1988-1994 Chevrolet GMT400 K3500 extended cab v 1.0.1

I'm trying to figure out what's causing the 1988-1994 Chevrolet Silverado K3500's "work in progress" current problem and "do not drive in water" message. If you want, feel free to fix her up.
repaired the rear bumper and its attachments; the water message was caused by a broken object.
Options include clear or tinted windows, a plow and attacher, paint, optional bumpers, optional mirrors, and a rack with or without LED pods.
