Circuit/System Description

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

The PASSENGER AIR BAG ON/OFF indicators are used to notify the driver when the passenger presence system (PPS) has enabled or disabled the instrument panel (I/P) inflator module. When the ignition is turned ON, the PPS module is supplied with voltage and illuminates both PASSENGER AIR BAG ON/OFF indicators for 5 seconds; then the PPS module conducts tests on the PPS components and circuits while both PASSENGER AIR BAG ON/OFF indicators are illuminated. If no malfunctions are detected, the PPS module will illuminate either the ON or OFF indicator of the PASSENGER AIR BAG indicator, depending on the status of the PPS. If a malfunction is detected, the PPS module will store a diagnostic trouble code (DTC), default the PPS to the OFF state, and communicate with the SDM that a DTC has been set. The SDM will request the instrument panel cluster (IPC) to illuminate the AIR BAG indicator to notify the driver of a PPS malfunction.
