I should’ve just done this first because I ended up in the same boat bought sensors and switches now computer then it would’ve been vice versa Lol just replace your pcm if you’ve checked all wires that would cause no bus. crack it open it’s easy if it’s a 2000 like mine. Got mine from flagship read great reviews will be here Thursday which is sad cause I couldn’t use the Jeep in this giant snow we had over the weekend
