Passenger Presence System Flash Code Procedures: Introduction

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.

When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within itself. When the SDM has completed the power-up mode the SDM will establish communication with the Passenger Presence System (PPS). The PPS will respond by performing diagnostic tests to check for proper circuit continuity and for shorts to ground and voltage within the PPS. If the PPS detects a malfunction, the PPS will set a DTC, then communicate through a non class 2 communications circuit to the SDM that a malfunction has occurred, while turning the passenger air bag status indicator to OFF. The SDM will respond by disabling the instrument panel (I/P) module deployment loop, setting either DTC B0092 or DTC B0098 and commanding the AIR BAG indicator ON. The SDM notify the driver of a PPS or SIR malfunction by turning ON the AIR BAG indicator on the cluster. The DTCs that the PPS set are non class 2 and have to be flashed through the PASSENGER AIR BAG ON/OFF indicators. The procedures below are designed to assist in the flashing of these codes. Before you start, read these procedures carefully and completely. For further information regarding the PPS refer to SIR System Description and Operation .
