Safety Belt Retractor Pretensioner
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
As part of the supplemental restraint system (SRS), the driver and front passenger safety belt retractors are equipped with pretensioners. The safety belt retractor pretensioners are pyrotechnic devices integrated to the driver and passenger safety belt retractor assemblies. The safety belt retractor pretensioners work in conjunction with the safety belt buckle pretensioners and control the tension of the driver and passenger safety belts in the event of a deployable collision. The RCM monitors the readiness of the safety belt retractor pretensioners. The RCM uses this information and all other information provided by the restraints system to determine what action is to be taken.
