Left Side Restraints Sensor 2
The B0092 code means the vehicle's onboard diagnostic system has detected: Left Side Restraints Sensor 2. This is a serious severity code.
- Keep driving?
- Yes, but fix soon
- DIY difficulty
- hard
- Estimated cost
- $80 - $700 (connector or wiring commonly; sensor mat or seat-sensor replacement at the high end)

What Are the Symptoms of B0092?
- Airbag (SRS) warning light on
- Occupant detection or belt-status behavior wrong (e.g. passenger airbag off with an adult seated)
- No drivability symptom - this is purely a safety-system fault
What Causes B0092? (Most Likely First)
- Faulty or disturbed sensor (this circuit's sensor is often under or inside a seat and gets damaged by movement, spills, or objects beneath the seat) High
- Damaged wiring or corroded connector in the sensor circuit High
- SRS control module input fault Low
Can I Still Drive with B0092?
Yes, but fix soon. B0092 is rated serious severity. It is not an immediate stop-driving fault, but it will not clear itself — book the repair rather than ignoring the light.
Frequently Asked Questions
What does B0092 mean?
B0092 is a generic (ISO/SAE-standardized) restraints code: a fault in the Left Side Restraints Sensor 2 circuit. The SRS module monitors every restraint circuit continuously and sets this when that circuit fails its checks.
Can I keep driving with B0092?
An SRS fault usually means part of the airbag or seatbelt system is DISABLED until repaired - the airbag warning light stays on and that restraint may not deploy in a crash. Never probe deployment-loop (squib) circuits with a test light or ohmmeter; accidental deployment causes serious injury. SRS diagnosis belongs at a qualified shop.
Will the airbag still work with B0092 stored?
Assume no for the affected restraint. With most SRS faults, the module disables the affected circuit (sometimes the whole system) until it is repaired and the code cleared. That is why the warning light stays on.
Mechanics Guide Step-by-step diagnosis
How Do You Diagnose B0092?
-
Read the code and subfault detail with an SRS-capable scan tool.
-
Check for obvious causes first: objects wedged under the seat, unplugged under-seat connectors after cleaning or repairs.
-
Inspect the circuit's wiring per the OEM procedure with the SRS disabled.
-
Follow the OEM calibration/relearn procedure after any occupant-sensor repair - many require a zero-point reset.
