Passenger Presence System Flash Code Procedures: Introduction

WARNING: This page is about a different car, the 2010 Chevrolet Malibu. 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) enters the power-up mode and performs self tests of critical internal functions. After completing the power-up mode, the SDM establishes communication with the Passenger Presence System (PPS) module. The PPS module responds by performing diagnostic tests for proper circuit continuity and shorts to ground and voltage within the PPS. If the PPS module detects a malfunction, a DTC will set and the module communicates to the SDM that a malfunction has occurred, while turning the passenger air bag status indicator to OFF. The SDM responds by disabling the instrument panel (I/P) module deployment loop, setting DTC B0081 and commanding the AIR BAG indicator ON. The SDM notifies the driver of a PPS or SIR malfunction by turning ON the AIR BAG indicator. The DTCs that the PPS sets are non 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 the PPS refer to SIR System Description and Operation .
