B00F4 covers the inflatable belt on the outboard right seat of row two. The hardware exists in series cars, but the code is not documented by any maker. Ford's Explorer (2014–2016) logs belt faults as B141B and/or B141C; supplement 2 of programme 21B11 (June 2022) stresses checking those codes first and allows a separate labour time when both are present, then repositioning or replacing the seat harness pigtail. Mercedes-Benz offers the beltbag on rear belts of the E-Class; its manual warns against routing a child seat through a belt carrying the BELTBAG label. Daimler's 2010 patent places the gas generator at the lower belt anchor and folds the webbing with tear threads. With B00F4 set, the airbag lamp is on.

Likely causes

Worn or broken wires in the right second-row seat pigtail (Ford Explorer 2014–2016)

Inflator igniter faulty

Symptoms
