Circuit/System Description

The passenger air bag ON/OFF indicators are used to notify the driver when the passenger presence system has enabled or disabled the Passenger Instrument Panel Air Bag. When the ignition is turned ON, the ignition voltage is supplied to the Passenger Presence Module. When the Inflatable Restraint Sensing and Diagnostic Module (SDM) receives the appropriate serial data message from the Passenger Presence Module, the Inflatable Restraint Sensing and Diagnostic Module will then provide voltage to the appropriate indicator.
