Passenger Presence System Displaying Code Procedure (Base): 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.

When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) will establish communication with the passenger presence system (PPS). When communication is established, the SDM will first request traceability/verification information from the PPS. If the SDM confirms that the correct PPS is in the vehicle, then the SDM will request the PPS status Data. If the PPS detects a malfunction, the PPS will set a DTC, and communicate with the SDM that a malfunction has occurred. The SDM will respond by disabling the instrument panel (I/P) module deployment loop, and then sets DTC B0081 while commanding the AIR BAG indicator ON to notify the driver of a PPS malfunction. The DTCs that the PPS set are non-class 2 and have to be retrieved through the SDM. The procedures below are designed to assist in the retrieval 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 .
