Customer states this 2014 GMC Sierra is a no crank almost every morning but if he waits till later in the day it starts right up and doesn't have any problems.
Great work Jake! I know and understand that making these videos takes time and effort and as a fellow mechanic I just want you to know that we appreciate you and some of the other great mechanics on UA-cam as well!
I am responding to the video as it plays today. Your opening portion showed the Health Report with 19 modules, after the 5:00 range you don't have comms with the BCM and it looks like your scan tool is reporting only 15 modules, this is very important information and we need to keep records of this data, on this exact trim of truck there appear to be 19 modules available, do we know what they are so we know which 4 are missing at the moment? Another bit of data to collect for our library or database. At time 7:30 those 4 modules are there at the end of your schematic pointing to a problem prior to the BCM on the CAN C Bus Line. Your HMI had a code earlier in the video so I believe at least one wire is ok there? A problem I have with some techs, you show the bad CAN C waveform and missing modules with codes but you did not show the final repair verification to us with the full list of modules, assumed to be 19. Overall a great video, thank you again. You will notice the long curve in the waveform, this is due to high resistance which you found pretty quickly. May I please ask for a full list of modules or module count in future videos, your scanner shows this info, much appreciated.
The root cause is most likely that the abrasion taped harness is able to vibrate and put stress on the connector pin. After the repair the module and the harness should be tie-wrapped so they cannot move in relation to one another.
Dont know how many 14's i had towed in that would not start because the automatic power seat moved forward and pinched wires under the driver seat. Move the seat back and they started right up
If that's not a fix, then nothing is. Great job. Fantastic diagnostic method and walking us through your thought process. Thank you very much.
I love the way you go through your diagnosis procedure, it truly shows that you know what you do.Great work indeed.
This was just excellent all around. Tons of great info. You should have a million subscribers.
Awesome diagnostic process! Logical, fast and effective. Great tip about the terminal part #...used all data for years, never noticed that. Lol
Nice diag, and No Parts Required repair! ;)
@PineHollowAutoDiagnostics Who doesn't like a Russian repair 😊
Another great teacher on YT! Appreciate the knowledge!
Awesome thought process! Thanks for sharing, gotta love the terminal tension ones...
audio seems to be very quiet for me

Always a learning one with you. Great work !!!
As always you make it look easy.. Love watching you
Enjoyed your flow process. ❤️
As always you make it seem so simple, though surely you are on top of this technology. Thanks for sharing and being patient with us normal folks!
Great job brother! Thanks for sharing with us. Great diagnostic process!
that was amazing. you are a great teacher. thanks.
Awesome video man... Keep it up... We need to see your channel growing
New sub here. Keep the videos coming! Great work!
Love the videos very informative
Nice video, please keep them coming
Terrific find!
I enjoy watching your videos, but what i realized, the room im in has to be silent. im at the gym doing cardio. I honestly can’t hear 💩. 😂
You are genius. I always learn from you
I thought this was part three for a moment there😒😒lol. Another great video with useful information.
@@autodiagyt Nice one glad its sorted. no rush it will be worth the wait I'm sure.👍👍
great information! Thanks.
Great content!!!!
Informative
Thanks for great vedio
Thank you 👍
Anyone else having a very low audio problem?
Worked fine for me.
Yes I am
Very low volume
Would like to have seen the after fix scope pattern
Excellent diog!! When u had signal I thought for sure you were dealing with powers and grounds.

Yup

👍🏻👍🏻👍🏻👍🏻🌷
Technically this kind of an issue should be a warranty claim no matter the mileage or age.
Fair point.
Could you have put a 120 ohm resistor in line at the hmi to verify you need to pull the telematic?...getting to the telematics is a bitch
Volume low
We can hardly here you talk
