A lot of good info in such a short video. Wish all videos on RUclips were like this. Straight and to the point. No time wasted. Thanks for sharing your knowledge.
OMG plain simple and right to it, I couldn’t figure out a communication problem after watching this vid and testing exactly how you explained found Tcm was at fault. Thank so so so much it was between a couple hundred dollars and thousands of dollars. 👌🏼👌🏼👌🏼👌🏼
ABS Module here. Loose connector.👍
Just another person whom admires your plain and simple instructions. I've watched many and yours fits the bill. TY
Great video. Accurate and comprehensive with no fluff. Thank you for your time.
This is a great video -- most informative tutorial on how to test the DLC (OBD2) port I have found. Thank you for a job very well done!!
Thanks for watching! Dlc testing knowledge can save techs a ton of time.
Quick easy and to the point great found out the truck DLC connector was not the issue it was my scanner.
Very helpful explanations. Thank you for making this.
Wow... I wonder why all the other auto electrical 'gurus' don't show us these tests! You are just so 'on point'... I can't thank you enough for this video, Happy day.
Good practical demo of dlc data, what to expect and how to obtain the correct readings. 5 🌟 for easy to do.
Great job. Now to write thing down to keep it at my finger tips. Thanks Brian ❤️
Great presentation and exactly what I was looking for. Thanks!
Thank you Sir! I just got a 5.7L Hemi on a run stand and it would start but not run. Your tutorial led me straight to a need for a $0.15 resistor that got the CAN Bus working.
Just wondering all your control modules started communicating after that?
Mine has a problem it's reading 120 ohms and can't communicate to my scanner.
Bought a ecm and it still does the same thing.
Very simple and well explained,great video!!
Thanks for sharing your knowledge and experties!
Was very helpful to me.
Priceless info. Thank you very much.
when you reading 2.5 volts, in ether side, (usually in both sides) means that you have a short on your network and you resistance test (with the key off o battery disconnected) will gives you a value of 0.1 or 0.2 ohms. In that particular test you did... reads 60.9 ohms which is alright and the volts on your low side is 2.3 +- 0.1 average and your high side is usually 2.7 +- 0.1 for the total of 5 volts that is why you read 2.639 and 2.343 = 4.943 + lead resistance usually 0.1= 5 volts +- something.
i did one today and literally read on 14 - 1.98 and 6 - 3.01
I was giving approximates. With a scope we could see acrivity. This is just a quick overview
@@BrianMann216 what if I have reading of 30.1 ohms ? .
I used to have more then 250.0 ohms on my toyota 4runner and I found out that my angel sensor causes the problem but after I fix it I have reading of 30.0 or less and sometimes 60.0 ohms .
Very well explained. Thank you. From South Africa
Nice job, glad to see you making some new content.
Great job . this is exactly what i was looking for
Very gd video finally being more helpful to persons wanting to know what we EXPECT to see as far as voltages in testing methods sir thanks chuck
Bonus points for U.S. and Gadsden flags. Thank you for good info and clear instructions
Our pleasure!
great information, and thank you for your service..
Excellent video, just what I needed. Thanks
Great video Brian. I subscribed. Please do more videos on computerized networks. Your explanations are very clear and detailed, which makes for a great learning aid.
I have 1 I am editing now...
@@BrianMann216 Great! Thanks.
Brilliant summary, very clear explanations.
Thank you!
I am impressed. I grabbed it. thanks very much and God bless your efforts.
Very good explanation thank you!
Ohms as high as 72 are acceptable. High resistance in the CAN will be visible with a scope as the sharp edges are rounded off.
Excellent explanation. Thanks
Nice it gives us knowledge about this and thank you for a very clear explanations it helps us a lot
Thank you so much sir
great keep it simple video. i had to watch it many times to get it all...
Great stuff Brian!
KNOWLEDGEABLE HANDS ON AUTO TRAINING
Outstanding tutorial 👌 👏 👍
Thank you very much helpful information video start to finish loved it
From Nick Ayivor from London England UK 🇬🇧
Thank you that was very helpful, awesome explanation
Very helpful, thank you.
Thank you sir, I appreciate your instruction very special .you don't need expensive analyzer to shoot the trouble of can bus.
Just subscribed thankyou very much I was always confused how to use the ohmmeter Everyone else assumes you know THANKS
Great content...love it!
Very useful and very well explained.
Thank you so much
Glad it was helpful!
Great job 👏 and Good work easily understand thank you ☺️
This was a great video learned alot
Excellent! It's crazy how hard it is to find basic troubleshooting info like this. ... now do the rest of vehicle wiring like testing modules and connectors. :) ... Everytime I try to find info, it's some guy with a scope doing an hour long speech about looking for uneven signals.
Now I see you have a few other vids about testing those things. BTW I'm not anti-scope, just a DIYer that doesn't have one.
I love electrical testing. Many times a multimeter is just fine, however the more I use a scope the more detail I see and can "see" more Cleary what is going on.
Beautiful job and informative
Thank you!
Thank you very much for your trining video is excellent sir
Information like this is invaluable. Thanks for putting this out there! I'm glad I found your channel. If you ever find yourself in South Florida let me know.
An exelent. Information..thanks
Yep
Free lunch when in Syracuse. Just shoot me a RUclips comment. I've had a terrible theftlock issue on the Cadillac cts and all videos on RUclips are wrong saying it's the computer. I've got low voltage 9.3 v between 5-16. But good voltage 12.9 v across 4-16. I now have a direction to go
Great video, great instructor and tutorials, but I want of your videos. 👍🏽
Love this video!
