I did the TPMS canister mod ,
set the tires to 2nd set,
can is at 50psi , tried lower psi also .
getting a low pressure light still...
Did I miss something?

 

I think it has to be set to main. if you set it to 2nd set and there isn't a second set then you get the low tire or flashing tpms.

 

Did you program them yourself or did dealer do it?

 

This is the 2nd set , main are in the stock wheels, and yeah I programmed them myself,
Since its reading low pressure and not check system I'm assuming that part was done correctly...

 

I didn't think you could program tpms sensors yourself?

 

Sounds like its working - I had to seal the TPMS canister twice to finally get it to stop leaking. It was fine around 20 PSI but leaked after 35

You can, with the toyota techstream software & cable

 

Yup, you can register the tpms yourself with tech stream, and I wanted to turn of my drl's.....
the can is holding air , can't figure or why it's still reading low pressure ,

 

Ok , lol I think I figured out the problem .
When I first put air in the can the cap blew off along with the filling and a sensor, turns out 2 sensors blew out , jus found it on the floor in the garage, damn damn damn

 

...how many people really have their own tech stream/ cable...

 

there are affordable cables out there now (<$30)......
