Select the ACC position on the ignition switch by pushing the bottom of the rocker switch. You will have a yellow light illuminated under the ACC on the ignition/start switch.
Simultaneously press the lock and unlock buttons on your fob until a horn chirp sounds, indicating the TPM learn mode has been enabled.
Push the bottom of your ignition switch to select the OFF position of the ignition to exit the TPMS learn mode.
This info is directly from the directions that came with my KTI tool.
