Code B1800 Scion Description
The B1800 Scion code indicates a short in the driver side squib circuit. In simpler terms, this means that there is a problem with the driver's side airbag system. The squib circuit refers to the electrical circuit that controls the deployment of the airbag in case of a collision. A short in this circuit can prevent the airbag from deploying properly, compromising the safety of the driver in the event of an accident.
Common Causes of B1800 Scion
- Damaged wiring: Worn or damaged wires in the squib circuit can cause a short and trigger this code.
- Faulty airbag module: A malfunctioning airbag module can also lead to a short in the circuit.
- Defective squib circuit component: A faulty component in the squib circuit, such as a sensor or connector, can cause a short.
- Water damage: Water intrusion into the airbag system can corrode wires and connectors, leading to a short in the circuit.
Symptoms of B1800 Scion
- Airbag warning light on the dashboard: One of the most common symptoms of this code is the illumination of the airbag warning light on the dashboard.
- Non-deployment of the driver side airbag: If the airbag does not deploy during a crash, it could indicate a problem with the squib circuit.
- Intermittent airbag deployment: The airbag may deploy unexpectedly or fail to deploy at all, indicating a malfunction in the circuit.
- Faulty horn or cruise control: In some cases, a short in the squib circuit can also affect the operation of the vehicle's horn or cruise control.
How to Fix B1800 Scion
- Diagnostic scan: Begin by using a diagnostic scan tool to retrieve the specific fault codes and identify the exact cause of the short in the driver side squib circuit.
- Inspect wiring and connectors: Thoroughly inspect the wiring and connectors in the squib circuit for any signs of damage or corrosion. Repair or replace any faulty components as needed.
- Test airbag module: Test the airbag module to check for proper functionality. Replace the module if it is found to be defective.
- Clear fault codes: After completing the repairs, clear the fault codes from the vehicle's system to reset the airbag warning light on the dashboard.
- Test airbag system: Finally, test the airbag system to ensure that the driver side airbag deploys correctly in a controlled environment.
Cost to Fix B1800 Scion

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.
