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 presence system (PPS) is used to monitor the pressure profile of any occupant that is sitting in the front outboard passenger seat and communicates the profile classification to the sensing and diagnostic module (SDM). The SDM will either enable or suppress the deployment of the passenger frontal airbag module based on the profile classification of the occupant. If the PPS detects the following faults, short to battery, ground or open high resistance it will set DTC 300A, 301A, 303A-303E, 305A-305C or 3003-3059. The PPS will then communicate to the SDM through a dedicated serial data circuit that a PPS fault is present. The SDM will set DTC B0081 indicating a problem within the PPS and suppress the deployment of the passenger frontal airbag module and illuminate the AIR BAG indicator.
