I have been a heavy equipment mechanic for 4 years and have had extreme difficulty understanding can bus testing. This video really helped it click in my head. Thank you so much,truly a public service on your part
THAT WAS AN OUTSTANDING DIAGNOSTIC VIDEO BRIAN , NOW JUST CURIOUS DID YOU HAVE ANY CODES OUT OF THE RESTRAINT MODULE WITH THE CAN BUS WIRES JUMPED . THANK YOU AND ALWAYS LOOKING FORWARD TO YOUR VIDEOS !
Excellant video Conan. I mean Brian. Most of the time letting your primal urges out will get you in trouble. However I have found repairing a couple of wires in a controlled area is very therapeutic compared to the damages after the big green guy rears his ugly head and "helps" me with my diagnosis.lol And also time is money!!!!
BRIAN, AWESOME that was really enjoyable to watch and learn and the way you tackled the problem was impressive brotha and hope will see more like this in future videos thank you . cherrrrrrs
As soon as I saw something other than 60 ohms on the high speed I’m thinking broken wire. Cause if it was shorted to each other it’d be 0 ohms between 6 and 14. I just had a 2011 Taurus with a similar situation last week broken can line to pcm. I wanted to break out the scope but didn’t because the flow chart was actually decent.
Brian, this was an awesome video. First enjoyed the fact tha you used the U-scope and the breakout box. Will go through the video again to document what ports on the breakout box are for what and what you should see. Maybe a quick video like this one just explaining the CAN BUSS system in lay mans terms like termination resistors and gateways. Just an overview say on twisted pair wires. Are those wire diagrams proprietary or will they show up on say Mitchel DIYer diagrams which I have for my two vehicles? It was a nice path you layed out for someone like myself for a starting point. Thank you Artie ❤️
Great Video and You Made it look so easy to diagnose, thanks For sharing. Hello from México. Ond question where do You get that osilicope? Amy link or website van You share
Brian, how can I contact you about a similar issue I’m having with my 08 F450 6.4 and all the things I’ve tried in attempt to solve my no communication with PCM issue?
Great video, I think a lot of people would have gone with the engine Ecu after ‘the unplug it test’ Would you always recommend to check the HSCAN + & - at the module plug? Also the scope you are using, what model is that? Great work!
Yes, many may have condemned a module, I was thinking that at first! I did not go into enough detail, but with the pcm unplugged and abs plugged in the pattern was the same, so I was thinking at that point common grounds and powers to both modules, then I was thinking, duh , common CAN, so that is why I checked the data line to the pcm. I did not check any other wires at the pcm, and I did not check anything at the abs. I do not normally check the CAN signal at the modules, as most times I find bad modules pulling up or down the network, and removing the module ( note singular) the network comes back. At that point I check powers and grounds at the suspect module.
Brian Mann thanks for the reply, do you think you checked the data line due to the 190ohms? Possibly thinking corrosion with the high resistance... 120 ohms and that would of pointed towards a module offline? I really like CAN Diagnostics and would like to learn a lot more
@@GRUSSNewton I checked the line at the dlc because of the 190 ohms and it is super easy, the scope tells a story. I thought we would have a bad module. Fords are different from GM in the way the modules can be disconnected, with out automatically removing all modules after the disconnected one. So that said the strategy will be different. I did not have a need to look at a diagram on this one until I found that both modules need to be disconnected for pattern to be good @ dlc.
Hmm. I've been racking my brain trying to find an issue. I'll check my splices. My truck was flooded and the sides were full of water. My can line is getting a signal with nothing connected 😞
@@BrianMann216 I'll have to repeat the tests but I believe so ... Yes the signal is clean and it's almost 10V pk-pk with everything connected and it's about 5V pk-pk with everything disconnected. I'm assuming it's coming from another network.

It never gets old watching a fighter K.B. and take names on a diagnosis! Thank you for sharing :)
Thanks!!
Brian this video is priceless. Thank you for using the U-scope and breakout box to diagnose this problem. A million thanks to you! Semper Fi, USMC.
Great thorough diagnosis Brian. Thanks for bringing us along.
THAT WAS AN OUTSTANDING DIAGNOSTIC VIDEO BRIAN , NOW JUST CURIOUS DID YOU HAVE ANY CODES OUT OF THE RESTRAINT MODULE WITH THE CAN BUS WIRES JUMPED . THANK YOU AND ALWAYS LOOKING FORWARD TO YOUR VIDEOS !
No codew in the rcm, bcm , pic, and few others had code for lost comm with abs and pcm..
@@BrianMann216 THANK YOU FOR THE REPLY , I GUESS THOSE CODES WERE EVEN BEFORE YOU BYPASSED THAT LENGTH OF CAN BUS CABLING !

Excellent diagnosis 👍
That’s video was awesome!
Thanks for watching.
Yes, thank you I enjoyed that a lot. Very nice editing.
Thanks for letting me know. I am working to get a more polished final product to you guys, takes some work for sure!
Great video! Handheld scope is pretty cool!
Great video. Good find. Very simple video and very detailed. 👍🏽
Nice video! Great explanation
Great catch thank you very much
Excellent video. Thanks for sharing!👍
Great video Brian, You put out some amazing information, thanks for sharing again buddy

I was out if time that evening, waiting for a picture of the corroded / green wires!

Have you seen my dlc quick test video? The information / diagrams here should show up on any service information system.
Great work! New sub here!
Was it still 190 ohms after disconnect PCM/ABS modules ? Great diagnosis by the way
What do you mean you had to get a little barbaric and jumper the wires? That is ole school tried and true testing. Good video.
Lol, I'd rather not cut and just locate the problem, we did not have enough time though. Old school proved we did not need PCM or ABS modules .

Nice !
May I contact you about your hands on training? I love this kind of stuff.

Brian, how can I contact you about a similar issue I’m having with my 08 F450 6.4 and all the things I’ve tried in attempt to solve my no communication with PCM issue?
Hello sir. What is the name of the software on the computer you are using to test the network? Your feedback is more appreciated. Regards.
Ford IDS is the software that performs the network test.
@@BrianMann216 is that just for Ford or that can be applied to different makes of cars with that particular software? Thanks for your feedback.
It will work only with Ford products. It is the OEM / dealer tool.
@@BrianMann216 I got it. Thank you sir very much. Have a great rest of the weekend.
@@neverstoplearning382 let me know if you have other questions. Thanks for watching.
I did not see it in the comments, but was the wire broken under the door seal?
Yes it was

Even with scan tool disconnected? Is signal clean? Probably other modules hooked up somewhere

how much do u charge to set up my plus 3 with wytec tec authority
It’s easy
good morning what web site is it that you use?
I use identifix and all data for service information
What scope is that?
Aes wave u scope
👍👍
