B00F3 refers to an inflatable belt at the centre seat of the second row. No manufacturer documents the code, and the known systems leave this seat out: Ford's 2018 Explorer manual limits its inflatable belts to the outermost second-row positions, and Mercedes fits its beltbag to the outer rear belts (S-Class manual 2017); the E-Class manual of the same year lists the belt air bag as a frontal-impact device. A centre version would be harder to package because the gas usually enters at the buckle or lower anchor; NHTSA's belt tensile study notes that the 2011 Explorer belt needed a retractor in the lap loop because its inflator was attached to the buckle. If set, the airbag lamp is lit.

Likely causes

Restraint module configured for a centre inflatable belt not present in the vehicle
Connector at the centre buckle inflator under the bench disconnected
Igniter of the centre belt inflator open or shorted

Symptoms

  • Airbag indicator remains on
  • Rear centre belt would not inflate in a crash
  • Safety note: pyrotechnic or stored-gas inflator – only work with the battery disconnected and the wait time observed, at a specialist workshop
