TTPMS must learn the location of the
installed tire sensors to show correct air
pressure and temperature for each tire. To
set up, use one of the following options or
see a tire or trailer dealer for service. The
learning process must be repeated when the
trailer tires are rotated or replaced.
Tool Method: A TTPMS activation tool can
be purchased separately to learn the sensor
locations.
Manual Method: Without the tool, the air
pressure can be increased or decreased in
each tire for 10 seconds. Do not exceed the
maximum inflation pressure found on the
tire sidewalls. Make sure to readjust tire
pressure to the recommended level when
the process is complete.
Sensor Learning Steps
To complete the sensor-to-vehicle learn
process:
1. Touch Start on the Learn Sensors screen.
The horn chirps twice and the Learning
Active screen appears on the
infotainment screen.
2. Start with the driver side front
trailer tire.
3. Activate the tool near the valve stem or
adjust the air pressure of this tire until
the horn chirps and all working vehicle
and trailer lights flash.
The process stops without saving the
sensor locations if this step takes more
than two minutes.
4. Move to the next tire and repeat Step 3
for each sensor. The horn chirps twice
when all sensors are completed.
5. Return to the vehicle to complete the
setup.
