Circuit/System Description

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. 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 passenger instrument panel air bag. When the ignition is turned ON, the PPS illuminates the PASSENGER AIR BAG ON/OFF indicators for 5 seconds. The passenger presence module conducts tests on the PPS components and circuits while the PASSENGER AIR BAG ON/OFF indicators are illuminated. If no malfunctions are detected, the passenger presence module will illuminate the PASSENGER AIR BAG indicator ON or OFF, depending on the status of the PPS. If a malfunction is detected, the passenger presence 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 illuminate the AIR BAG indicator to notify the driver of a PPS malfunction.
