The passenger presence system has received a fault signal from the sensor mat.



Action Taken When the DTC Sets



The SDM requests the instrument panel cluster to illuminate the AIR BAG indicator.



Conditions for Clearing the DTC



* The condition for setting the DTC no longer exists.



* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.



Diagnostic Aids



* If either the SDM or PPS were replaced verify that the correct part numbers were used for the vehicle application.



* If this DTC is set as either current or history it may have been caused by an electronic device. If an electronic device (Computers, MP3



Players, Cell Phones, Diagnostic Scan Tool, etc.) was placed on the passenger seat the passenger presence module may command the



passenger air bag indicator to turn on and/or command the passenger seat belt indicator to turn on. Make sure there are no objects on the



passenger seat and clear the DTCs. If this DTC resets then perform this diagnostic. If the DTC does not reset there is no further work needed



on the passenger presence system.

Circuit/System Testing



Note: This system is serviced as a kit (seat foam, module, and/or sensing mat). Perform a Passenger Presence System Preload procedure whenever



a component is replaced. Inspect the following component connectors for damage or corrosion. Repair or replace the affected



component/connector:



1. Confirm that all passenger presence system connectors are fully seated.



2. Verify DTC B0074 is not set.



瀚慖f the DTC is set, replace the K85 passenger presence system sensor mat.



Repair Instructions



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
