SAFETY 183
The TTPMS consist of the following components:
• Trailer Receiver Module
• Trailer Interface Module
• Two to twelve tire pressure monitoring sensors depending
on trailer configuration
The TTPMS is configured though the trailer settings menu in the
Uconnect system by selecting the desired trailer number (up to
four trailers can be configured), the number of axles (1 - 3), the
number of trailer tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. Refer to “Uconnect Settings” in “Multimedia” for
further information.
Tire Pressure Monitoring Low Pressure Warnings
When a tire pressure low in one or more of the active road
tires is detected a chime will sound. In addition, the instru-
ment cluster will display a graphic showing the pressure
values of each tire with the low tire pressure values in a
different color. An “Inflate to XXX” message will also be
displayed.
NOTE:
"XXX" = TPM trailer tire target pressure value programmed
by the customer
Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a
different color in the instrument cluster graphic) to the
customer programmed target tire pressure value as shown in
the “Inflate to XXX” message. Once the system receives the
updated tire pressures, the system will automatically update
the graphic display in the instrument cluster will return to
it’s original color. The vehicle may need to be driven for up
to 10 minutes above 15 mph (24 km/h) in order for the
TTPMS to receive the updated information.
Service TTPMS Warning
If a system fault is detected, the system fault will sound a
chime and the instrument cluster will display a “Trailer Tire
Pressure System Service Required” 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.
Once the system fault is corrected the "Trailer Tire Pressure
System Service Required" message will no longer be
displayed and the dashes will be replaced by pressure
values. The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order for the TTPMS
to receive the updated information.
