Circuit Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The seat heater mat which is a part of the heated seat system is calibrated as a part of the inflatable restraint Passenger Presence System (PPS). If the vehicle is equipped with a front passenger seat heater, the PPS continuously monitors for faults from the heated seat element. If the PPS determines there is a fault in the heated seat element supply circuit, the PPS will set DTC 052, turn the passenger air bag status indicator to OFF, and notify the sensing and diagnostic module (SDM) of a fault in the PPS through a non class 2 communications circuit. The SDM will then turn the air bag indicator to ON, and set DTC B0092 indicating a problem within the PPS and will suppress the deployment of the instrument panel (I/P) module. The heater seat mat along with the PPS is a calibrated system and must be replaced as a complete unit
