Circuit / System Description
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 seat belt pretensioner during servicing. During a frontal crash of sufficient force, the sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the seat belt pretensioner. The 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.
