There's a 3 digit subcode that goes with those error codes... It'd help us help us help you if we could find out what they are?

 

As we often mention on here in discussions with inverter error codes is the inverter handles so many different aspects of the high voltage system, that problems with other systems can falsely point to the inverter as the problem because the inverter has to deal with that problem more than the other systems. I still have a replacement inverter on my parts racks from a few years ago that I never needed to use because of this. So now's the time to get after the rest of hybrid system with cleaning, inspection and maintenance.

 

i have read there is a snoflake to click on in tech stream that gives the 3 digit sub code

 

Hopefully these images can help those that need to know the 3 digit INF, detailed code, sub code, etc.



Then look for :

 

unfortunately, no. there are lots of threads here, and success is hit or miss, because it is a black market product

 

Techstream itself isn't a black market product. If you download it straight from Toyota and use their activation keys ($65 for two days of use), there's nothing seamy to worry about.

Some of the cheaper J2534 dongles being sold online will tout that they come with a copy of Techstream that might possibly forget to check its activation key. Those, of course, are not official copies, and can present some challenges in setup. People using those tend to dedicate an old beater laptop and make sure not to use it for anything important.

 

Which version are you attempting to install on what operating system?

 

My cheap cracked software license on the very first day said it was good for 9,999 days... Seems reasonable?

 

Any updates?

If stuck, just let us know and we will try to assist.
