So I’ve researched here and started my trouble shooting on the center diff lock because it won’t engage. I checked the fuses, and tried a road test to see if it’s locked and the bulb is just burned out. Near were to blame. Now I’m going to bench test the center diff control module, however when I pulled the li k panel I don’t see it. I think it is suppose to be a back square box but I don’t see it. What am I missing guys?
