TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you replace one or more of the TPMS sensors
or rotate your vehicle's tires, 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 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 inflation pressure indicated on the
tire's sidewall. If using this method to match TPMS
sensors, the complete procedure outlined below must
be performed within 15 minutes of the vehicle being
stationary.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gauge, or a key.
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/wheel positions, the matching
process stops and you will need to start over.The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to Acc.
3. Using the keyless access transmitter, lock and unlock the vehicle's doors.
4. Press the lock and unlock buttons, at the same time, on the keyless access transmitter. The horn
sounds twice, indicating that the TPMS is ready,
and the sensor matching process can begin.
5. Start with the driver side front tire.
6. Remove the valve cap from the valve stem. Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, confirms that
the sensor identification code has been matched to
this tire position.
7. Proceed to the passenger side front tire, and repeat the procedure in Step 6.
8. Proceed to the passenger side rear tire, and repeat the procedure in Step 6.
9. Proceed to the driver side rear tire, and repeat the procedure in Step 6.
