B009F code meaning
Right Side Restraints Sensor 6
What B009F means
B009F would be the sixth and last right-hand restraints sensor in the J2012 block. No carmaker documents it publicly with this meaning. The number does appear at GM, but for another part: on 2008–2013 two-mode hybrid Tahoe, Yukon, Escalade, Silverado and Sierra trucks, bulletin PIT4614C ties a no-crank condition with B009F stored in the SDGM gateway to water passing the seal of the HVCID crash sensor for the high-voltage circuit, mounted on the lower radiator support; the sensor and terminals are inspected and replaced. That is a crash switch for isolating the hybrid battery, not an airbag satellite. A genuine sixth right satellite would be an acceleration unit, for example a PSI5-linked Bosch SMA773 sensor on a rear pillar or sill. Its failure lights the airbag lamp.
B009F 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 B009F
- Airbag warning lamp on
- On GM two-mode hybrids, no crank or a Service Hybrid message instead
- Safety note: airbag and, on hybrids, high-voltage system; disconnect plugs only de-energised; after a sensor change have it checked or initialised, specialist workshop only
Common causes of B009F
- Most likelyDamaged rear body harness or plug to the sixth right sensor
- PossibleInternal fault of the sixth right acceleration satellite
- Less likelyOn GM two-mode hybrids, water or corrosion at the high-voltage impact detection sensor (different meaning, PIT4614C)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B009F 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). |
| 9F | The exact fault in that area. |
What to do next
- Note B009F 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 B009F
What does B009F mean?
B009F means "Right Side Restraints Sensor 6". B009F would be the sixth and last right-hand restraints sensor in the J2012 block. It is a generic code, so it means the same on every make.
Is it safe to drive with B009F?
B009F does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B009F fail an emissions test?
B009F 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 B009F to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B009F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
