"No Bus" what is wrong and how can I fix it?

Update: replaced Front Control Module and still shows No BU5. Guess I have got to now try replacing the module on the firewall (it is the one with 3 plugs) as I do not know where other modules are or where to go next. Any ideas would be helpful.

Okay, when I plug in using a scan program (obd doctor) I can get a tachometer and speedometer, but on codes and not sure what I am looking for.

Hi KASEKENNY1, I got a code reader and it is telling me p1698, which is tranny module. Unplugged the tranny mod and after clearing code tried again and I get the code again. I am going to start tracing wiring. Will let you know what I find.

I have the truck listed above it is a 1500. Once a week my truck stalls and I get code no BUS. I turn the key three times and it reset and starts, then I am good for four or five days and it does the same thing.

Update. I bit the bullet and took my truck to dealer. $686.00 Canadian later and although there are still some problems I now have brake lights, signal lights, gauges, tachometer, speedometer and almost everything is working. I was right in that it was a broken wire and was causing a short that somehow got into the canbus and caused system to stop. Now have to do rewiring of some circuits. You will not believe what/where this problem is.

So my problem is in the odometer spot it reads no bus and my check engine light is on I have had 3 different code readers read it and pulls no codes but check engine light is still on I have heard the no bus will make it do that. The truck seems to run fine gauges work it doesn't die randomly nothing out of the normal but I have no clue what to do my tags are out and I can't get inspection with the light on I would appreciate help I am a younger guy with not enough money to take it to I dealership

I had auto zone read it and 2 mechanics and one of them had the really big nice snap on one said it was a high dollar code reader he didn't know why it wouldn't pull anything up but for me to have them run through my truck and have them run test it is 100 dollars just to diagnose

Ok thank you anyways for trying and could you send pics one more time they didn't show up on last message

Hello and thanks in advance.
Brief background- Father and I removed transmission and changed torque converter. Truck started and was running fine during fluid fill up, I actually turned it off and restarted several times. When the fluid level was believed to be correct, and we could feel the transmission engage in both reverse and drive. I backed the truck up about 15 feet to turn around then I decided to shut it off to check/make sure that the transfercase was in 2-high before driving down the road. I ran the shifter on the transfercase through the four different gears and made sure that I was indeed in 2-high and when I tried to start it back up I could not. The motor would turn over but not start. I had no readings at the gauges and could not hear the fuel pump turn on at all. I then looked at the odometer and read the words "no bus". I have since looked up what that phrase means but am very curious to know how what happened in the time I shut the truck down to check the position of the transfercase shift lever and the failed restart.

I have not had a whole lot of time to spend working on this problem with my busy work schedule, but the one thing that I do want to do before continuing the work on my truck is make sure that the electrical and sensor connections at the transmission are good and at the same time replace a wire/plug that was damaged by a jack malfunction at the front axle during the torque converter change. I am not sure if this damaged wire came into play during my transfer case run through of the gears or not but is seems like a good baseline to have before proceeding any further.

Intermittent start problem. Trucks runs good can die when driving with no notice, sometimes will start after one minute, Mileage blinks then shows (No Bus). I have no code with OBD2. Had it in a dodge repair shop, no luck finding problem. No mechanic seems to know what (No Bus) means. Can you please help.
Thank You
