B009C code meaning
Left Side Restraints Sensor 6
What B009C means
B009C is the sixth and last left-side slot in the J2012 sensor block. No carmaker documents this code publicly. Real vehicles show how many side satellites are usual: FCA's 2019 Jeep Cherokee recall 19V-449 lists two engine bay sensors and four for B- or C-pillar positions, three per side at most, and FCA files those pillar units as B2761 to B2765 rather than in the B009x block. A sixth left sensor would therefore suit only long vans, buses or vehicles with several rear rows, where Bosch's option of satellites in the rear body also fits. If B009C appears, check first which sensor the maker assigns to it; a scan tool reading on a car with fewer sensors may point to a wrong module configuration. The airbag lamp lights.
B009C 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 B009C
- Airbag warning lamp on
- Side impact sensing at the rear left is reduced
- Safety note: airbag system; disconnect the battery and keep the wait time, then have it diagnosed at a specialist workshop
Common causes of B009C
- PossibleAirbag module configured for more side sensors than are fitted
- PossibleDamaged rear body harness or plug to the sixth left sensor
- Less likelyInternal fault of the sixth left satellite
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B009C 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). |
| 9C | The exact fault in that area. |
What to do next
- Note B009C 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 B009C
What does B009C mean?
B009C means "Left Side Restraints Sensor 6". B009C is the sixth and last left-side slot in the J2012 sensor block. It is a generic code, so it means the same on every make.
Is it safe to drive with B009C?
B009C does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B009C fail an emissions test?
B009C 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 B009C to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B009C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
