B0082 covers the firing loop of the front passenger's switchable belt force limiter. Two manufacturers document this meaning. In the Mercedes A-Class, CLA and GLB, B008213 marks an interrupted igniter of the passenger-side belt force limiter. Ford special service message 51998 covers 2023 Escape, Corsair, Bronco Sport and Maverick that store B0082:1A because of the passenger belt retractor at connector C303B; where a connection fault is found, the retractor and pretensioner assembly is replaced before any wiring repair. Autoliv patents show why retractor and limiter belong together: the pretensioner's own gas can select the higher limiting level. On GM Global A cars (Saab 9-4X) B0082 means the seat belt reminder sensor in the passenger cushion instead. The airbag lamp stays on.

Likely causes

Poor connection at the passenger retractor plug (Ford C303B, SSM 51998)
Raised resistance at the airbag module connector (Mercedes LI54.21-P-070658)
Internal fault of the passenger retractor and limiter assembly

Symptoms

  • Airbag warning lamp on
  • Passenger belt cannot switch its force limiting level in a crash
  • Safety note: pyrotechnic retractor at the passenger B-pillar; work only de-energised (battery off, wait time) at a specialist workshop
