Front Seat Belt Pretensioners

WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Refer to SIR Caution .

The seat belt pretensioners, with load limiter for some vehicles, are assembled with each front seat belt retractor to retract the seat belt webbing when accounted frontal collision. The seat belt pretensioners are controlled by the sensing and diagnostic module (SDM). The seat belt pretensioner contains an igniter charge and a gas generator to pull the seat belt webbing. The seat belt pretensioner must be replaced after an accident that causes its activation.

The seat belt pretensioner also contains a shorting bar to prevent current from travelling through the seat belt pretensioner during servicing. The shorting bar is disengaged when the connector is connected.
