ABS, Traction and Parking Brake lights on?

Hi I'm Linwood. A couple of weeks after a hard front dive in a huge pot hole my abs, traction control and brake lights stay on and together. Sometimes they don't come on when I first start the van, but when I begin moving inside of 30 seconds they click on in unison! I'm told I won't be able to get a passing inspection(6/2025) because of the brake light being on always even though it isn't even engaged. Thing is, parking brake is fine, vehicle runs fine, but a mechanic said its an electrical issue and they can't help. I've heard 1k to 10k for repair and I won't have use of my van for 3 or more days. I could rent a vehicle but for how long? We got this one vehicle and we not rich - what do you suggest? Please?
. Maybe I could do it myself.
(If I replace the abs sensor cords, could that help.)
