Hummer H3 H3T TPMS Reset Procedure

GM-6

1. Apply parking brake. Turn ignition to ON position (engine off)
2. Turn headlight switch from OFF to parking lamps 4 times within 4 seconds. A double horn chirp will sound and the TPMS telltale will begin blinking to indicate the learn mode is enabled.
3. Starting at the LF tire increase/decrease pressure until horn sounds.
4. After horn sounds, proceed as in step 3 for the next 3 sensors in the following order : RF, RR LR.
5. After LR sensor has been learned, turn ignition to OFF position. Adjust all tires to pressure listed on tire placard. *If headlight switch does not enable TPMS Learn Mode, use TPMS Learn button on dash.

This seems so so confusing.

Does anyone know of a phone number I can call who can assist me with procedure while I carry it out?
