Truck ABS, and trailer ABS lights come on and dash lights go out.

Wheel sensor.

 

It could be any number of things - from a bad wheel sensor, or a bad ground, a wire chuffed, or up to a bad ecu/ecm.

 

he's talking about a sensor that monitors the wheels the tires are mounted on. ABS systems have sensors to detect when one of the rolling wheels stops rolling (skidding) or is rolling at a grossly different rate than the other monitored wheels and then reduces brake pressure to that wheel.

 

It sounds like a sensor or wiring problem. Unless you see some unusual and unexplained wires hanging down there is nothing you can do to fix it. It needs to go to a shop, probably a dealership.

 

Before you go to the stealer, take a minute or two to look in the battery box for a loose wire. I've had 3 Centurys and all of them had some really janky factory power feed wires in there that would come loose from time to time. Especially when a previous owner repaired it the last time without using proper heat shrink terminals and the like, and a crappy roadside repair fell off again. While you're in there, replace any cable terminals that have any sign of green cancer and tighten everything up.

 

Loose power/ground wire. I have a 06. Abs light comes on all the time, trailer abs too. If it doesn’t affect any driving it’s just another annoying wire.

 

The fact you mention the dash reboot itself would steer me toward a power/ground issue with a module, rather than an ABS problem specifically.
