- A TPMS activation tool – This tool sends the signal to perform the “wake up” function in a relearn process. A quality TPMS activation tool will feature a digital display to show a sensor’s ID number, pressure and temperature information, as well as battery state.
- A scan tool/diagnostic tool – While some TPMS tools have these functions built in, others don’t. Depending on the vehicle make, a scan tool/diagnostic tool will allow the technician to read and clear codes, as well as read and write sensor IDs. Certain vehicles manufactured after 2009 or 2010 have datastream and additional test functions that a scan tool can read. A very few TPMS tools have the ability to do more than read and clear or read and write.
- A reliable information source – This may be the most important component to a successful TPMS job. A quality information source is needed to inform the tech on:
-- How the vehicle’s TPMS works.
-- How the relearn process works.
-- The read and write process.
-- Whether or not a drive is required.
-- Whether or not there is a reset switch or button.
