No Bus - Truck Possessed- all stock
Hello Everyone and thanks in advance for any tips or advice. I'll try to keep this as direct as I can but at this point I am a ball of emotion. I want to fully Express this issue is with a bone stock 2012, 3500 CTD that currently has 67452 miles on the clock - NOT the result of tuning but it sounds like a ECU issue so it's posted here.
About 6 months ago I took the truck to the dealer because a few of the lights went out in the gauge cluster. As its still under warranty I paid the 100 bucks and they replaced the cluster. A short time later I unplug the trailer with the truck running (nothing wrong with that- right?) and the truck went completely bonkers. Windows went up, windshield wipers came on, dash lit up like a Christmas tree, all the gauges went to 0 "No Bus" appeared on the EVIC. Back to the dealer we go and was told that I probably needed batteries. A couple hundred dollars later new batteries installed and I'm good to go..... WRONG. Heading home from Home Depot and the poltergeists begins again. Back to the dealer I go on 4/2/2019. The dealer had the truck for 2 weeks. Replaced the cluster 2 more times and the TIPM. On 4/17 I received the call, your truck is ready. GREAT.... WELL not really. I get half way home and there is goes again. "NO BUS". Today I check the codes with the key on-off trick and it revealed a P-0606 code. Humm. So, back to the dealer I go, tomorrow.
Understanding once I tune the warranty is most likely void. However, could tuning possibly fix this? I've been waiting for this to be resolved before I place my order with RAY.
The truck seems to be running normal. Starts fine just the gauges, radio, wipers, windows do what they want when this happens.
Do I tune now or wait???????
Thanks again...
I'll update on the progress.
Cheers,

I have the bad habit of shutting down the truck when plugging in / out the trailer. Just an old habit. But unless you have all the lights on, I don't see where it woulg cause a problem.
I wouldn't delete or change anything until its running right in the 1st place. If you do, you'll have hell guessing the problem. Maybe someone can be better help for you on this soon. But I'd have the dealer get it right first if still under warrantee.
@Double R Diesel ... any help ?

My honest opinion is the pcm is failing. The P0606 is pretty much confirmation of it. Get your pcm replaced before doing anything else to the truck.

Copy that - back to the dealer today.
Thanks Again
Re: No Bus - Truck Possessed- all stock
Keep us updated sir! Sorry to hear of all the issues.
Re: No Bus - Truck Possessed- all stock
Will do. At the end of the day just wish I knew what caused it.
Looks like I got the 1 in 30,000 that was defective. :confused:
Thanks for the concern.
Cheers
Re: No Bus - Truck Possessed- all stock
I dropped it off this evening. I keep thinking about the P-0606 code I retrieved with the key cycle method.
P-0606 = PCM Failed its self test. One suggestion is:
Retrieves freeze frame data using an OBD-II scanner. Doing this will provide information as to when the code was set by the PCM, as well as what likely caused the code to be stored.
Will the MM3 retrieve freeze fram data? I may just be looking for a reason not to wait to order the MM3 from Ray. I don't have as much faith in the dealer as I should and if this unit will assist me in diagnosis that would be huge! Im not sure if the key trick shows all the codes. Does the MM3 show the "deep" codes? Can I down load the MM3 user manual before making the purchase. Knowledge is power, it would be beneficial to be able to scan the truck before I speak to the dealer again. Thanks for brain storming.
Cheers
Re: No Bus - Truck Possessed- all stock
Im not clear on whether you truck has a tune on it or not.
Re: No Bus - Truck Possessed- all stock
Dont tune unless your truck is healthy. Make RAM fix it under warranty then drive it a few 100 miles to make sure the problem is resolved. I never had the problem you are describing happen to my truck. 2012 RAM 78k custom tuned at 25k
Re: No Bus - Truck Possessed- all stock
Understood,
The truck is stock at this point. I will not be tuning until it's fixed. I just thought the MM3 had certain diagnostic features built in that would assist me in the knowing the truth.
Just thinking of ordering the unit just to be used as a scan tool.
Thanks,
