B00DF code meaning
Passenger Restraints Disable Switch
What B00DF means
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.
B00DF at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.2 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B00DF
- 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
Common causes of B00DF
- PossibleSwitch circuits present in the harness of a vehicle without the switch, damaged or picking up faults (FCA B00DF-95)
- PossibleKey switch worn or its lead open or shorted
- Less likelyRestraint module software counter or configuration error (Ford B00DF:4A)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00DF means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| DF | The exact fault in that area. |
What to do next
- Note B00DF 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.
