I have viewed and inspected all the ground locations listed with AllData. I had even sanded each location and put a good amount of dielectric grease on each during reassembly. I would agree that it sound like a ground issue. But all of them are checking out good! I have the following things not working. -Fuel gauge -Outside temp is reading -40 -Brake pad sensor malfunction -Service Parking brake, but that is working -Traction control light on -TPMS light on The following codes descriptions. Invalid data received from body control module Lost comm with TCM Lost comm with ECM invalid data from front and rear brake wear circuit

Hey guys. I have no communication with multiple modules on my truck. I have been searching and searching, nut can't find related threads. I have been fighting an issue for about three days. The truck has been rebuilt. I put a frame under it and a lot of other repairs. I had it running and driving, but something was running my batteries down completely overnight. I could not get my batteries to hold a charge any more and this is when the issue started while I was starting to troubleshoot. I am getting a U0100 code. I have communication with my BCM. I do not have it with the ECM, TCM, TBCM (Trailer Brake Control Module). I need help!
