will this test work on any vehicle and thanks for the great video
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
Meter is ok for quick checks, go -no go tests, anything more in depth and the scope is your friend 👍
@@SimplyDiagnostics How do you know if the car has CAN at DLC im trying to work on a 2018 volkswagen beetle
Was great
When I measure resistance between 6and 14 it shows 46 ohms what can cause it?
Thanks
Have come across you’re channel from you visiting the boys in NY. I am Up in Canada and love how this CZcams brings all people like us gear heads together 👍🏻
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.
Thanks! Learning all I can about CAN This video was a great help.
I like how you manufacture the faults to definitely show what happens. Nice approach.
From Orlando. Thinking about getting a Pico for personal use on my diesel truck and wife's suv. I think that you did a great job of explaining the what, and why. I really appreciate your time and efforts. Best wishes!
The best video yet. No "BS" like the scam mechanics, they don't want you to know this, so they lead you down a rabbit hole, low life's. Especially the dealerships, and those who sale those shorted out ECMs. You are a hero to many!!!
Hi Steve
An excellent demonstration - clear & concise.
A similar demonstration for the K-line would be much appreciated.
Yes two CAN videos today. Good video. Been waiting for CAN VIDEO so long. Thank you
Haroon Khan you’re very welcome, enjoy 😊 Steve
What a brilliant video! I've always been a bit scared of auto electrics, but I feel much more confident. Great presentation skills, keeping the subject accessible. New subscriber. Thanks
Great and clear explanation in less of 30 minutes!
Great video! I always recommend my techs to hook up our scope on good working vehicles to familiarize our self’s with healthy wave forms to allow us identity issues when the fun jobs come in. Thanks
Great demonstration Steve with clear and concise explanation. Also good to see the correlation between the DVOM and scope. Keep up the good work! 😀👍
Many thanks Terry 😁
Best can video I have seen for easy understanding, thanks
Thanks for your time, this helps out alot starting to see more problems with these systems.
Excellent video! Please do more in this series. Thank you.
Great video you made it so simple more me to understand. Hope you will continue with the rest of the communication networks.
Great video man. You really broke it down to make it seem easy as cake. Definitely took a lot of mystery out of CAN diagnosis.
The Yota Tech many thanks, really glad you enjoyed it 😁
Thanks Steve, Very informative, I learned heaps from this one short video...You're Awesome.🤗👍🇦🇺
Nice 101! Thank you for sharing!
You did a great job on reading CAN signals!!! Been watching other videos not making much sense. You should be an instructor!!! You made very simple to understand.
This is really a great video. I've never seen a video truly explain so clearly how to test and understand the CAN network. Hope you put out more videos on the topic. Can you explain the terminating resistor functions? Here them mentioned but never explained. Great video. Artie 👍
Thanks. You have explained perfectly for me. I don’t have a scope so I was really interested in the dmm results.
Great video Steve and nice touch with the DVOM and scope while disconnecting terminating resistor modules and short to grd & voltage. Keep the videos coming!
Hayward's Automotive really glad you liked it. I tried to keep this one real world and useful, not just for the scope jockeys 👍
super cool to see these different scenarios on the scope ..... meter work around also great .... thank you !
Excellent Steve. Very well explained. I do a lot of Mobile diagnostic work but occassionally I get a canbus issue which causes me problems. Now, thanks to you, PROBLEMS SOLVED !! :-) Keep up the good work. :-)
Thanks for making this lesson simple I can now understand can keep posting videos and keep everything simple
That is one fine setup!
Thanks, its a big thumbs up from me. Great video and set up.Still getting to know CAN. This helps a lot
a very good example of can communication. thanks, sir, great video
Naushad Ali glad you enjoyed it 😁
Great video Steve! Very hot topic for a lot of technicians. Can't wait for more 😁 Thx! 👍
Thanks Dylan 👍
Brilliant Steve and thank you.
great explanation. very helpful. keep up the great work amigo!
Top video Steve thanks for taking the time mate
Chris Brown you’re welcome mate, glad you enjoyed it 👍
Steve what a great video training tool thank you sir. keep making em!!!
Great Video! Explained Well.
