B0085Second Row Right Seat Belt Load Limiter Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B0085 points to the igniter circuit that would change the force level of the right rear belt. No maker documents it with that meaning. Joyson offers dual-stage limiters with degressive or adaptive behaviour, and an Autoliv patent switches from the stiff to the soft torsion section when the controller fires a squib once cabin deceleration crosses a threshold; in a rear seat such a loop would be watched like any other squib. IIHS rear-seat work found the right rear position tested less often than the left (16 against 27 runs). In practice, B0085 on a GM Global A car (Saab 9-4X 2011) is the left front side impact sensor, reported for shorts, opens, current above 23 mA, internal failure, a wrong part or invalid serial data. Only the make tells which part is meant.
