It's great to just have a tool to read/troubleshoot the TPMS system and be able to read the codes/information on the ODB-II bus. And it can be used for any vehicle due to the large installed vehicle database. TPMS ranges from simply reading a wheel to comparing 4 (5 if you have a spare) wheels to full diagnostics and troubleshooting, relearning and actually changing the ID number. TPM. I highly recommend this tool even for a weekend mechanic. Now you can help your friends.
