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. |
