B00B6 code meaning
Driver Seat Recline Position Restraints Sensor
What B00B6 means
B00B6 concerns a sensor that tells the restraint system how far the backrest of the driver seat is reclined. No carmaker documents this code publicly, and the NHTSA bulletin index has no entry for it. Patents show why the angle matters: an ATI patent lets the controller suppress or depower the airbag from seat position, back angle and belt spool-out alone, without looking at the occupant, and a Bosch application derives the tilt from a three-axis accelerometer in the seat back, uses a 45 degree limit to decide which airbags fire and feeds the angle into occupant classification. Autoliv even calibrated its classification mat at several back angles. If B00B6 is stored the module loses that input; the airbag lamp stays on until the sensor or its circuit is repaired.
B00B6 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 B00B6
- Airbag warning lamp on
- Airbag adaptation to a reclined seating position unavailable
- Safety note: airbag system; disconnect seat and sensor plugs only de-energised (ignition off, battery off, wait time); calibrate the sensor after replacement, specialist workshop only
Common causes of B00B6
- Most likelyLead pinched or broken at the seat back hinge, where it flexes with every adjustment
- PossibleInternal fault or loose mounting of the recline sensor
- Less likelySensor or seat back replaced without the required zero setting
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00B6 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). |
| B6 | The exact fault in that area. |
What to do next
- Note B00B6 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 B00B6
What does B00B6 mean?
B00B6 means "Driver Seat Recline Position Restraints Sensor". B00B6 concerns a sensor that tells the restraint system how far the backrest of the driver seat is reclined. It is a generic code, so it means the same on every make.
Is it safe to drive with B00B6?
B00B6 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B00B6 fail an emissions test?
B00B6 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 B00B6 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B00B6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
