AI DamageB0050 code: Driver Seat Belt Sensor
Code B0050 is named in 3 US owner complaints. Models: 3, model years 2014–2024.
What the code means
Driver Seat Belt Sensor. Generic meaning per SAE J2012 (the same for all makes).
How to read B0050: the letter B means body (including airbags and belts); the second digit 0 marks a generic SAE code shared by all makes; the last three characters 050 identify the specific fault.
Restraint system codes: airbag squibs, belt pretensioners, crash sensors and occupant classification. After a crash with airbag deployment, many makers require the restraint module to be replaced or reset by procedure because it stores crash data. An airbag light on an auction car is not cosmetic: airbags, the module and sensors can cost more than the body repair.

What to do if an auction car has this code
- Ask for a dash photo at start-up: the airbag light must go off after the self-test.
- Check the interior photos for deployed airbags and fired belt pretensioners: replacing the restraint module, airbags and sensors is a large separate part of the estimate.
- Budget a scan with a restraint module read-out: the code alone does not say which part failed.
