2006 GX470-200k

Yesterday I noticed that the VSC Trac Off light came on. I thought maybe I had bumped the button, but it wouldn't go back on when I tried. The service engine light did not come on however. I thought I'd hook my code reader up to it and see what showed up and I got a whole bunch of new codes that I've never seen before. Since replacing my MAF last year, I always have:
P0300
P0100
P0102
P0103
That's "normal." The car runs fine with no check engine light showing. If I didn't know the codes were there, I'd have no idea that the car thought anything was wrong.
That said, when I checked for codes today with the VSC Trac Off light showing, I got the following new set of codes:
P0125
P0128
P0420
P0430
P0456
P0500
P050A
P050B
P0705
P0705
P0722
P0751
P0756
If you believe the codes, it looks like a total meltdown. That said, I'm trying to trace it back to a source obviously.

The car is driving "ok" but the wheels want to chirp (skid stop) at low speeds. I was able to drive it a few miles how with no issues when it happened however. Thanks in advance for any help.

 

I’d try I cap discharge.

Just disconnect the battery and discharge the capacitors... see what comes back
