![]() 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. Joe

![]() 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?
