B0092 Code: Causes, Symptoms, Diagnosis, and Repair Guide

The B0092 diagnostic trouble code (DTC) indicates a fault in the Supplemental Restraint System (SRS). On many vehicles, this code is associated with the passenger presence/occupant detection system or another manufacturer-specific airbag circuit. Because B-codes are manufacturer-specific, the exact definition varies by vehicle make and model.

What Does Code B0092 Mean?

Code B0092 is stored when the SRS control module detects an abnormal signal from the passenger occupancy detection system or a related airbag circuit. The problem may result from an open circuit, short circuit, excessive resistance, sensor failure, or communication issue. When this occurs, the Airbag or SRS warning light illuminates, and the passenger airbag may be disabled.

Common Causes

  • Faulty passenger occupancy sensor.
  • Loose or damaged seat wiring harness.
  • Poor electrical connections or corroded connectors.
  • Damaged seat pressure sensor or seat cushion sensor.
  • Defective Passenger Presence Module (if equipped).
  • Faulty SRS control module.
  • Previous accident damage or improper repairs.

Symptoms

  • Airbag or SRS warning light is illuminated.
  • Passenger Airbag OFF indicator remains on unexpectedly.
  • Stored B0092 diagnostic trouble code.
  • Passenger airbag may not deploy during a collision.
  • Additional SRS fault codes may also be present.

How to Diagnose Code B0092

  1. Read all SRS fault codes using a professional scan tool.
  2. Inspect the passenger seat wiring and connectors.
  3. Check the occupant detection sensor for damage.
  4. Measure circuit continuity and resistance according to the service manual.
  5. Verify operation of the passenger presence module if equipped.
  6. Inspect the SRS control module if no other faults are found.

How to Fix Code B0092

  • Repair or replace damaged wiring.
  • Reconnect or replace faulty electrical connectors.
  • Replace the passenger occupancy sensor if defective.
  • Replace the passenger presence module when necessary.
  • Repair or replace the SRS control module if required.
  • Clear the trouble code and verify the repair.

How Serious Is Code B0092?

B0092 is considered a serious safety-related fault. Although the vehicle usually remains drivable, the passenger airbag system may not function correctly during a collision, increasing the risk of injury.

Estimated Repair Cost

  • Wiring or connector repair: $20–$150
  • Occupancy sensor replacement: $150–$700
  • Passenger presence module replacement: $200–$800
  • SRS control module replacement: $400–$1,500+

Vehicles That May Display Code B0092

B0092 may appear on Chevrolet, GMC, Cadillac, Buick, Ford, Lincoln, Toyota, Lexus, Honda, Acura, Nissan, Infiniti, Hyundai, Kia, Mazda, Subaru, Volkswagen, and other manufacturers that use manufacturer-specific SRS diagnostic codes.

Can You Drive with Code B0092?

The vehicle can usually still be driven, but it is not recommended. The passenger airbag may not deploy correctly until the fault is repaired, reducing occupant protection in the event of an accident.

Conclusion

The B0092 trouble code indicates a fault in the passenger occupant detection or airbag system that should be diagnosed as soon as possible. Repairing the underlying electrical or sensor issue will restore proper SRS operation and ensure maximum safety for vehicle occupants.
