Dropped rear suspension. This even possible w/ OBD11?

So I was messing around with obd11 in the driveway for a good half hour trying going into basic settings and output tests I probably shouldn't have been touching and I back out of the driveway after doing a ton of random stuff, and instantly it feels like I have a flat tire. Cannot be driven like this. Pull back into driveway and notice the entire rear suspension has dropped like 6" and the rear shocks are fully extended.

I had hit a pothole pretty bad earlier in the day and also had a 100lb compressor in the trunk for a bit earlier but didn't notice anything until after using OBD11. I don't even have suspension as a control module tho.

Visually nothing looks wrong except that the rear suspension is like 2" off the ground now.

This something that's even possible to do with obd11? My driveway is on an incline so maybe hit some basic setting where it tried to level itself to the incline? Coils are fully depressed and shocks fully extended. Before or post my history I just wanna know is that even possible to do with obd11? I'd think everyone would be lowering their cars with obd11 if it was possible. Or is it a mechanical failure?

Weirdly the car doesn't look any lower until you take close look at the rear suspension
