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.

Likely causes

Retractor plug at the lower passenger-side B-pillar loose or with spread terminals (FCA S2008000193)
Body harness pinched between B-pillar trim retainer and body (FCA S2008000137)
Internal fault of the passenger retractor pretensioner

Symptoms

  • Airbag warning lamp on, often after recent interior or body repair
  • Passenger shoulder belt not tightened in a crash
  • Safety note: pyrotechnic retractor in the B-pillar; work on it only de-energised (battery off, wait time) and at a specialist workshop
