B00DF is set for the key switch that lets the passenger airbag be turned off by hand. FMVSS 208 S4.5.4 allowed it on vehicles built before September 2012 with no forward rear seats or a short rear row; it must take the key, stay apart from the ignition and keep the bag off until switched back, and 49 CFR 595.5 governs retrofits under an NHTSA letter. Two makers use the code. FCA describes B00DF-95, incorrect assembly, on 2018–2021 Jeep Wrangler built without the on/off switch option CGZ: unused dash harness circuits R167/R168 should be checked and isolated at the ORC. Ford reports B00DF:4A after self-tests on 2024 Nautilus, from an internal counter fixed over the air, and on 2026–2027 Transit, cleared with FDRS. A real fault lights the airbag lamp.

Likely causes

Switch circuits present in the harness of a vehicle without the switch, damaged or picking up faults (FCA B00DF-95)
Key switch worn or its lead open or shorted
Restraint module software counter or configuration error (Ford B00DF:4A)

Symptoms

  • Airbag warning lamp on
  • Passenger airbag does not follow the switch position, or the off lamp disagrees with it
  • Safety note: passenger airbag state uncertain; no rear-facing child seat on that seat until checked, wiring and switch only de-energised (ignition off, battery off, wait time), specialist workshop
