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. This prevents the front occupants from thrusting forward and hitting the steering wheel or the instrument panel when the vehicle crashes.
   
•
Never attempt to measure the circuit resistance of the Seat Belt Pretensioner (BPT) even if you are using a specified tester. If the circuit resistance is measured with a tester, the pretensioner will be ignited accidentally. This will result in serious personal injury.
