Safety Belt Buckle Switch
WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. 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 passenger safety belt buckles are equipped with a Hall-effect switch. The safety belt buckle switches indicate to the restraints control module (RCM) whether the safety belt buckles are buckled or unbuckled.
The RCM uses this information in determining the deployment rate of the dual-stage driver and passenger air bag modules.
The safety belt buckle switches are also used for the driver safety belt warning system and the driver and passenger belt minder. Refer to SAFETY BELT SYSTEM .
