Hyundai Tucson: Seat Belt Pretensioner
Description
The Seat Belt Pretensioners (BPT) are installed inside Center Pillar (LH & RH). When a vehicle crashes with a certain degree of frontal impact, the pretensioner seat belt helps to reduce the severity of injury to the front seat occupants by retracting the seat belt webbing. (Seat belt pretensioner may be activated in side impact collisions if the vehicle has side airbag or curtuain airbag.) This prevents the front occupants from thrusting forward and hitting the steering wheel or the instrument panel when the vehicle crashes.
WARNING
Never attempt to measure the circuit resistance of the Seat Belt Pretensioner (BPT) even if you are using the specified tester. If the circuit resistance is measured with a tester, the pretensioner will be ignited accidentally. This will result in serious personal injury.
