Code B2235 Ford Description
The B2235 Ford code indicates that there is a low resistance in the airbag passenger inflator circuit on the squib side. The squib is the component responsible for deploying the airbag in the event of a collision. When the resistance in the circuit is too low, it can prevent the airbag from deploying properly or, in some cases, cause it to deploy unexpectedly. This can pose a significant safety risk to the vehicle occupants as the airbag may not provide the necessary protection in the event of a crash.
Common Causes of B2235 Ford
- Damaged wiring in the airbag passenger inflator circuit.
- Faulty squib (airbag inflator).
- Malfunctioning airbag control module.
- Corrosion or poor connections in the circuit.
- Impact or collision that damaged the airbag system components.
Symptoms of B2235 Ford
- Airbag warning light illuminated on the dashboard.
- Intermittent or constant beeping sound indicating an airbag system fault.
- Inability to turn off the airbag system warning light.
- Airbag system may not deploy in the event of a crash.
- Unintended airbag deployment.
How to Fix B2235 Ford
- Begin by diagnosing the specific cause of the low resistance in the airbag passenger inflator circuit using a diagnostic scanner.
- Inspect the wiring and connections in the circuit for any damage or corrosion. Replace any damaged wiring.
- Test the squib (airbag inflator) for proper functionality. Replace if necessary.
- Check the airbag control module for faults and replace if needed.
- Clear the diagnostic trouble codes from the vehicle's system and perform a test to ensure the airbag system is functioning correctly.

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.
