I had a problem with that when i updated it and autel walk me threw it so i could changed it to usa and then we reprogramed the sensers .
The tool is TS508
Now 2018 cadillac Escalade in that year will go 315mhz or 433mhz.
Its my Daughters Truck. she had a 2017 tahoe and just bought new rims for it so they swiped them at the Dealer and the light was on so i just put new sensors in the wheels and there Autel .
So how can i find out what that cadillac is 315 or 433 ? Dealer ? it is set for 315 now.
