CEL Lights Like a x-mas tree

[DropKickJacKs]

This morning I went to start my 21 JLURD and drove it about 100yds, and all the warning lights when on. It said to service the Stability sensor or something like that with warning lights on the dashboard.

It went into limp mode I believe, because it would not shift out of 1st gear. I dove it back to my friends house.
I used my taser and got codes, U1428, U1514-87 , B121C, &U0401.

I cleared the trouble codes and unplugged the battery for like 30 min. I then attempted to start it, and the warning lights were still all there.

I then checked all my fuses and made sure they were seated. I also checked the ( I think ) the CANBUS plugs under the glove compartment door.

I have no clue what happened, but after several attempts, I started it and no codes . I drove it 150 miles home and it was fine .

What do you guys/gals think?

How old is the battery?

it's about 2 months old one of the first things I changed out when the Gremlins started.

So far so good, pushed all the fuses in, replaced both star connectors behind the glovebox, moved the harness further away from the exhaust, and heat wrapped it.

Basically, who knows what fixed it, or if it is fixed .

Same crap happened today, I am going to ditch the taser and see what happens
