TPM Sensor Identication Codes
Each TPM sensor has a unique identication code. Any
time you rotate your vehicle’s tires or replace one or
more of the TPM sensors, the identication codes
will need to be matched to the new tire/wheel position.
Each tire/wheel position is matched to a sensor, by
increasing or decreasing the tire’s air pressure.
The sensors are matched to the tire/wheel positions in
the following order: left front (LF); right front (RF);
right rear (RR) and left rear (LR).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all four
tire/wheel positions. If it takes longer than one minute,
to match the rst tire and wheel, or more than ve
minutes to match all four tire and wheel positions the
matching process stops and you will need to start over.
The TPM sensor matching process is outlined below:
1. Set the Parking brake.
2. Turn the ignition switch to RUN with the engine off.3. Turn the exterior lamp switch from “Off” to “On” four
times within 3 seconds. A double horn chirp will
sound and the TPM low tire warning light will begin to
ash. The double horn chirp and ashing TPM
warning light indicate that the TPM matching process
has started. The TPM warning light should continue
ashing throughout the matching procedure. The
SERVICE TIRE MONITOR message will be
displayed on the Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPM sensor by increasing or decreasing
the tire’s air pressure for 10 seconds, then stop and
listen for a single horn chirp. The single horn chirp
should sound within 15 seconds, conrming that the
sensor identication code has been matched to this
tire and wheel position. If you do not hear the
conrming single horn chirp, you will need to start
over with step number one. To let air-pressure out of
a tire you can use the pointy end of the valve cap, a
pencil-style air pressure gage or a key.
