I’ve been researching this issue with my 2014 Cummins for two weeks..... this is by far THE BEST diagnosis video in this issue I have found...... bravo sir! 👏🏽
Thank you Bernie. A friend of mine dropped his truck and asked me to install a new VGT actuator or module. The easy part was draining and removing the part. It's 2014 dodge 2500. The did have the loss of comm code and the nox code as well. I tried to get the new actuator to talk to my scan tool for a precalibration. I did reset all codes twice. I still could not get my scan tool to talk to the actuator for a precal. I knew that if I had installed the new actuator or module I might get it fried too. I could move the vanes manually. I reinstalled the old actuator again and tried to move it. All I got was loss of comm again. I has suspected a cooked wire because I could not get the actuator to precal. I don't have a scope . so I stopped and called the owner and let him know I am out of options to further trouble shoot. I told my friend. He does not owe me no $$ for my trouble shooting. After all I didn't find the true cause. Because I could not read the can buss values.
Was there any resolution to this issue? I’m asking because my turbo and actuator (city diesel) are good but I’m still having a U010C comm loss code that I can’t figure out.
How do I go about finding a real mechanic that I can trust and knows this much knowledge? Not someone that just wants money and to upsell everything. Great video.
@Automotive Test Solutions. I would be interested to know, following this diagnostic process, once you actually removed the actuator, allowing you to manually move the vanes in the turbo, were you able to physically confirm they were stuck? That information and confirmation would be good to know as part of actually confirming the theory from the diagnostics that were run.
You are above and beyond smart. Your diagnostics show a REAL understanding of system. Made it easy to understand theory of what these idiots have put together. Just wish I had equipment you have and training. Too late for that(70yrs. old) so I'll leave it to techs like you. Thanks for video.
i have a similar problem with p003a actuator and nox p2bac, module communication for abs, amp for audio, body control, and climate control, this truck is 2016 6.7 with 35k miles, when i try to clear codes it returns with same codes, seemingly a ground possibly? or fuse, what do you make of this?
Bernie, really excellent and impressive the way you tackle and fix those problems not to many can do what you do i think part of it is ur experience in the field as always AWESOME approach really appreciate ur time and very enjoyable to watch and learn from the MASTER. Cheeeeeeeers
Just watched video AGAIN. Was wondering if when you take turbo out to clean vanes would you even suggest replacing stock module (with plastic gear) with aftermarket unit that has metal gear, more robust electronics and supposed doesn't require programming? Just curious
I think this is what happened to my truck first I was getting the nox sensor code a few months passed and then I started getting the u010c codes. I also noticed my exhaust brake started sticking and finally the vgt acuator failed because it was over worked now I have all sorts of codes and the exhaust brake doesn’t work anymore
Dodge engineers are kinda silly. How do you design a module that basically kills itself trying to move the vanes AND put it beside a 1000+ degree turbo.
The vanes in a Holset don't swing or rotate. The vanes are fixed. It is their exposure to exhaust flow that is varied. Communication on my truck is good but the exposure position is stuck
To be honest I would of replaced the module if there wasnt tbs's or videos like this. Before I replace a module I do as much research as I can that's for lesson it helps tons.
Thank you for explaining that. The heavy carbon on the turbo vanes that is causing the problem is due to what? Very high mileage? Lots of low speed stop and go? Heavy towing? All the above.....or ? Besides the codes, what symptoms are present? Your theory of operation zero's in on the problem, I'm also looking for the root cause of the problem.
BREAKING NEWS ALERT!! The main problem is that it takes computers to fix vehicles now. Let’s make them more simple and go back to being mechanics not computer geeks
Not gonna lie if I was doing this I would end up putting the module in unless there was some specific information in the description and operation for this system that says there's pretty much no current limit for the vanes lmao I would just assume it was shorting internally.

Anyone planning on replacing your actuator needs this videos information. Fantastic..
Excellent video as usual Bernie. Lots of great info. Thank you for taking the time to share your wisdom!

You don’t have to make these vids but you do.... thank you for that. We are all learning so much with each nugget of wisdom

Thanks. I'm just starting watching your videos because I have learned for what u taught us with the Spanish UA-camr. Thank you sir
Thanks man 🤝 Bernie is the best teacher and technician .

Having this exact issue with my 2014 Ram.. Thanks
thank you . We are all learning so much with each nugget of wisdom
That is a very subtle failure to catch. Very impressive diagnosis. Thanks for sharing!
Sounds like Chrysler forgot to put in logic for an over current condition on the VGT control or needs to reduce the threshold.
Thank you for your time and expertise Mr.Thopson!Master in craft!

These are just great. Thanks for all your hard work, and for sharing your skill and experience with us.

excellent diagnosis Greetings from Lima Peru
Question: can you read a high amp draw with the amp meter at the turbo wire. if it is over 6 amp draw = carbon build up. I don't have a scope.
Thanks for sharing Bernie 😁. It is already a pleasure.
Thank you Bernie! Great video. Makes me want to get a ATS Scope and get rid of my Pico! 😈
Too cool Bernie dealing with a school bus turbo same problem.thanks for sharing learn a lot from you .thanks again
Perfect explanation
You are the man!!!
Impresionante diagnóstico, excelente manejo del equipo y del conocimiento técnico.
Gods work 🙏🏼
Wow. Thank you for this knowledge.
u rock. confirmed my suspicion
Большое спасибо,сэр
Awesome diagnosis as usual Bernie! What's the cause of the carbon buildup?
Egr
Just watched video AGAIN. Was wondering if when you take turbo out to clean vanes would you even suggest replacing stock module (with plastic gear) with aftermarket unit that has metal gear, more robust electronics and supposed doesn't require programming? Just curious
Very good diagnosis.
Awesome... Thanks for sharing Bernie. Cheers.
I wish I could get you to diagnose my turbo/ actuator on my truck. Dealership tried to do exactly what you said....
Thanks for the great video.
I think this is what happened to my truck first I was getting the nox sensor code a few months passed and then I started getting the u010c codes. I also noticed my exhaust brake started sticking and finally the vgt acuator failed because it was over worked now I have all sorts of codes and the exhaust brake doesn’t work anymore
Super thanks I’m going to be a genius a super valuable information....👍👍👍👍👍🤝🤝🤝🤝🤝🤝🤝

Where can I find a great shop like yours in the Phoenix area? V.

👍 great video
Brilliant information thank you Sir, cheers sandy
Awesome vid as usual. Any particular reason you used the Autel instead of the escan?
Outstanding!
Why does the actuator position change on the autel?
So how do you remove carbon buildup?
I'm having this exact same issue on my 2014 ram with 67k miles on it. Out of warranty due to time
To be honest I would of replaced the module if there wasnt tbs's or videos like this. Before I replace a module I do as much research as I can that's for lesson it helps tons.
Nice one.
Do you have any insight on code p006e
Bernie is the car whisperer
Good.
thanks

Your theory of operation zero's in on the problem, I'm also looking for the root cause of the problem.
I’m experiencing similar symptoms on my truck I think the heavy carbon is caused by long idle periods, and also not using the exhaust brake
Also the exhaust gas recirculation system
BREAKING NEWS ALERT!!
The main problem is that it takes computers to fix vehicles now. Let’s make them more simple and go back to being mechanics not computer geeks
That would be a turbo actuator, I just fixed that
Not gonna lie if I was doing this I would end up putting the module in unless there was some specific information in the description and operation for this system that says there's pretty much no current limit for the vanes lmao I would just assume it was shorting internally.
These diag beat anything else posted on youtube. All of them.
You need to just quit fucking around and replace the vgt actuator
