Hello today my TPMS light came on my car it’s not the low tire pressure light it just says system error and it won’t show the tires psi like it usually does. I made sure to pump air in all 4 tires drove it for 20 min above 50 mph and it still won’t go away . I can’t seem to find the reset button under the steering wheel. Any help Is appreciated!

It sounds like the TPMS control unit has gone out. To be sure let's perform a CAN scan, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon. here is a video to show you how:

Also, check the fuses, here is the location of the TPMS controller so you can swap it out, I would check for a used unit on Ebay. Check out the images (below). Please let us know what happens.
