Kia Soul EV (PS EV) 2015-2020 Service Manual / Restraint / Seat Belt Pretensioner / Emergency Fastening Device (EFD) Description and Operation

Description
Emergency Fastening Device (EFD) is deployed concurrently with the Belt Pretensioner to strongly pull down the seat belt during a deployment condition after a collision. It is located near the anchor on driver and passenger seats to make up for the existing short stroke. EFD is an auxiliary equipment that gives extra protection to the driver and passenger from breaking away and leaning toward the anchor side during a collision by preventing the seat belts from getting loose.
   
Never measure resistance of EFD directly as the electric current from measuring device may cause unexpected deployment of airbag.
