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 RU-vid as well!
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.
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.
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
