Jimny Diagnostics (via OBDII connection)

I have just bought a more sophisticated OBDII diagnostic tool. This was specifically for my Range Rover Sport and its suspension issues but rather that purchase the low cost single car tool (ie for the Range Rover), I purchased the more sophisticated multi car version as it said  that it supports Suzuki models.
Now my past experience of Suzuki OBDII has been disappointing, most readers only read the basic mandatory OBDII parameters and none of the Suzuki specific ones. The best that I found was SZviewer with a bluetooth dongle. This was a pretty comprehensive scanner but development has stopped and the app withdrawn (the APK is still around but at the risk that it has been hacked). SZViewer also did not offer any control options, it was read only plus DTC Clear
Therefore I wanted to see what this new tool could do. The initial results are promising and therefore I am going to create a video on it. This is your opportunity to ask questions that will be answered (or not) in the video.

Here are the basic modules it has detected and to some extent control (its a bi-directional tool). James will want me to point out that the TPMS errors on his car are "History" and not current, probably when the new tyres were fitted.

The tool is a Launch CRP919X (not sponsored, fully paid for to work on my Range Rover)

Sir,
I have a 2012 gen 3 that happily drives me wherever I point it to. Why should I get a diagnostic scanner?
If  I happen to be able to borrow one, what should I look for in the Jimny's system?
