Here is my experience with VXDIAG VCX NANO Toyota J2534 and the crack version Techstream software. I actually installed the tool on a small Samsung Notebook (Windows 7, 10.1″) which has excellent battery life.
1st car:
Tested on my C-HR, it works quite well (with a certain slowness). We have access to an incredible amount of data (particularly the hybrid part).
2nd car:
Little test on the Rx. That works well.
For each system there is a screen giving the possible fault codes, a screen giving the state of the system with the parameters then an “active test” screen.
For example, for the “air conditioning” system, I chose a simple command:
For the air conditioning there is an interesting function, which varies the maximum speed of the compressor (probably “Target Speed”).
As regards the active tests of the hybrid system, they are to be used in a particular context.
The only ones that can be launched without any particular procedure (apart from the ventilation control) are the “Inspection Mode” (used for example for pollution control).
You can set to “ON” or “OFF” from the PC and see the status on the control screen:
The hybrid function is copious (6 pages)
with interesting commands:
and others that seem risky.
3rd car:
I have been using Toyota Techstream for a long time to check the good condition of my Land Cruiser injectors. There was clearly a lot less stuff on my Land Cruiser.
On hybrids, in the absence of defects, I do this out of curiosity. It’s quite fascinating to have access to all these parameters. Tracking the main battery status sounds interesting to me but there are quite a few things that get done with Hybrid Assistant.
I had fun finding in RX45h manual the use case of the active test that I mentioned.
TechStream is the ideal tool to associate with the repair manual!
