Drive cycleNot required
Limp modeNo

B00F2 covers the inflatable belt at the left outer seat of row two, the position where such belts actually reached production. Ford offered them from the 2011 Explorer; its 2018 owner's manual puts the bag into the shoulder part of the belts at both outer seats in row two, filled with cooled gas at lower pressure, deployed in frontal, side and rollover crashes and monitored by the same module and lamp as the front belts. Ford itself logs faults under its own codes B141B/B141C: programme 21B11 (Explorer 2014–2016) traces them to damaged seat harness wires at the rear inflatable belt connector. Mercedes-Benz fits its beltbag to the outer rear seats of the S-Class. Neither publishes B00F2. Airbag lamp on when set.

Likely causes

Internal wire damage in the second-row seat harness at the belt connector (Ford programme 21B11)
Plug of the inflator under the left rear seat loose after folding or removing the seat
Fault in the belt inflator igniter

Symptoms

  • Airbag warning light on
  • Left rear inflatable belt may not deploy in a crash
  • Safety note: the belt holds a stored-gas or pyrotechnic inflator – battery off, wait time, work only at a specialist workshop
