I have a LVD/CECU issue. So far, checked batteries, fuses, mega fuse, it all started after using the APU I believe, coincidence? Maybe. Also, dome lights, door lights, some outlets now off, don't work. Sometimes I get the truck won't start issue, turn the APU on, truck starts up. Last 8 of my VIN# is GD353569
I don't know where the LVD is and if it's CECU controlled and location of the CECU. Not sure we checked the ground, we did read the cab doesn't have a ground to the frame, it's all grounded through the ECM/CECU, so a rogue GPS, CB, Samsara ground to the cab can cause this as well? Any help moving forward is greatly appreciated.
So many stories of this same issue on so many trucks on here. I can't find many that finish this issue. I'd rather not jump it, I want to know what's wrong, so any suggestions, ill try it, post results, and keep going until I can figure it out and post pictures, with hopefully the results to help others.
Thank you all for any help moving forward
