TPMS Sensor Matching Process
Each TPMS sensor has a unique identi cation
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identi cation codes will need to be matched to
the new tire/wheel position. The sensors are
matched, to the tire/wheel positions, in the
following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum in ation
pressure indicated on the tire’s sidewall.
You will have two minutes to match each tire
and wheel position. If it takes longer than
two minutes to match any tire and wheel position,
the matching process stops and you will need
to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle
information button until the TIRE LOCATIONS
PRESS
VTO LEARN message displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate the receiver is ready, and
the TIRE LEARNING ACTIVE message
displays. The TPMS system is ready for the
sensor matching process to begin.
5. Start with the driver side front tire.

Reset the Tire Pressure Monitor System. See
“TPMS Sensor Matching Process” under
Tire Pressure Monitor System on page 391.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Speci cations on page 434.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 404.
When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
