B00F5 code meaning
Third Row Left Inflatable Seat Belt Deployment Control
What B00F5 means
B00F5 opens the third-row part of the inflatable-belt block with the left seat; B00F6 (centre) and B00F7 (right) follow. No manufacturer documents B00F5, and the known systems stop at row two: Ford's Explorer has its inflatable belts only at the second-row outer seats, even though it has a third row, and Mercedes offers the beltbag for rear belts of S- and E-Class (outer seats in the S-Class). The inflatable belt in NHTSA's 2021 test series was likewise a second-row belt. Technically a third-row unit would work like the others, with a bag in the shoulder webbing and an inflator near buckle or anchor, as the Autoliv patent outlines. If the code is stored, the airbag lamp is on and that belt will not inflate.

What to do next
- Note B00F5 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
