Passenger Presence System Flash Code Procedures: Introduction

WARNING: This page is about a different car, the 2010 Saturn Sky and 2010 Pontiac Solstice. 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 module will respond by performing diagnostic tests to check for proper circuit continuity and for shorts to ground and voltage within the PPS module. If the PPS module detects a malfunction, the PPS module will set a DTC, then communicate through a non class 2 or GMLAN 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 passenger instrument panel air bag deployment loop, setting DTC B0081, B0092 or 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 instrument panel cluster. The DTCs that the PPS module set are non class 2 or GMLAN 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 PPS refer to SIR System Description and Operation .
