GMC YUKON DENALI 2004 Owners Manual TPM Sensor Identi®cation Codes
Each TPM sensor has a unique identi®cation code.
Any time you rotate your vehicles tires or replace one
or more of the TPM sensors, the identi®cation codes will

TPM Sensor Identi®cation Codes
Each TPM sensor has a unique identi®cation code.
Any time you rotate your vehicle's tires or replace one
or more of the TPM sensors, the identi®cation 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 ªOffº to ªOnº
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, con®rming that the sensor identi®cation
code has been matched to this tire and wheel
position. If you do not hear the con®rming 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.
6. Proceed to the right (passenger's side) front tire,
and repeat the procedure in step 5.
7. Proceed to the right (passenger's side) rear tire,
and repeat the procedure in step 5.
8. Proceed to the left (driver's side) rear tire, and
repeat the procedure in step 5.
