    Michael Szweda yes Michael but be aware some vehicles do not have CAN at the DLC and use a gateway module. In this case you have to test at a module. There will be more videos in this series, expanding on the topic. 👍

    Good information btw. I am troubleshooting a ford no pcm trans abs instrument cluster communication with our ids scanner. I have power on pin 16 and good ground on chassis and sensor on the dlc. I have a hunch I have one module is causing this. Do I really need a lab scope? Or multimeter

    Good on you taking the time out of your day to make informative videos. A couple of pointers tho. 6 and 14 are CAN high and CAN low because of their voltage differences and the fact that their dominant bits change in voltage the opposite way to each other. They are however both in the same speed network. There can be multiple speeds of network ( as shown in your wiring diagram) Referring to the diagram, i would suspect that was one data link connector but it was split showing two different networks on 2 different pairs of pins 9+17 & 3+11. Also some manufacturers such as psa use wire numbering instead of colours. So all the CAN wires in one network will be 9001 & 9002 for instance instead of blue & red or in the case of many VAG vehicles orange with brown tracer and orange with black trader. The interference in the trade wouldn't be because it is bluetooth and is normal in most instances. Completely clean switching is very difficult to achieve. Enjoyed watching. Thank you.

    Great professional video on explaining CAN BUS diagnostic. You must be so busy that you may not have time to respond but I have a question. My 07 Infiniti M35 won't start. After a can diagnostic, it shows low to no communication between the modules. The CAN Diag result specifies: open circuit on the CAN L of the DLC branch line but sometimes it says short circuit instead of open circuit too so im confused. Not sure if the modules entered fail safe mode due to that or if they are all fried. The wiring of the car is big and hidden by things that dont allow to test directly at the CAN L wire. Question 1: can I trust this result? Can a bad ground trigger this diagnostic? Can a lose battery ground cause this? Your info says 60ohm at pin 6 and 14 if all modules are connected but 120ohm if a module is disconnected and you said if all module connected but still does not read 60ohms then there must be an open / short circuit (hope i got this right) Question 3: is this info specific to the car you are working on or is it general to all cars? Question 2: I have access to all the modules on my CAN except the TCM that is inside the transmission. Question: Any insight on how I should go about this? Your input will be very much appreciated. Thank you
