Code B1875 Description
The B1875 code indicates a short in the passenger side front seat cushion squib circuit. The seat cushion squib is a component of the airbag system in the vehicle. When this circuit has a short, it means that there is an electrical issue that could prevent the airbag from deploying properly in the event of a collision. This can pose a serious safety risk to the vehicle occupants as the airbag may not provide the necessary protection in a crash.
Common Causes of B1875
- Damaged wiring: One of the most common causes of a short in the seat cushion squib circuit is damaged wiring. Over time, the wiring in the vehicle can become worn or frayed, leading to electrical issues that can trigger the B1875 code.
- Faulty connectors: Another possible cause of this issue is faulty connectors in the seat cushion squib circuit. If the connectors are damaged or corroded, it can prevent the proper flow of electricity and result in a short circuit.
- Malfunctioning seat cushion squib: The seat cushion squib itself may be malfunctioning, causing a short in the circuit. This component can wear out over time or be damaged due to external factors, leading to electrical issues.
- Water damage: Water intrusion into the seat cushion squib circuit can also cause a short. This can happen if there is a leak in the vehicle or if water seeps into the wiring harness, disrupting the electrical connections.
Symptoms of B1875
- Airbag warning light on the dashboard: One of the most common symptoms of this issue is the illumination of the airbag warning light on the dashboard. This light indicates that there is a problem with the airbag system, which could be caused by a short in the passenger side front seat cushion squib circuit.
- Non-deployment of airbag: In the event of a collision, the airbag may fail to deploy if there is a short in the seat cushion squib circuit. This can result in increased risk of injury to the passenger in the front seat.
- Intermittent airbag deployment: Another possible symptom is intermittent deployment of the airbag, where the airbag may deploy unexpectedly or fail to deploy when needed. This can be a dangerous situation that requires immediate attention.
- Faulty seatbelt pretensioners: A short in the seat cushion squib circuit can also affect the operation of the seatbelt pretensioners, which work in conjunction with the airbags to restrain the occupants during a collision. If the seatbelt pretensioners do not function properly, it can compromise the overall safety of the vehicle.
How to Fix B1875
- Diagnose the issue: The first step in repairing the B1875 code is to diagnose the exact cause of the short in the passenger side front seat cushion squib circuit. This may involve using a diagnostic scanner to retrieve the fault codes and inspecting the wiring and connectors for any visible damage.
- Repair or replace damaged wiring: If damaged wiring is the culprit, it will need to be repaired or replaced. This may involve soldering the damaged wires or replacing the entire wiring harness, depending on the extent of the damage.
- Check and clean connectors: Faulty connectors should be checked and cleaned to ensure they are making proper electrical connections. If any connectors are damaged, they may need to be replaced.
- Test the seat cushion squib: The seat cushion squib should be tested to determine if it is functioning correctly. If it is found to be faulty, it will need to be replaced with a new unit.
- Clear the fault codes: Once the repairs have been completed, the fault codes should be cleared from the vehicle's system using a diagnostic scanner. This will reset the airbag system and allow it to function properly.

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.
