Safety Belt Retractor Pretensioner

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The safety belt retractor pretensioner removes excess slack from the safety belt webbing. The pretensioner is activated by the RCM when the module detects a crash event force exceeding a programmed limit.
