Circuit/System Description

WARNING: This page is about a different car, the 2011 Cadillac DTS. 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 ignition voltage is supplied to the passenger air bag ON/OFF indicators and to the passenger presence module. The instrument panel cluster (IPC) grounds all indicator control circuits to the passenger air bag ON/OFF indicators for illumination. The IPC receives serial data messages from the SDM to illuminate the indicators as necessary.
