Description and Operation: Description
The Emergency Fastening Device (EFD) operates at the same time with the Seat Belt Pretensioner when it satisfies the deployment condition after a collision. It is an auxiliary equipment to prevent a driver and passenger from breaking away by pulling the seat belt toward the anchor side after a collision. It is located near the anchor on the driver and passenger seat and is supported by two cables.
CAUTION:
Never measure the resistance of the anchor pretensioner directly, the current of the measuring device may cause unexpected airbag deploy.
