B00C6 code meaning
Passenger Seat Recline Position Restraints Sensor
What B00C6 means
B00C6 concerns the sensor that reports how far the passenger seat back is reclined. It appears neither in any public carmaker list nor in NHTSA bulletins. On the passenger side the angle matters mainly for classification, because a reclined back carries part of the occupant's weight. A patent filed in 1997 gives numbers: a cushion sensor read 42, 39 and 27 lb for a 60 lb child at three recline settings and 74, 64 and 49 lb for a 120 lb adult, so a recline sensor feeds a lookup table; there, below about 95 lb the bag is suppressed. A 2010 Delphi patent corrects bladder pressure with a backrest angle from an accelerometer or potentiometer. Without this input a small adult may be taken for a child. B00C6 lights the airbag lamp.
B00C6 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B00C6
- Airbag warning lamp on
- Passenger airbag off lamp may light for an adult sitting with the seat back reclined
- Safety note: airbag system; work on seat back and sensor only de-energised (ignition off, battery off, wait time), relearn or calibrate afterwards, specialist workshop only
Common causes of B00C6
- Most likelyLead to the recline sensor stretched or broken at the seat back hinge
- PossibleRecline potentiometer or inclination sensor worn or faulty
- Less likelyAngle reference not learned after replacing the seat back or the sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00C6 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). |
| C6 | The exact fault in that area. |
What to do next
- Note B00C6 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.
Questions about B00C6
What does B00C6 mean?
B00C6 means "Passenger Seat Recline Position Restraints Sensor". B00C6 concerns the sensor that reports how far the passenger seat back is reclined. It is a generic code, so it means the same on every make.
Is it safe to drive with B00C6?
B00C6 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B00C6 fail an emissions test?
B00C6 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B00C6 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B00C6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
