B00E0Third Row Left Seat Belt Pretensioner B Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B00E0 points to a second pretensioner stage (B) on the left seat of the third row. Such a stage would be an extra device next to the retractor, typically a lap or anchor tensioner that pulls on the lower belt end. No carmaker publishes B00E0. Mercedes-Benz, which does fit third-row tensioners (the 2017 GLS manual lists them for every third-row belt), logs the left third-row retractor under B00E7 in topic LI54.21-P-070658, i.e. on the C slot, and never names a B stage back there. GM describes anchor units only for front seats, and Joyson pairs its lap pretensioner with a retractor unit against submarining. A stored code lights the airbag lamp; the stage is treated as not available.
