New to the forums I have a 2008 6.7 I have an abs light on and my 4x4 won’t engage I believe it’s an Electrical issue but not positive any advice would be greatly appreciated thank you in advance

Does your truck have a manual transfer case with a shifter in the floor or is it electric-shift with a knob on the instrument panel?

Do you have access to a scan tool? If not, take a trip to the local O'reilly's and have them connect their scan tool and see what DTC's (codes) are set and then go from there.
