......where are you located?I ask because someone on here may know a dealer who can fix you up.I know the service manager at the dealer where I got my truck,I had told him that i saw a Tech 2 for sale,he said I would have to have a way to update it and if I ran into a problem he probably could it updated along with theirs,however that is done....had my wife take it in and they like staring at her nice boobs lol.
Mine use to come on at 57psi. You should set the pressure at the proper psi for your tire and not over inflate because of the stupid TPMS. It will make them wear incorretly, and like you said a bad ride. Find a dealer that will recalibrate the TPMS.What pressure does it alarm at? I just pressured my 35" toyos to 60 psi to get it to clear but it drops to 58-60 when cold and no alarm. Truck rides alot rougher now though. Not sure whats worse, staring at the light or a little rougher ride.
