B00E0 code meaning
Third Row Left Seat Belt Pretensioner B Deployment Control
What B00E0 means
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.

What each part of B00E0 means

| E0 | The exact fault in that area. |
What to do next
- Note B00E0 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.
