The vcd light came on after i did my body lift all those kays ago but off again pretty quickly.
I definitely uncliped that wire up on the tower (abs?)
If you uncliped when doing the arms even if you didn't I'd check the wiring, unclip and clean blow out inside connections. If you did have it unclipped while grinding you might have some shavings in there?
My next thought would be that it comes on when in 4lo.
Try going into 4hi and small off road drive then 4lo small drive, both forward and backwards then back to 2wd.
Hopefully something like that will fix.
