Traction control warning light & beep suddenly more senstive, goes off more often

2013 Prius 84,000 miles garage kept The traction control light and beep are popping off more often over the last week or so on bumps or uneven roads that wouldn't ordinarily trigger it, like it has become more sensitive to the road and only lights up and beeps for like a half a second then goes away. if it's a smooth road no warnings or beeps at all. Tire pressures and tires are fine. Brake fluid has never been changed, probably not the best idea, but brakes are perfect, topped off if ever needed.
Dare I say, Nothing at all has ever gone wrong on this car in the 84,000 miles, changed oil every 5k, changed both coolants, changed the EGR cooler & valve to a new one about 6 month back, does not burn a drop of oil, guess I'm lucky.
Looking to change the intake in the next few month to one I bough on ebay that I already cleaned up , so i don't have to take it off and quickly clean it, and put it back.in.
Wondering if it could be my front struts ?
I can push the rear cargo area down above the strut, and it moves a little up and down, correctly I think, the front I can't push down at all, if I grab the fender walI I can move it up/down about a 1/2" or so (maybe fronts are a lot harder to push or I'm not strong enough)
I do have an OBD2 dongle, have not used it and the free version of Dr Prius, not sure if that would show anything or do I need a better one with a screen (if so which one?)
any help or advice would be appreciated.

 

Downloaded the program (assuming this screen shot is the right one?) I will pay for the forever one sounds like a good idea I may go into the garage and plug it in and see what I get if my dongle is correct. I see where you can download techstream for free which I did and the installer I do computers for a living so I certainly have an old one here to play with and not worry about my network or malware.
hope its not a hub- sounds expensive, Said there's a good chance that a code was logged of my issue to see what happened which I guess would be a good thing.

 

thanks
Im gonna go in to the garage & see if my dongle works on it
the car to only on or running?

 

I'm in the car with the unit I got my dongle connected but I don't know where to look exactly within the program for abs history

 

Is scanned 131 items I'm sure my car doesn't have all this came up with no DTC found I guess that's a good thing for now

 

So I guess I'm good for now I found a download of techsream I'm going to play with it tomorrow and see if I can actually get it installed & running if I can get that far then I'll buy the appropriate cord for it.

 

Did not see anything about ABS history in their where would it be

 

I did it right correct in that program left side second icon down diagnostic trouble codes it went through 131 and no DTC found which I guess is a good thing if that's the right place

 

This program correct

 

I live in Miami Florida and it's garage kept where are the electrical connectors, I'm guessing front wheels only so I can possibly look I have tons of tools and Jacks and all that stuff though I'm more older unfortunately 66.
For now just leave it alone other than maybe looking at the connectors if you tell me that they're not so hard to get to and where they are and wait till it gets worse?
If I stay on even smooth roads it probably won't go off at all it's when I hit little bumps and stuff like that and sometimes it doesn't when I think it will first thing ever in 12 years that's created an issue Maybe ever dare I say

 

Makes sence thanks
Have you install techstream or have you gotten it and installed it?
Doing some reading I see that there are two files and one of them creates a 32-bit environment so I've been doing computers my whole life I got a hold of a 32 bit version of Windows 10 that I will insult tomorrow. I think i don't need to use the virtual environment but we'll see what happens tomorrow I don't think I can get very far without the dongle connector I'm not even sure the program will come up and I'm not 100% sure which dongle to get
I see them on Amazon from like $17 to 50 something appreciate all this by the way
