I have a 2009 Nissan Xterra that has TPMS issues from time to time. The dealer did not find anything in the system. I was tired of going to the dealer for a reset so I decided to invest $10 and buy this tool. After receiving it and reading the instructions, I moved the tool to the valve stems as instructed. TPMS has reset itself. It seems too easy to work with, but it is.
