Techstream/TIS help

Hi All,

I signed up for two days of TIS use yesterday and when I launch Techstream and do the ECU health check, it shows an update available for my engine ECU. Ok, I click "YES" and it brings me to the TIS login. I login and it takes me to a white screen with the message "There was an error in the page you requested. Please contact administrator."

The same happens when I try to launch TIS from the Techstream start page or independently of techstream. Help.

Once you have TS installed, you can just use the CUW files found here:
https://www.tacomaworld.com/threads/software-update-for-the-manual.562550/

Double clicking on T-0033-18.cuw will launch the process and is for 2016 and 2017 Tacos with ECU IDs of 04B10, 04B11, and 04B12. Applying the update will give you 04B13.

 

Awesome man, thank you!

 

No problem!

You're welcome.

 

Is there an official website where we can download TechStream and/or the ECU files?

No offense.. but I'm not installing an executable on my computer from some random domain nor will I flash a file to my truck that's compiled from an unknown origin. I work in the computer security industry so admittedly am more cautious (paranoid?) than most.

Thank you in advance for any info on sourcing directly from Toyota or official websites.

 

Sure - if you pay the subscription.

Thank you. The $65 two day option sounds appropriate for my needs.
