ABS & Parking brake light on

I knocked ice off of rear axle only to have my ABS & parking brake light stuck on when I got back in truck . I have brakes but no ABS. Can someone tell me how to find sensor on rear ? I don't see anything obviously loose. Just 2 aggravating lights on my dash !!!!

 

They are bolted on to the front side of the Axle Hub Assembly. One on drivers side and one on passenger side.

It should be fairly obvious when looking under the truck. It is the only component on the wheel hub with an electrical cable going to it.

You probably damaged or unplugged the cable when knocking the ice off.

 

It was a loose ABS connector on right rear. Thanx a lot man.
