as HipMF stated, I had this happen once in a blue moon, but never could even look into it because it would be gone before I could.
for the brake light circuit code, try re-seating the taillight brake bulbs. historically, that always worked for me. I think they shake loose and the slight short causes the code.

Thanks for the replies. 
The only thing l have done was changing the ccm, since that was what l read on just about every forum post about the issue. Problem occured for the first time just a couple days ago. It’s hard to search for this because most of the threads/results are how to fix the individual codes.
I’ll have to get out the ol multimeter. As for loose connection from hitting a bump this is also very possible. Seems to only go crazy with loads of codes when driving on a less than ideal road.
As for the brake pedal switch l don’t think that is the case because the circuit code didn’t show up until all of the others did as well, and the brake lights are working fine along with everything else it says is wrong. However since it’s the only persistent code, and I’ve read that it comes on even when the lights do work when testing, whos to say they do every time. it’s possible that one is a real issue.
Thanks again!
 

welp, I finished some projects finally.
i used a 3rd cluster to steal the display LCD and finally got the cluster 100% working again
glued one of the door panels back together
got the ebrake unseized
new console surround installed
aux pump and heater valve rebuilt and installed in the car. new coolant added.

 
Steering components 100% replaced. new idler arm, new tie rods, new center drag link. 55mph shimmy is finally gone again. 

 
the remaining three brake calipers (replaced one in spring) all seems to be at different levels of 'stuck', so I just replaced everything.
bottom of the ocean or winter wisconsin car? I think the partial seizing led to extra heat which accelerated the rust on these. 

before:

new parts:

after:

 
then, I took some pictures to be used for selling the car:





 
then, before I could blink, the car was sold. gonna miss this one, we had a lot of great adventures.

This has abc so even more expensive to fix 
luckily the owner before me replaced the front two struts and pump with warranty.
