Alright, 2013 Ram Sport; 1500, 5.7, 8 speed trans; so I've been reading a lot of the threads and information on the random problem. While my truck is off and key FOB in the house, the Cluster lights will turn on with the message to press brake and hit start button and then go off. It does this every 30 to 45 seconds. So with all the reading and what not here is what I've done.
- New battery, (It was bad needed new anyway)
- pulled the TIPM out and checked for any corrosion (non)
- Pulled F60 fuse but that didn't resolve so I haven't checked the I230 connector
- Disconnected and checked the HVAC control module (I could hear the flaps opening and closing when lights came on).
- Checked the Shifter / Transfer case module
- I pulled a bunch of fuses nothing seemed to help
So I used a basic scanner and got the U0140 code, lost communication with Body Control Module, I then linked up my Alpha OBD and got the following faults.
- C1503 Tire Pressure sensor 3 (This could just be from when I got my new wheels and tires)?
- Passenger Door Module B21DD, B210C
- Driver Door Module; B210C, B21DD, And B1F05 this last one is for Electrochromatic Mirror Control Circuit.
- Body Control Module; B1707 and B170B (reverse lights wondering if it's because I put the 5th gen tails in and didn't change to LED?) and then B2312 Wiper on/Off control.
The door modules would make sense because it seems like the truck is thinking someone is opening or unlocking the door. I'm Just popping in to see if anyone has ANY other ideas. I've been through all of the threads. The things I"m going to try to night is pull the door panels and disconnect the door modules to see if the problem still happens. I also saw there is an inline on the bottom frame rail under the driver side, I will also crawl under there to see if there is any water or corrosion. I was hoping someone had some more suggestions on where to go, or what to try. Sorry this was so long.
