Hello Lexus friends,

I am having a very difficult time finding a nice and proper system for diagnosing our 2 Lexi.
The first is an 2004 LS430 and the other is a GS300 from 2004 (Old model).

After searching many hours on the web I found only 2 possible solutions.

The first thing is just a little cable + cd and there are many of them on Ebay. Some are cheap and some are more expensieve. Some are 32b and others are 64b. Then we have many different numbers, the latest, the newest etc. https://www.ebay.com/itm/221720133329

The second option seems the most easy one but thats only temporary.
Its the it2 tester. Why is this a difficult desision? Because they seem all replica's, and maybe there are fake copies of copies!
The average price is $ 500 but when I search deeper Ill find them starting from $ 200 on Aliexpress.

To make everything even more difficult there is allso an it3 system and some system without the little pda like on this page:

=y&SearchText=toyota+intelligent+tester

Last but not least: Whats the Oscilloscoop exactly for and what use is it exactly. Also more choises between normal and high quality ones when you order the it2 tester.

I allready made a topic on the subforum but I really dont get many support because its just not that crowdy over there and I really hope you guys can help me out here.

I cant believe I am the only one having difficulties with this subject.

Many thanks!
