B007F code meaning
Passenger Seat Belt Pretensioner C Deployment Control
What B007F means
B007F covers the passenger's third (C) pretensioner and is the best-documented code of this series. Mercedes lists B007F13 as an open in the squib of the front passenger's emergency tensioning retractor (A-, CLA- and GLB-Class). FCA uses the same slot for the same part: STAR case S2008000193 for the 2020–2021 Ram 1500 links B007F-2B to a loose or spread plug of the retractor down at the passenger-side B-pillar, repaired with kit 68148100AA, and case S2008000137 for the 2020 Jeep Grand Cherokee reports B007F-11, a short to ground, from a body harness pinched by B-pillar trim. The retractor is a pyrotechnic unit that rewinds the webbing in a crash. With B007F set, the airbag lamp is on and the passenger's shoulder belt lacks pretensioning.

What to do next
- Note B007F 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.
