Seat Belt TENSIONER

WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

Front seat belt systems incorporate Seat Belt Tensioner (SBT). At the onset of an impact event each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact will be reduced as will the likelihood of contacting interior components. After an impact that deploys the airbag, the seat belt tensioner assembly must be replaced.

The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and stored DTC's if any problem is found.
