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!
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.
This is exactly the same principle as that used with networking computers using ethernet cable. In computing it's referred to as UTP - unshielded twisted pair 😊
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!! ♧♧
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.
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
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.
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. :)
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
Hi, thanks for this bro. Just had this happen to me a year ago when I replaced my ATF on Subaru legacy Er HC on the dash and the dreaded Christmas tree, just left it overnight with battery removed and it hasn't acted up since. Just bought a scantool(the Ancel X6 and saw the diagnosis codes B0202 CAN-HS bus off, B0221, CAN-HS ECM no-receive data, B0222 CAN-HS TCM no-receive data) and researched them, I was wondering what caused it for a year, just arrived at the answer thanks to your video by putting 2&2 together. Keep it up bro.
Very good video as im trying to learn this stuff. Have 2016 terrain 2.4 liter with u152d-00 code for lin bus 2 lost communication with device 13. Trans went into neutral and wont go into park or any gears. Of course there isnt shit on internet of my knowledge to figure it out. Now just saving for decent bidirectional scan tool to help cause people where im at not to be trusted fixing my cars.
Nice job. Good find. One thing tho. Back probe pins are called that for a reason. They go in the rear of connector's. The next time someone scans that vehicle they may have proplems.
For that system they have an OBD2 pass thru socket box with the identifications so you use banana plugs to access signal. But in defense of his pin tap in front those pins are so thin they usually fall out.
@@carmo9693No, thin maybe, did not see them fall out. Those pins are round in a rectangular terminal. Maybe not today but if everyone used this practice we will start to see obd connection issues that will prolong the diag for the main issue at hand.
Thanks!! I appreciate you helping us figure out CAN stuff. As a home mechanic, this is that VooDoo secret the dealers kept to themselves. Oh no, you can't figure this out. Only we with the knowledge can fix it. Anyone have a recomendation for an inexpensive scope for us Shade tree guys?
Pico scope has a 1 channel hand held scope for about three hundred + or try to look for a used vantage pro from snap on , those are really good beginner tool , it's got presets setting.
Scanner Danner also on learning wave forms.

You do a great job explaining all this, broke it down to laymen's terms easily understood. You have a new subscriber, i could learn from this channel. BTW, could a oscilloscope be used to test the can bus?... and does OBD2 port use those same two pins on all cars for testing the can bus?... I do assume it would.
Yes the Automotive Oscilloscope is used on all OBD 2 Cars and Trucks. Pins 6 and 14 are Can High and Can Low. If Eric used a Break out Box, testing the CAN Network would be much easier for him.
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
Great video really like the information but you can change the time base and you can change the trigger put it on single sweep and it might capture the glitch easier
I have a NO BUS message on my 2016 Dodge charger pursuit will this procedure work to diagnose my problem as well or is it something totally different? traction control, ABS light triggered.. please help if you can
Good video, but for people that are interested in performing this kind of work, you shouldn't stick backprobe pins directly into the dlc. You could potentially cause damage. It's much better to use an obd 2 breakout box to perform this kind of diagnosis. It's a safer way to do it, as far as preventing damage to the dlc, and will also provide a better connection than backprobe pins will.
My 07 jeep commander has set a "lost signal" code for every module the bcm controls. I havent started diagnosing it yet, but, i think the place to star is checking grounds and the harness. Ive seen wire looms resting against coolant hoses and what not.
very good video. thank you. i have a question-when you pull the single wire connector off the splice pack-is it can hi or can lo? i know that they rely on twisted pairs. i am just getting into can communication diagnoses and am still a bit confused.
Any ideas,,,, have a customer trucks. 2013 ram 1500. Did head gaskets on the truck. Have everything hooked back up. Hook the battery up. The key does nothing when you turn to the on position. No dash lights, nothing. Battery at 12.3 volts. Can check codes. So started unplugging each connect at the can splice section. Came to the ecu splice, and all the dash lights pop on radio, fuel pump. Try and crank the motor, doesn't turn over. Plug in the ecu splice and you can see for a couple seconds on the dash says no bus, unplug the ecu splice then it all works. So this really sucks to have the ecu the problem. Any ideas of things to check?
Thanks man this video is awsome i learn alot, i was following diagrams on shop key, to understand a little more. Ur awsome do you a book to know more about car electronics?
Thanks for instruction. do you know how many can bus are in chrysler 200 2016? i found just one rear left side of driver seat. also what to do if my scanners can not recognize any data from the obd2? Best
I have a 2006 3.5 Charger that dies after it idles down to 700 or so rpm. The code is lost communication with T C M. I HAVE A NAG1 transmission the dealership said replace the ECM. Is this correct or could it be a loose wire. 211,000 miles
Hi, Nice explanation. I have a 2007 Gl450 and there is no audio/sound from the radio/cd. The command turns on fine and appears to be running fine both on radio and cd but there is no sound from any of the speakers. Before there would be sound for about a min when starting in the morning and then nothing. Now there isn't any sound at all. I pulled almost every module in the car and opened it up to check for water damage--none found anywhere. Only one fault code: "incorrect can message from control unit n80" which is the steering control module. I replaced the clockspring and the module above the clockspring with OEM units from the dealer. Still there is no sound. I'm guessing the fault might be in a wire or a ground connection somewhere. Any thoughts? Where can I get the wiring diagram for the CAN bus for this car? Thank you.
So can a ob2 scanner w live data reader catch cunbus issues? Can the TC conect or getting tc oil on it on a NAG1 tc cause ground or issues w the conbus ? Bc i get static on my radio with the radio OFF on only one spker n the right rear deck only !!! On srt8 charger 2014!! So i am thinking being that tc connector got oil in it from tc overfill ! May b it now messes up that electrical field 13 pin connector signal from the TC,, i also had a one time code u0300 lost communication w the tcm pcu but cleared code and never came back !! Thats when TC had spilled out the oil from overfilling it!!! And now left conector 13 pin tc with oil on it nd i am wondering if that can give CUNBUS any issues? Let me knw wha u think bruh ty
My 2006 dodge Sprinter doesn’t have a pins in the 6 or 14 obd2 but I’m getting no can communication with engine control module codes how would I go about scoping it out any ideas this is the first sprinter I’ve worked on

I have 2004 ram 1500 and the instrument cluster will intermittently fail causing my headlights to come on, no wipers, a/c, no turn signals, etc. How can you diag when there is no signal and/or communication because of no bus where the odometer is? Please help !!

ADVANCE LEVEL AUTO, what scanner can I use to test each CAN module one by one to test and verify its good? Do you disconnect each fuse in the cars fuse box one by one while watching the CAN buss signal to find the bad CAN module? do you use the Fuse box or what to disconnect each module one by one?
Thats the best description ive ever seen even chrysler training didnt cover that way

So i have a short to ground , and at the splice / star connector i read close to 0 volts on my can + / can - , now i want to disconnect the modules till i get my correct values back
Nice techtip thanks greeting from Holland
What's the name of that connector where the bundle of CAN networks are connecting
My 2017 chevy malibu is showing code U0164 ( the can bus failed to communicate with A/C control module..fuse F33 was blown so I replaced it. AND STILL NO POWER to turn the A/C on
Thanks for nice video. I am getting no-comm to abs/esp module. I like to try what you did. Can I keep running the engine while pulling module by one?
ADVANCE LEVEL AUTO, what scanner can I use to test each CAN module one by one to test and verify its good? Do you disconnect each fuse in the cars fuse box one by one while watching the CAN buss signal to find the bad CAN module? do you use the Fuse box or what to disconnect each module one by one?
Great Job! Looking forward to more videos like this.
I got more on the way. Thank you for watching!
