B00B5 code meaning
Driver Seat Track Position Restraints Sensor
What B00B5 means
B00B5 reports a fault of the driver seat track position sensor, which tells the airbag module whether the seat is pushed far forward toward the steering wheel. FCA uses it with exactly this meaning: GPOP tech tips for the Dodge Dart (PF), Jeep Cherokee (KL) and Chrysler 200 (UF) name B00B5-13, an open circuit, among codes to clear with engineering before replacing the restraint controller, and a 2024 tip for the Pacifica and Voyager (RU) asks for wiring, plug and low voltage checks first. Allegro describes the usual hardware, a two-wire Hall switch that the steel track shields from a magnet as it passes, giving zones. Honda lowers driver airbag force in the forward zone. Saab 9-3/9-5 file this sensor as B0084 and then disable the second airbag stage. The airbag lamp lights.
B00B5 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B00B5
- Airbag warning lamp on
- Driver airbag may fire without seat position adjustment (e.g. second stage locked out)
- Safety note: airbag system; unplug the seat and sensor connectors only de-energised; after replacing the sensor check its position output/calibration, specialist workshop only
Common causes of B00B5
- Most likelyOpen circuit or bent/corroded pins in the seat harness to the track sensor (FCA subtype -13)
- PossibleSensor loose or wrongly positioned on the seat track, so the Hall switch no longer sees the track edge
- Less likelyLow system voltage (FCA asks to check this before replacing the controller)
- Less likelyInternal fault of the Hall-effect seat track sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00B5 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). |
| B5 | The exact fault in that area. |
What to do next
- Note B00B5 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 B00B5
What does B00B5 mean?
B00B5 means "Driver Seat Track Position Restraints Sensor". B00B5 reports a fault of the driver seat track position sensor, which tells the airbag module whether the seat is pushed far forward toward the steering wheel. It is a generic code, so it means the same on every make.
Is it safe to drive with B00B5?
B00B5 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B00B5 fail an emissions test?
B00B5 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 B00B5 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will B00B5 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
