TECH TIP CAN BUS DIAGNOSTICS

Thats the best description ive ever seen even chrysler training didnt cover that way

Chrysler is good for mounting critical components in the worst areas, like PCM's in wheel wells ect. and wonder why they have problems. Great find. Thanks for sharing.

As fellow mechanic but I am heavy and construction. For my knowledge of automotive, you seem very humble and proficient at checking everything. Most mechanics bad mechanics order parts as soon as the isolated the issue. A 2 dollar fix or less all day!

Seriously bro! I think you're a genius! I mean it from the bottom of my heart thank you so much for your videos! I worked on cars before computers and I am learning new things everyday!! THANK YOU FOR HELPING AN OLD DOG LEARN NEW TRICKS! GOD BLESS YOUR SHOP AND FAMILY BRO!! ♧♧

CANbus is essentially a balanced signal line, and the zero volt point is virtual ground, so that mirroring explanation is perfect, when either side does something non symmetrical it indicates an imbalance, it's not the only way CANbus can fail, but it's still a great troubleshooting technique. One of the reasons CANbus was adopted for vehicle data communication is because of the immunity to interference with cheap un screened signal lines, only possible because of the balanced system they use. Any interference or noise with reference to ground is effectively self cancelling. Thanks again for another great video.

Somehow, finally, I seem to be getting to a first base of understanding how these systems work. Thanks for starting at the beginning, advanced channels assume viewers already have fundamentals. I am particularly impressed you were able to find a bad wire! Lesser men would have replaced the end device, and then hunted further when the problem continued. With a bad connection, you might not see a problem until the vehicle was moving on a bumpy road.

Great video, not too many videos show the whole process from diagnosis to fix. I've got some sort of CAN errors and voltage comparison failure I'm trying to figure out and really appreciate this.

Nice diag, very insightful and great explanation of entire problem and solution, thank you .

im just learning canbus, you explained it very simple thanks

This guy knows his stuff.. Kindly like and sub. Show support.. This are the kinda people we should encouraged

🙌 teacher in all your videos you break things down thorough.

excellent video short concise and organized. easy to follow what you did and you didnt overload the audience with gobs of informantion not pertinent to this issue. spot on insertion of the pinout of the dlc and what you were going to measure. no wasted extraneous inof about the dlc. typos oh well

I watch this video and unfortunately I didn't get the information that I need to fix my truck but on the plus side another vehicle I am having issues with I was able to address the situation with this video so long story short I didn't find what I was looking for but you helped with a different problem thank you for that

When the bias voltage raises as shown in the glitch, you would want to verify the grounds of the module that's causing the failure. Nice video. A lower time base for detail can also be necessary in some diagnostics

Thanks, Very nice and informative video. This is also a well built car. That splice is very handy. I'm facing a similar problem on an AUDI. CAN wires there are all twisted together like my grandfather electrician was used to do. impossible to disconnect without scissors... what a pain. :)

Great video diagnosis, why would these idiots give a thumbs down. I liked that you followed up with the fix with visual. You just got a new subscribe.

Great video. You were smart to provide both the diagnosis and successful repair. Thanks for sharing.

Really a great 'down to the basics' of CAN and an easy guide to accessing it. Thanks you !!!

Bro I am very happy because1st time you came on live I like it and thanks your buddy oZ mechanic love you bros

Great video. My only suggestion is use the ground lead off your power probe and when you can keep the vantage pro but pick up a vantage ultra. Watching Can bus on a vantage ultra is great alot of detail. For fun I use my vantage ultra with my break box on my 2017 and drive around and watch data.
