I have a 2011 Ram 2500 with the 5.7 Hemi. I got the truck from auction with some issues. It has around 39K miles on it. I have replaced the PCM with a refurbished unit from Dorman. This was done to correct a transmission solenoid error, which is now solved. When I got the truck, #1 coil pack had been removed, injector was unplugged, and the throttle body was nowhere to be found. I found that it had 4 clogged injectors, now it's running fine.
The persistent problem that I have is with the lights. It looks like someone cut the rear harness, possibly while the wires were still live. I've found some diagrams that show wiring colors at the taillights, but the wires at the main wiring loom (near the spare tire location) are different. So far, if I remember correctly, I have right tail light working, and on the trailer plug I have 12+, ground, brake. and parking light.
In the front, the headlights come on with the parking light switch, and the parking lights come on with the headlight switch. I tried the switch in another truck, and it's working fine. I have tried 2 known good TIPM units, which made no change. 3rd/ center brake light doesn't work either. Turn signals work on the rearview mirrors, but I don't think anywhere else.
I also have no fuel level, no code.
I haven't seen any wires that look damaged. The truck was probably wrecked, but any body damage it had was already repaired before I got it.
So, my questions would be: Does anyone have wiring diagrams for the rear? Is there another control module somewhere other than the TIPM? Where else might I look for the cause of this issue?
