TPMS Sensor Identification Codes
Each TPMS sensor has a unique identification code.
Any time you rotate your vehicle’s tires, install the spare
tire onto your vehicle, or replace one or more of the
TPMS sensors, the identification 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’s side front tire, passenger’s side front
tire, passenger’s side rear tire, and driver’s side rear tire.
You will have one minute to match the first tire/wheel
position, and five minutes overall to match all
four tire/wheel positions. If it takes longer than
one minute, to match the first tire and wheel, or more
than five minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.
The TPMS sensor matching procedure is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the engine off.
3. Turn the exterior lamp switch from AUTO to ON
four times within three seconds. A double horn
chirp will sound and the TPMS low tire warning
light will begin to flash. The double horn chirp
and flashing TPMS warning light indicates
the TPM matching process has started.
The TPMS warning light should continue flashing
throughout the matching procedure. The SERV TPM
message will be displayed on the Driver Information
Center (DIC).
4. Start with the driver’s side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS 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, confirming that the sensor identification
code has been matched to this tire and wheel
position. If you do not hear the confirming 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 pointed end of the valve cap, a pencil-style
air pressure gage, or a key.
6. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 5.
8. Proceed to the driver’s side rear tire, and repeat
the procedure in Step 5.
