The TPMS sensor matching process for 08 TrailBlazer LT is outlined below:
Set the parking brake.
Turn the ignition switch to ON/RUN with the engine off.
Turn the headlamp control from off to parking lamps 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 indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure.
Start with the driver side front tire.
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.
Proceed to the passenger side front tire, and repeat the procedure in Step 5.
Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
Proceed to the driver side rear tire, and repeat the procedure in Step 5.
After hearing the confirming horn chirp for the driver's side rear tire, check to see if the TPMS warning light is still flashing. If yes, turn the ignition switch to LOCK/OFF to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
Set all four tires to the recommended air pressure level
