Answers :

The 4wd switch has been known to be a problem. p2575 is the code for it. Also there is a ground problem. The wires are on the frame near the drivers side front door. Remove the wires, clean the undercoating off, use dielectric grease on the terminals and reinstall them. After that spray on some undercoating to cover the area.
