I recently bought a theft recovery from. The sheriff's auction, and even with the issues I'm still ahead. Had to change driver's side upper trailing arm, as well as calipers and rotor on all four corners. Once I got it mostly road worthy I drove it the 3 blocks to my closest Oreilly auto parts to run a code check. I neglected to write all of the codes down, but I kept seeing several for prop shaft sensor signal nonexistent, wheel speed sensor missing, and the like. I apologize on my wording, but you get the jest. My awd doesn't work, and I only have red currently. I've checked all fuses, but cannot find my issue. Since awd is automatic on my model, is there a control box I can have tested?
