.
- Faulty horn or cruise control: A short in the squib circuit can also affect other systems in the vehicle, such as the horn or cruise control, leading to malfunctions.
How to Fix B1805 2016 Toyota RAV4
- Diagnose the issue: The first step in resolving this code is to diagnose the specific cause of the short in the front passenger side squib circuit. This may involve using a diagnostic scanner to read the fault codes and pinpoint the source of the problem.
- Inspect wiring and connections: Check the wiring and connections associated with the squib circuit for any signs of damage, corrosion, or loose connections. Repair or replace any damaged components as needed.
- Test the squib circuit components: Test the airbag module, clock spring, and other components of the squib circuit to ensure they are functioning correctly. Replace any faulty components to resolve the issue.
- Clear the fault codes: Once the repairs are completed, clear the fault codes from the vehicle's system using a diagnostic scanner to reset the airbag warning light.
- Perform a system test: After repairing the squib circuit, perform a system test to ensure that the airbag deploys correctly and the issue has been resolved.
Cost to Fix B1805 2016 Toyota RAV4
The cost of repairing a short in the front passenger side squib circuit can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of parts for this repair can range from $200 to $500, including components such as wiring harnesses, airbag modules, and clock springs. The labor costs for this repair typically range from $150 to $300, with the total repair cost averaging between $350 and $800.

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.
Frequently Asked Questions about B1805 2016 Toyota RAV4 Code

Common symptoms include the airbag warning light staying illuminated and the airbag system being disabled.
3. What causes the B1805 code to appear?
This code is typically caused by damaged wiring, corroded connectors, or a faulty airbag module in the front passenger side squib circuit.
4. Is it safe to drive with a B1805 code in my 2016 Toyota RAV4?
No, it is not safe. The airbag system may be disabled, increasing the risk of injury in a collision.
5. How do I troubleshoot the B1805 code?
Start by inspecting the wiring and connectors in the front passenger side squib circuit for damage or corrosion, then test the airbag module and related components.
6. Can a discharged or weak battery cause the B1805 code?
While unlikely, a weak battery can sometimes cause electrical faults, so it’s worth checking the battery voltage before deeper diagnostics.
7. How much does it cost to fix a B1805 code on a 2016 Toyota RAV4?
Repair costs vary but typically range from $100 to $500, depending on whether the issue is a simple wiring repair or a component replacement.
8. Can I clear the B1805 code without fixing the problem?
Clearing the code without addressing the issue will not resolve the underlying problem, and the airbag light will likely return.
9. Should I replace the airbag module if I get a B1805 code?
Not necessarily. The issue might be with the wiring or connectors. Replace the airbag module only if diagnostics confirm it is faulty.
10. Do I need special tools to diagnose the B1805 code?
Yes, you’ll need an advanced OBDII scanner capable of reading airbag system codes and possibly a multimeter for electrical testing.
