B00E2 Third Row Center Seat Belt Pretensioner B Deployment Control

B00E2 would report the firing circuit of a B-stage tensioner at the centre seat of the third row. This is about the rarest slot in the pretensioner table: a centre seat in row three is uncommon, and a second tensioner stage on it even more so. No manufacturer documents the code. For comparison, the third-row tensioners in Mercedes vehicles are listed only as left and right retractor loops (B00E7/B00E6 in LI54.21-P-070658), and the GLS manual of 2017 likewise speaks of retractor tensioners. A B stage would act on the lap section, as Joyson's lap pretensioner does in combination with a retractor. If the code appears, check first whether the module's equipment coding matches the seats actually fitted.

Likely causes

Module variant coding expects a centre B stage that is not installed
Plug under the third-row centre seat disconnected after seat removal
Squib of the centre lap tensioner open or shorted internally

Symptoms

  • Airbag indicator stays on after the self-test
  • Centre occupant of the third row may lack lap-belt tensioning in a crash
  • Safety note: pyrotechnic restraint component – disconnect the battery, wait the specified time and have the work done by a specialist
