B00D1 code meaning
Passenger Seat Belt Indicator
What B00D1 means
B00D1 covers the passenger seat belt warning. Unlike the driver warning, it only makes sense if the car knows the seat is occupied, so it leans on occupant sensing. No carmaker documents the code. Ford's 2014 F-150 uses the passenger sensing system to decide who gets Belt-Minder reminders: above 6 mph and after 1 to 2 minutes, lamp and chime come on for six seconds every 25 seconds for about five minutes. Honda's 2013 Fit lights the passenger warning about 6 s after ignition-on but not for a child or slight adult whom the weight sensors miss. Mazda saw the passenger warning come on for an empty seat holding a laptop or phone. FMVSS 208 S7.5 requires a passenger warning visible to the driver from September 2028. B00D1 points to the lamp side, not the buckle.

What to do next
- Note B00D1 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.
