Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The passenger side deployment loop consists of an inflatable restraint side impact module-RF, the inflatable restraint side impact module wiring harness, and the side impact module-RF high and low circuits. A shorting bar is used within the side impact module-RF connector to short together both the side impact module-RF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) will allow current to flow through the deployment loop in order to deploy the side impact module-RF. 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 Diagnostic Trouble Code (DTC) will be stored in memory.
