Hi All,

Recently swapped over the winters to the GX. Had them on last year. Winters and wheels as well as TPWS sensors in the winters are from the dealer and as mentioned, worked last year. Summers worked all good. I swapped over myself and hit the change wheel set toggle in the vehicle settings. It seems to be detecting the wheels above my truck (where I store the summers) but when I drive off those values disappear and it does it over and over again because I only do a lot of short trips and believe it needs a good 30 mins of driving to relearn or switch over to the new wheel set. This all worked last year. I went from a long drive for the holidays and after about 30-40 mins it gave a malfunction error. I tried to hit the switch wheel set again to restart it, but that didn't work so had the yellow light on my dash for the week. Now I came back home and get a reading again in my garage and it dissappears when I drive off and I don't have a yellow light anymore.

Any suggestions? It would be nice to avoid the dealer on such a simple problem, but believe this may mean I purchase a scan tool and TPWS relearn tool?
