Circuit/System Description

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

The PASSENGER AIR BAG ON/OFF indicators, located in the center of instrument panel cluster (IPC), are used to notify the driver when the Passenger Presence System (PPS) has enabled or disabled the I/P inflator module. When the ignition is turned ON, the PPS module is supplied with voltage and commands the PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds. The PPS module conducts tests on the PPS components and circuits while the PASSENGER AIR BAG ON/OFF indicators are ON. If no malfunctions are detected, the PPS module will turn the PASSENGER AIR BAG indicator ON or OFF, 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 IPC to turn the AIR BAG indicator ON to notify the driver of a PPS malfunction.
