I've only used this for a couple of days on two private cars. I received software version 3.13 that contained incorrect relearn information for my 2011 Colorado. I had to contact support. for instructions on how to get the latest V3.20 update which changed the menu and contained the correct learning information. I had to go to their website and find the TS401 (which got 2 matches) and follow one of the links to a page that had a downloads tab with a list of what I needed. It was called V3.20 update and V5.22 update but I was ordered to use V3.20 and they haven't told me what V5.22 is yet so it could be fake. It looks like it's working well so far. My Chevy Colorado's sensors don't seem to report battery health or temperature, but my 2015 Sienna's sensors do. I don't think they report the actual sensor brand and PN. Gauges which I think will make a world of difference as gauges age and batteries die, especially on gauges that don't report battery health. Resources are current.
