TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle s tires or replacing one or
more of the TPMS sensors.
Also, the TPMS sensor matching
process should be performed after
replacing a spare tire with a road
tire containing the TPMS sensor.
The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Press and on the
Remote Keyless Entry (RKE)
transmitter at the same time for
approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and TIRE LEARNING ACTIVE
message displays on the DIC
screen.
4. Start with the driver side
front tire.
5. Place the relearn tool against
the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.

6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5. The horn sounds
two times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition to LOCK/OFF.

recommended air pressure
level as indicated on the Tire
and Loading Information label.
