will this test work on any vehicle and thanks for the great video
@SimplyDiagnostics

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
@SimplyDiagnostics
@SimplyDiagnostics 5 лет назад
Meter is ok for quick checks, go -no go tests, anything more in depth and the scope is your friend 👍

I've had to deal with a CAN problem with my own vehicle. I used the Pico Scope, BUT, I could have used the DMM like your video had shown. Thank you for showing that. With all the training I've had, CAN was VERY LIMITED! You're video makes it look easy.

@neeniebob1
@neeniebob1 6 лет назад
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.

The fact that while measuring resistance of the network , shorting it to power or ground (earth) didn’t change the readings… I guess this proves that simply measuring the resistance of the network is only part of the diagnostic procedure… I need more training in this .. great video sir 👍
