B00E8 code meaning
Third Row Center Seat Belt Pretensioner C Deployment Control
What B00E8 means
B00E8 closes the C row of the table with the centre seat of the third row. No manufacturer publishes it, and the one public list that uses this block, Mercedes-Benz LI54.21-P-070658, stops at a left and a right third-row retractor (B00E7, B00E6). A centre tensioner in row three would mostly appear in large vans or SUVs with a three-seat rear bench. Joyson's retractor pretensioner is compact enough to go into a seat frame, which is where a centre unit would have to live. IIHS frontal tests of 2019 compared rear dummies in vehicles with standard belts and with tensioners plus load limiters, and noted such rear countermeasures are not yet widespread. If B00E8 is set, the airbag lamp is on and the centre belt is not tightened.
