B00F5 Third Row Left Inflatable Seat Belt Deployment Control

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Airbag module coded with a third-row inflatable belt that is not installed
Plug at the left third-row belt inflator disturbed when folding the seat
Defective igniter in the third-row belt inflator

Symptoms

  • Airbag warning lamp on
  • Left third-row inflatable belt not available in a crash
  • Safety note: inflator with explosive igniter – disconnect the battery, wait, and have it handled by a specialist workshop