Excelent tutorial! Thank you!
Really good explaination. Thanks for the video.
I have engine service malfunction on the dash, 2013 fiesta, came on today. No codes, runs great otherwise, so tomorrow I'm checking around. You explained CAN very good. I don't have break out box but I still can check for 60 ohms with meter and eliminate CAN system. Thank You Eddie p
Very nice video man! Thank you for sharing this.
Thanks for your time! Learnt a lot!
Excellent informative video, thanks for taking the time ;-)
Steve u make it easy to follow compare to other people on you tube grate tutorial keep up good work buddy u first i have subscribed too thanx
sir you have a great video, pls continue what you're doing. have a great day.
I just saw you on WUW with Eric O on the South Main Auto Channel. Very entertaining and fun. First time on your channel. Good Video and Camera work. Good instruction and tips on CAN Lines. As Arnold would say....."I'll be back!"
Absolutely awesome and rare info thankyou very much and many notes written down.
Great explanation in simple English
Top Video, very good Demo, Thanks Steve.
Great vid that 👍 Unsure how it’s taken me so long to come across it!
Bloody enjoyed it,for years I have avoided electronic repairs,came across Eric’s channel,then yours,and guess what,after all these years of saying no ,to compcated ,I’m am interested,enjoying,don’t jump to conclusions,prove the fault,9 out of 10 it’s a wire ,big big thanks,keep it up,ps I bought a fiat basket case,so I could put it back together,to diagnose the 1st problem, and I have green crusty on back fuse11.many many thanks,
HI Sarah. Once you know there is a fault, how do you identify the wire or pinpoint its defect location? Any tips?
Steve, great video, Bosch invented can so nice to see Bosch scope!!
Excellent teaching keep up with good work :)
Excellent how to video.
Superb, and very well demonstrated.
Thanks Jools, glad you enjoyed it 👍
awesome i find your videos very enlightening and informative thank you
good info and great test!!!!
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.
neeniebob1 exactly 👍 this is the entry level video for a series. Just enough info to whet folks appetite for the topic 👍 glad you enjoyed the video 😁

Hahaha. That actually mean something like: Glad you enjoy digging a hole
with spade... Hvala tebi što si me nasmejao :)
nemanja dzombic oops, I guess google translate isn’t that good then 😂
Birds chirping with a Snapon DVM and Bosch oscilloscope and a Pico breakout box... Man that is heaven👍👍
Outstanding job
Awesome thanks
Great video
Great vid some good info there clearly explained
Thanks very much great explanation
thanks for the great video
Great Job
Well done Steve
passman85 many thanks 👍
Cheers Steve for excellent can training, I now name this day CAN SUNDAY after you and diagnose Dan's videos! Cheers my friend, Sandy
sandy anderson awesome 👍
Nice video! Love the dog in the background :-)
Great vid Steve 👍
Vdubs 60 thanks pal 👍
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 👍
Hi, great video.
Thanks for this great video. I see people troubleshooting the CAN network but never a good working system and starting from A to Z.
Jim Nicholson
Good video the breakout box makes it very organized. If I am careful, I can take notes on the measurements on paper and find my link error on 2003 Hyundai Santa Fe.
Thanks alot for taking the time to make this video
Pretty straight forward and easy to understand
Good job please Keep ’em coming !
Excellent video......
Great video thanks !!!
Great vid✌🏼
perfect video
Well done some mysteries solved.
GREAT VIDEO , JUST CURIOUS CAN YOU HELP WITH DIAGNOSTIC QUESTIONS AND GOOD TO SEE YOUR VIDEOS EXPLAINED IN DETAIL . I HAVE A FEW QUESTIONS BUT THAT WILL BE FOR A LATER TIME IF YOU ALLOW PLEASE KEEP UP THE GOOD WORK AND THANKS SO MUCH FOR TAKING YOUR TIME TO MAKE THESE VIDEOS .
8power0 join the Facebook group (links in the description) and ask away. I also have a Tech support service if you look at my page. 👍
I enjoyed that video that demonstrated clearly, things in the real world don't always agree with what's written.
Very very interesting
Thank you !
