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 instrument panel (I/P) module based on the profile classification of the occupant. If the PPS detects a malfunction with the communication circuit then the PPS will set a DTC within the PPS. The SDM will set DTC B0081 indicating a problem within the PPS and will suppress the deployment of the instrument panel (I/P) module and illuminate the AIR BAG indicator.
