TPM Sensor Identication Codes
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors
or rotate your vehicle’s tires, the identication 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 using a TPMS diagnostic tool. See
your GM dealer for service.
The TPMS 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 TPMS
sensors, the complete procedure outlined below must
be performed within 15 minutes of the vehicle being
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 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 TPMS
is ready, and the sensor matching process
can begin.
5. Start with the driver’s 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 ve seconds, or until a horn
chirp sounds. The horn chirp, which may take up to
30 seconds to sound, conrms that the sensor
identication 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 passenger’s side front tire, and
repeat the procedure in Step 6.
5-68

8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and repeat the
procedure in Step 6.
10. After hearing the conrming single horn chirp for the
driver’s side rear tire, a double horn chirp will sound
to signal the tire matching mode is no longer active.
Press the push-button ignition switch to ACC.
11. Set all four tires to the recommended air pressure
level as indicated on the tire and loading
information label.
12. Put the valve caps back on the valve stems.
The spare tire does not have a TPMS sensor. If you
replace one of the road tires with the spare, the
SERVICE TIRE MONITOR message will be displayed
on the DIC screen. This message should go off
once you re-install the road tire containing the TPM
sensor. The SERVICE TIRE MONITOR message is also
displayed when the TPMS system is malfunctioning.
One or more missing or inoperable TPMS sensors will
cause the SERVICE TIRE MONITOR message to
be displayed. See your GM dealer for service.Federal Communications Commission
