B0088Third Row Right Seat Belt Load Limiter Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- 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.
