Just found this::::Mazda6 vehicles with VINs lower than JM1 GJ ****** 160470 (produced before November 21, 2013)After many months and 5 dealer trips, a case opened with Mazda, and threats over invoking the lemon law, my TPMS issues were resolved with the replacement of the DSC/HU unit that controls the TPMS stuff. My TPMS exhibited similar symptoms ever since delivery. Essentially the issue was the DSC/HU refusing to accept the "learned" information and reporting the TPMS light to indicate its refusal to learn. As most normal owners would, I checked pressure and reset using the button. Apparently, the button erases any and all diagnostic log information so if your problem continues, DON'T touch the button... take it to a dealer with the light on.Apparently there are general problems with some of these DSC/HU units, as there is a TSB on a similar subject that resolves with a replacement unit. It is TSB 02-001/14.
