Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
The seat belt pretensioner deployment loop consists of a seat belt pretensioner, the seat belt pretensioner - high and seat belt pretensioner - low circuits. A shorting bar is used in the seat belt pretensioner connector which will short together the seat belt pretensioner - high and seat belt pretensioner - low circuits when the connector is disconnected, this will help to prevent unwanted deployment of the pretensioner during servicing. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored.
