B0081 CHEVROLET Description

When the ignition is turned ON, the Passenger Presence System (PPS) and 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 PPS. The PPS will respond by commanding both of the PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds. The SDM will then transmit a request message to the PPS to receive the PPS verification ID. The PPS will transmit the verification ID to the SDM, and the SDM will compare the ID received to data stored in memory. If the data stored in memory does not match the information transmitted by the PPS or the SDM has detects that the PPS has set a current Diagnostic Trouble Code (DTC), the SDM will then disable the Instrument Panel (I/P) module deployment loop, set DTC B0081, and command the AIR BAG indicator ON.
