Passenger Presence System Programming and Setup
WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Before the passenger presence system (PPS) can be checked for zeroed, the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When the preload test is perform, the instrument panel cluster (IPC) and dash lights may begin illuminating at varying intensity. This is normal operation during the preload test procedure and does not indicate a system fault.
If the PPS is replaced or serviced, the passenger presence system rezeroing procedure must be performed. Refer to Passenger Presence System Rezeroing .
