Circuit / System Description
The inflatable restraint instrument panel (I/P) module deployment loop consists of an inflatable restraint I/P module, the I/P module high and I/P module low circuits. A shorting bar is used in the inflatable restraint I/P module connector, which will short together the I/P high and I/P module low circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module 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 inflatable restraint I/P module. 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.
