Passenger Presence System Preload Test: Notes

WARNING: This page is about a different car, the 2011 GMC Acadia, 2011 Chevrolet Traverse, and 2011 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The passenger presence system consists of an electronic control module, a conductive based sensor mat, wiring harness, and PASSENGER AIR BAG ON/OFF indicators. The sensor mat is made up of several flexible conductive metal strips placed underneath the seat cushion trim. These sensor strips transmit and receive a low level electric field. The weight of the occupant sitting in the front passenger seat is measured as a change in current flow within the sensor mat. If the passenger seat bottom cushion, seat bottom trim, or heater pad has been serviced, reinstalled, or removed for any reason, the procedure below will check for any preloads on the passenger presence system. A service replacement passenger presence module does not require an unlock procedure prior to an initial preload test.
