Circuit/System Description

WARNING: This page is about a different car, the 2015 GMC Acadia, 2015 Chevrolet Traverse, and 2015 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 ignition voltage is supplied to the passenger air bag ON/OFF indicators and to the PPS. 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 supplemental inflatable restraints system to turn ON the indicators as necessary.

After the SDM is programmed, the SDM setup procedure is required. During this set up procedure, the SDM will compare the content that was just programmed to the actual components that are installed on the vehicle. If the SDM detects that there are too few or too many components on the system, DTC B1019 00 will set and not allow the setup procedure to complete.
