Anyone have a professional TIS account?

I was looking to see if I could upgrade the software on my integrated trailer brake controller using techstream. It seems like you need a professional account to get the calibration files. Based on the TSB I believe it's calibration file 8954F0C013.

So path would be something like:

https://techinfo.toyota.com/t3portal/calibration/8954F0C013

Anyone have access to that file?

 

Did you ever manage to do the brake controller update? I'm also needing to do this.

 

Nope, never was able to update the firmware. Two years ago the brake controller threw warnings then stopped working at all. I had to replace it and the new unit came with the latest version.

 

I just took possession of my father in-laws 2016 Tundra and discovered that there is a update available. The controller works but I do tow a 6k TT so I want the update. If you don't mind me asking what did the Toyota brake controller cost.
