B0087Third Row Center Seat Belt Load Limiter Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B0087 would flag the igniter circuit of an adaptive belt force limiter on the centre position of row three. That combination is close to theoretical: no carmaker documents the code, and NHTSA's 2013 study dates universal fitment of load limiters (by model year 2007) only for the front outboard seats. Joyson describes how such a unit works, with linear limiters tuned to a vehicle's crash pulse and dual-stage versions for adaptive or degressive force. On GM Global A vehicles (2011 Saab 9-4X) B0087 means the left rear side impact sensor. GM sets it after ten seconds of a fault, or when the module hears nothing from the sensor for over 375 ms. A history code there clears after 100 fault-free ignition cycles. Check the make first.
