When the resistance in the circuit is too low, it can prevent the airbag from deploying properly or at all, compromising the safety of the vehicle occupants in the event of an accident.
Common Causes of B2235 Mercury
- Faulty wiring or connectors in the airbag system.
- A defective passenger airbag squib.
- Malfunctioning airbag control module.
- Corrosion or damage to the electrical connections in the system.
- Impact or collision that may have damaged the airbag system components.
Symptoms of B2235 Mercury
- Airbag warning light illuminated on the dashboard.
- Inability to turn off the airbag warning light even after resetting it.
- Intermittent or non-deployment of the passenger side airbag.
- Diagnostic trouble code B2235 stored in the vehicle's computer system.
How to Fix B2235 Mercury

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.
