TPM Sensor Identi cation Codes
Each TPM sensor has a unique identi cation code. Any
time you replace one or more of the TPM sensors or
rotate your 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: left front (LF), right front (RF), right
rear (RR), and left rear (LR) using a TPM diagnostic
tool. See your GM dealer for service.
The TPM sensors may also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. If using this method to match TPM
sensors, the complete procedure outlined below must
be performed after the vehicle has been driven at
least 20 mph (32 km/h), for at least 10 seconds, and
within 15 minutes from when the vehicle is stationary.
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/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 OFF/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. A single
horn chirp will sound, indicating that the TPM
system is ready, and the sensor matching process
can begin.
5. Start with the left (driver’s side) front tire.
6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, con rms that the
sensor identi cation code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a pencil-style
air pressure gauge, or a key.
7. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 6.
8. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 6.
9. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 6.
10. After hearing the con rming double horn chirp, for
the left rear tire, exit the matching process by
pressing the push-button ignition switch to
OFF/ACC.
