2017 CHRYSLER PACIFICA sensor

The TPMS consists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID).
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the EVIC/DID will
display an Inflate to XX message and a graphic showing
the pressure values of each tire with the low tire pressure
values in a different color. Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a
different color in the EVIC/DID graphic) to the vehicle’s
recommended cold placard pressure value as shown in
the
Inflate to XX message. Once the system receives the
updated tire pressures, the system will automaticallyTire Pressure Monitoring System

update, the pressure values in the graphic display in the
EVIC/DID will return to their original color, and the
“Tire Pressure Monitoring Telltale Light” will turn off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. In addition, the EVIC/DID will
display aSERVICE SYSTEM message for a minimum of
five seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition is cycled, this sequence will repeat, pro-
viding the system fault still exists. If the system fault no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “SERVICE SYSTEM
message will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur
due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
300 SAFETY

Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressuremonitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition cycle, the “TPMS
Telltale Light” will remain on and a chime will sound.
In addition, the graphic in the EVIC/DID will still
display a different color pressure value and an Inflate
to XX message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid. In addition, the EVIC/DID will display a “SER-
VICE SYSTEM” message for five seconds and then
display dashes (- -) in place of the pressure value. 4. For each subsequent ignition cycle, a chime will
sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
EVIC/DID will display a “SERVICE SYSTEM” mes-
sage for five seconds and then display dashes (- -) in
place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPMS Telltale Light” will turn off and the graphic in
the EVIC/DID will display a new pressure value
instead of dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of the
four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.

locking mode.
WARNING!
•The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is
only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.

322 SAFETY

WARNING!
•Being too close to the steering wheel or instrument
panel during Advanced Front Air Bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfortably
extending your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced Front
Air Bag can cause death or serious injury to a child
12 years or younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides output appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.

vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.
Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Ad-
vanced Front Air Bag output appropriate to the occu-
pant’s seated weight, as determined by the OCS.
The Occupant Classification System (OCS) consists of the
following:
•
Occupant Restraint Controller (ORC)
5
SAFETY 325

•Occupant Classification Module (OCM) and Sensor
located in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) and Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is lo-
cated beneath the passenger seat cushion foam. Any
weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front pas-
senger ’s most probable classification. The OCM commu-
nicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and prop-
erly wearing the seat belt. The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag if
the OCS estimates that:
•
The front passenger seat is unoccupied or has very
light objects on it; or
• The front passenger seat is occupied by a small pas-
senger, including a child; or
• The front passenger seat is occupied by a rear-facing
child restraint; or
• The front passenger is not properly seated or his or her
weight is taken off of the seat for a period of time.
