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.
If the pairing process times out after three
minutes of no communication with a sensor, a
double horn chip will occur indicating the
pairing has failed and a message will display on
the radio indicating the process was
unsuccessful. Under certain circumstances, the
double horn chirp may continue to happen
every three minutes indicating the failed
pairing. If this happens, the horn chirping may
be canceled by cycling the ignition button OFF
and then back to the run position.
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 instrument 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.
Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
message will be displayed in the Instrument
Cluster when a trailer number is selected that
does not have configuration values entered for
the (Number of Tires, Number of Axles, SET
Target Tire Pressure, trailer TPM sensor ID's).
To correct this condition the (Number of Tires,
Number of Axles, and SET Target Tire Pressure)
values must be entered in the radio for the trailer
number selected. The trailer sensors must also be
paired to the trailer. Refer to the “Uconnect
Settings” in “Multimedia” for further information.
