B0088 code meaning
Third Row Right Seat Belt Load Limiter Deployment Control
What B0088 means
B0088 closes the load limiter series with the right third-row seat. No manufacturer documents it with this meaning. If such a squib-switched limiter is fitted, the module tests its loop for opens, shorts and out-of-window resistance like any igniter; an Autoliv patent shows the principle, where gas from a squib releases a blocking ring so the softer torsion section takes over. Some designs avoid the extra loop altogether, such as the Delphi rear-seat retractor that switches mechanically. On GM Global A models (2011 Saab 9-4X) B0088 instead flags the right rear side impact sensor, using the same symptom bytes as its siblings: shorts, open or high resistance, low current, internal failure, wrong part fitted and invalid serial data. A stored code lights the airbag lamp.

Common causes of B0088
- Most likelyOn GM vehicles, right rear side impact sensor or wiring faulty (different meaning)
- PossibleHarness to the right third-row seat strained by seat folding
- Less likelyInternal fault of the right third-row limiter squib
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0088 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 88 | The exact fault in that area. |
What to do next
- Note B0088 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.
