Trailer Tire Pressure Monitoring
Operation
If equipped, the Trailer Tire Pressure
Monitoring System (TTPMS) is
designed to monitor the pressure of
the trailer tires and warn the driver
when a low pressure condition exists.
TTPMS sensors for four tires are
provided. The system can
accommodate a trailer with up to six
tires if additional sensors are
purchased from the dealer. Also, the
system can be paired with up to five
individual trailers.
Prior to use, the vehicle must learn
the sensors by following the learning
process. See
Contact your trailer service center or
tire service center to have the
pressure sensors installed inside the
trailer tires. The technician should
insert the sensor stem through the
hole in the trailer wheel. When the
sensor is correctly positioned, the nut
on the sensor stem should be
tightened to 8
Y
(6 lb ft). When
mounting the trailer tire onto the
trailer wheel be careful not to damage
the sensor.
The Trailering App can be used to
view the tire pressures after the
recommended trailer tire pressures
have been entered. Refer to the trailer
tire placard on the trailer or the trailer
tire sidewall for the recommended tire
pressure.
The system is compatible with trailer
tires that have placard pressure values
from 103 - 689 kpa (15 - 100 psi). The
hole in the wheel for the tire stem
must be 11.43 mm (0.453 in) in
diameter. Use of the pressure sensors
on a wheel with a different stem hole
size could result in loss of air from
the tire.
If a low trailer tire pressure condition
is detected, the TTPMS displays a
warning message on the DIC. If the
warning message is displayed, stop as
soon as possible and inflate the tires
to the recommended pressure shown
on the tire placard on the trailer.
In addition, the TTPMS monitors the
temperature of the trailer tires. If the
system detects a high temperature on
one or more of the trailer tires, a
warning message will be displayed on
the DIC. If this warning message is
displayed, stop as soon as possible,
and inspect the overheated trailer tire.
