Adaptive SEATBELT Force Limiter (Only XC60 Or USA/CDN)
Never use an ohmmeter or similar tool to test airbags, inflatable curtains adaptive belt force limiters, adaptive steering column or belt tensioners. Disconnect airbags, inflatable curtains, adaptive belt force limiters, adaptive steering column or belt tensioners before testing them. Failure to do so may result in accidental deployment, which in turn could result in serious injury or death.
The adaptive belt force limiters improve the function of the seat belt in the event of a head-on collision that triggers airbag deployment. There are two adaptive belt force limiters in the vehicle. These are integrated in the belt retractors of the driver and front passenger seat and sit at shoulder height. The two adaptive belt force limiters are electrically separated from each other. They have a pyrotechnical charge that upon deployment reduces belt force to reduce the forces against the chest.
The adaptive belt force limiter, belt retractor, belt retractor sensor and belt tensioner are mounted in a unit. If there is a fault in any of these components, the entire unit must be replaced.
