Seat Belts: Notes

The seatbelt tensioners have the task of removing or reducing any belt slack in the pelvic and shoulder region. The seatbelt tensioner forms a unit with the seatbelt buckle. The belt buckle switch, a two-wire Hall switch, is monitored by the airbag control unit. In the event of a fault, a fault code memory entry is made in the airbag control unit.
