    Can't reset TPMS on 2015 GM Encore

    First I'm a rookie with American vehicles, but now retired 40+ yrs on VW.
    That said I can't reset the TPMS Here's what I did
    1- scan vehicle
    2- TPM system
    3- Functions
    4- select learn
    5- using cheap amazon activator and nothing happens, no beep after vehicle parking light is on
    6- if I did the above correct I presume the cheap amazon tool is faulty?

    thx

    Make sure your activator has 315mhz as your tpms sensors or else it won't ping them.

      Even when the service procedures don't mention it, you can often activate the TPMS sensors on GM vehicles by inflating or deflating them a few pounds.
      So instead of using your activation tool, drop some air out of the tires in the same order that you'd activate them. I bet it works.

        Got it done! I was pointing the tool to the valve stem, but when pointed to the tire beside the rim it worked. Kinda odd because I thought the stem was also the sensor antenna?
