Chrysler Pacifica. Manual - part 476

driver seat belt is unbuckled, and the vehicle’s speed
is greater than 5 mph (8 km/h) in a forward gear, the
Enhanced Fasten Seat Belt Reminder will activate.
This will cause the Seat Belt Lamp to blink and a
slow continuous chime to sound for 5 seconds. After 5
seconds, the chime will stop, but the lamp will
remain illuminated for an additional 3 seconds. The
Enhanced Seat Belt Reminder cycles for a total of 12
times (96 seconds). After the 12th time, the Seat Belt
Lamp will remain on without any chime. Buckling
the driver seat belt at anytime will cancel the Fasten
Seat Belt Reminder announcement.

CHECK ENGINE LAMP

The cluster will sound a single chime after illumi-

nating the indicator.

ENGINE TEMPERATURE LAMP

The cluster will sound a single chime when the

indicator first illuminates at 252°F (122°C).

TRACTION CONTROL LAMP

The cluster will sound a chime, illuminate a red

priority indicator lamp, and display an EVIC warn-
ing message after illuminating the indicator if the
traction control system:

• is active.

• is suspended.

• needs service.

• is disabled by the driver.

TURN SIGNAL ON

If the BCM detects a turn signal input continu-

ously for 1.0 mile (0.6 km) and the vehicle speed is
greater than 15 mph (24 km/h), the cluster will
chime continuously, illuminate an amber message
indicator lamp, and display an EVIC warning mes-
sage, until the turn signal is cancelled.

OTHER CHIME ON CONDITIONS

BULB CHECK

The chime will sound one time during bulb check.

BRAKE LAMP

The cluster will sound a chime, illuminate a red

brake lamp, and display an EVIC warning message if
the:

• Park brake is engaged and the vehicle speed

exceeds 1 mph (1.61 km/h).

• Brake fluid is low.

MEMORY

The cluster will sound a chime and display an

EVIC message when:

• Memory position #1 is set.

• Memory position #2 is set.

• The vehicle is out of park and a memory recall is

selected.

• A memory recall is activated while the seat is in

motion during another memory recall.

SERVICE

The cluster will sound a chime, illuminate an

amber message indicator lamp, and display an EVIC
message when the vehicle reaches the time to per-
form service.

REMOTE KEYLESS ENTRY

The cluster will sound a chime and display an

EVIC message upon activation of:

• The key fob with a low battery.

• An invalid key fob and key.

SERVICE IMMOBILIZER

The cluster will sound a chime and display an

EVIC message when there is a problem with the
SKREEM Module.

POWER LIFTGATE

The cluster will sound a chime and display an

EVIC message when there is a power liftgate actua-
tion with the:

• Overhead console or RKE and the doors are

locked.

• Overhead console and the vehicle is not in park.

• Overhead console or RKE and the temperature

is too cold for actuation.

• Overhead console or RKE and the temperature

is too hot for actuation.

TIRE PRESSURE MONITOR SYSTEM

The tire pressure monitoring system will request:
• A chime, illuminate an amber TPM lamp, and

display an EVIC message when the system senses
that there is a low tire pressure problem.

• Three fast chimes, illuminate an amber TPM

lamp, and display an EVIC message when the sys-
tem senses that one of the four original tires on the
vehicle has been changed.

• A chime, illuminate an amber TPM lamp, and

display an EVIC message if the system does not
sense any tire pressure.

• A chime, illuminate an amber TPM lamp, and

display an EVIC message when the tire system needs
service.

PARK ASSIST SYSTEM

The Park Assist System display activates an audi-

ble tone that changes from intermittent to continu-
ous as the final two Light Emitting Diodes (LED’s)
are illuminated on one side or both sides of the dis-
play.

CHIME/BUZZER

8B - 3

CHIME/BUZZER (Continued)

The system detection length from the rear of the

vehicle is 0.3 meters to 1.5 meters. This area extends
around the rear side of the vehicle. The system detec-
tion height from the ground is 0.2 meters to about
1.5 meters. The radio mutes when the system acti-
vates its audible tone.

When the driver selects Reverse, the system scans

for objects behind the vehicle using four sensors
located in the rear bumper. A warning display above
the rear window provides both visible and audible
warnings indicating the range of the object.

The system is active only when the transmission

gear selector is in reverse for vehicle speeds less than
16 Km/h (10 mph). If the vehicle’s Parking/Emer-
gency Brake is applied, the system is deactivated.

The display contains two sets of yellow and red

Light Emitting Diode’s (LED’s) that the driver can
see as they look over their shoulder while backing
up. Each side of the vehicle has its own warning
LED’s. The system provides a visual warning by illu-
minating one or more yellow LED’s as the vehicle
gets closer to the object. As the vehicle continues to
approach the object, one red LED is illuminated and
the system emits a series of short beeps. The tone
will remain constant and both red LED’s are illumi-
nated once the vehicle is within 12 inches (30.5 cm)
of the object.

The system can be turned ON or OFF through the

Electronic Vehicle Information Center (EVIC) when
the vehicle is in PARK. If the park assist system is
turned OFF, a single chime will sound and the EVIC
will display the following message “REAR PARK
ASSIST OFF”, when the vehicle is in reverse.

• Ensure that the rear bumper is free of dirt and

debris to keep the system operating properly.

• Jackhammers, large trucks, and other vibrations

could affect the performance of the system.

• Ensure that the parking brake is not applied.
If “Service Park Assist System” appears in the

EVIC after making sure the rear bumper is clean,
proceed to diagnose the system using a scan tool and
the appropriate diagnostic information.

PARK ASSIST DISPLAY

DESCRIPTION

The Park Assist Display (Fig. 1) is a molded plastic

unit housing Light Emitting Diodes (LED’s) and a
chime module. Located in the rear of the vehicle for
easy visual reference when the driver is backing up.

The display is used to alert the driver of any obsta-

cles detected in the rear of the vehicle (Fig. 2). The

chime or audible signal also comes from the display
unit.

The Park Assist Display is located in the rear of

vehicle, over the rear window in the headliner (Fig.
2).

OPERATION

When the ignition is put in the RUN position, all

the Light Emitting Diodes (LED’s) will illuminate for
approximately one second. This will be interrupted if
the system senses an obstacle.

The ready status will be sensed by the outermost

two yellow LED’s being illuminated at 50% intensity.
As the obstacle is sensed, the yellow LED’s will start
illuminating inward until the object in approximately
40 cm (16 in.) away and then the inner red LED will
light.

The display is sensitive to which side of the rear of

the vehicle that the object is detected. If on the left
rear, the left segments will light and the same for the
right side of the vehicle.

one electrical connector. There are two mounting tabs
that affix the module to the left inner quarter panel
with two screws.

The module has a number of functions:
• Supply voltage to the sensors and display.

• Disconnection of the display with bus idle and

over voltage Vmax.

• Triggering the sensors.

• Analyze echo delay times and calculate obstacle

distances.

• Bi-directional data communication to the display

for diagnosis.

• System diagnostics - diagnosis and error han-

dling (sensors, display, module).

• Data exchange over the Programmable Commu-

nication Interface (PCI) data bus.
