Passenger Presence System Rezeroing
Introduction
The Inflatable Restraints Passenger Presence System
(PPS) is a calibrated system that requires rezeroing
anytime the seat cushion trim attachments have been
removed or the PPS has been replaced. The procedures
below are designed to assist in the rezeroing of the PPS.
Before you start, read these procedures carefully and
completely. For further information regarding the PPS
refer to "SIR System Description and Operation".
NOTE
The following procedures must be followed:
1. Read this procedure carefully and completely.
2. The PPS will not function properly if the PPS
rezeroing procedure is not performed.
3. Perform the "Diagnostic System Check - Vehicle
Diagnostic Information: " after successfully
completing the rezeroing procedure to ensure the
system is functioning properly.
Passenger Presence System (PPS) Rezeroing
Procedure
NOTE
Before rezeroing the PPS, 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.
NOTE
When rezeroing the PPS, the instrument
panel cluster (IPC), and Passenger Air Bag
ON/OFF indicator will begin dimming ON and
OFF. This is normal operation during the
rezeroing procedure and does not indicate
additional system faults.
1. Empty the front outboard passenger seat.
2. Verify that all SIR and PPS components, connectors,
and connector position assurances (CPAs) are
properly connected and mounted.
3. Install a scan tool.
4. Turn ON the ignition, with the engine OFF.
NOTE
All SIR and PPS DTCs must be cleared before
rezeroing the PPS. The presence of current
or history DTCs will prevent the PPS from
rezeroing and may set additional DTCs.
