DESCRIPTION
The Seat Belt Buckle Pretensioners (BUPT) are installed in the right side of the driver seat and the left side of the
passenger seat. When a vehicle crashes with a certain degree of frontal impact, the seat belt buckle pretensioner
helps to reduce the severity of injury to the front seat occupants by retracting the seat belt buckle. 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 Buckle Pretensioner (BUPT) 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.

Brake Chatter Brake chatter is usually caused by loose or worn components, or
glazed or burnt linings. Rotors with hard spots can also contribute to
brake chatter. Additional causes of chatter are out - of- tolerance rotors,
brake lining not securely attached to the shoes, loose wheel bearings
and contaminated brake lining.