Nice clear tutorial. Thanks!
great teacher,thank you,
great video and it's priceless information i can't find the words to thank you
I am glad to be able to help. What other automotive electrical subjects interest you?
@@BrianMann216 thank you sir for your reply. i am new to learn the waveform of any sensor
THANKS FOR YOUR TIME TRULY APPRECIATE IT .
very correct and nicely done!
awesome, thank you for sharing your time and knowledge
I remember working on a 81 caprice that had the same connector. Had to jump the wire for a blinking check engine light. Thats how we got the codes. And before that we had no stinking codes. I love em both. Like a big greasey puzzle. 35 yrs as a hobby.. lots of fun cars.
Yeah that was a 12 pin a and b
Loved the video, and I did a few screen shots by pressing the windows key and the shift key plus the S key. I had to Subscribe and like the video, so thank you for sharing this information.
Thank You for the video!
Great explanation and demonstrations
Man... Very detailed... You are teaching class 👍 Now... Let's talk about PATS!!!
What specifically do u want to know abour.?
Great information 👍
Thank you sir. This video is very help full for me.
Great video. Amazing background.
Brian great video. I am so glad you're back making videos
Thanks Greg.. will be making more stay tuned!
Great video,
Thank you for the video. I wish I had seen it before I ordered a breakout box.
Break out box is good! Saves possible damage to dlc pins when probing. Also makes easy scope hook up, you will be glad you have it.
I watch a lot of video but I never understood we learn quickly with you ,we waiting more videos to learn electrical
Very helpful video sir
Great Video was able to solve issue that I had.
thankyou 4 sharing. good info
Nice content. Thank you
Great video
German line vehicles have had gateway modules for quite some time, domestics just started adding them
شكرآ لك أخي هذا الدرس مفيد جدا الله يحفظك
Great video!
Thank You!
Some manufacturers require the battery to be disconnected entirely to get an accurate ohms reading, on a Nissan Titan I got burned thinking the network was shorted together just to realize that in the service information I blew past “Remove negative battery terminal”. After I did that I got my 60Ohm reading
Thanks for commenting, this is sure to help others!
Excellent video, sir! Thank you. Thumbs up to let RUclips know it is very good!
Thank you for doing this video i am fixing my 2006 malibu myself and was getting a no communication to my pcm pins 6 and 14 is reading 76.5 ohm
Thank you to help me to know about can bus
A lot thank teacher new subscribes
Good explain
GREAT VIDEO DEMO ON THE OBD2 THANKS
Nice mine , frumos, inteligență, thank You mann, mulțumesc...from România.
Hi Brian, all tests check good, except 4 and 5, could only get a reading with key on engine off of 1mv, thanks for the Instruction videos Great!!
Thanks for that good video
It was good, i am going out right now for practise. Thx
Please show us the results!!!
@@LuisMartinez-fr9gq my Car was OBDI compliant, not OBDII. But your video was very helpful. I thought long time ago that the port was broken. It wasn't. Just OBDI type. Thx
I am not the one who made the video, but thanks for replying, i was reading the section of comments, my car has an OBD II program so yes totally different, i have an issue my car does not start, only cranks, but at the same time my scanner will not connect to ECU, i want to check the pins Brian was explaining but my port OBD do not have pin 6 only pin 14 for CAN BUS. by the way i have a 2001 Hyundai Santa Fe 2.4, comes with 7 wires, 4 at the top and 3 at the bottom, do you know how can I get the info of each pin on my OBD II port.
exellent video!!! one think how to find out what color going to which pin???
great video
Thanks for that its the first I've seen
Nice vídeo!!! It's what i needed since my elm obd2 isn't connected to my scanner. Regards from Argentina
timeless. alot if info had to watch it many times
Thanks for this info... I have a Seat Cordoba 6k2 2002 1.4 16v, and the problem is that wen i plugged it the scan tool the hole car resets (power off then on for a split second) also, the engine runs like crap a few hour's before it recover is self.... It's like it's going to protect mod or someting.. The connection gets lost as we'll... It's hard some times to even delete the errors... I'll try this test you showed us, maybe I'll find the problem... Thanks again
PERFECT!! THANKS!!!
Very nice video man. I have the following problem on my wrx from 2006. On key position 1 and 2 the obd port has power. When I turn the key on the last position the power on the OBD shuts off . When I hang my delfi diagnostic box on the obd port it also indicates on position 1 and 2 that it has power, but can´t connect to it.
What could that be for a reason? The cigarette lighter has power on all key positions. Would be so thankful if you have any tipp to give.
Kind regards.
i watch all along as a reminder
Americans! always thorough and to the point. Great upload Brian. I liked it. I like the American Flag on the back wall. Americans do the job right because they are practical. Thank you. I would like to know what is the purpose of pin 8, what if we jumper pin 4 (Ch. Grnd) to pin 8? Could you please share your expertise with this. I heard it is for some GM Vehicle that does not show the option to " Remote Key Learning" in the programming menu on Dashboard. Keep up the good work. Appreciation from Canada.
Nice information
very easy to understand video. can you do one on the K & L lines
Maybe sometime, they are more of a standard single line, not as much fun as CAN lol
Easy information For can high and low
Hi Brian thanks fore the greate video's ! I have a problem on my bmw 630i 2005 model , i exadently put 12v on the litle yellow and black whire 😔 of the canbus cables i that is was a tweetercable.. after i did it the car won t start !! I disconect the battery, pull al the relais out ,check the fuses and it seems fine , can you please tell me why it won t start .. and when ik put the computer in the OBD it make s no connection .. 😏 what do you think ? Thanks
Great video Brian. Any idea how to find out which modules house the termination resistors when the Computer Data Link wiring diagram does not show where the resistors are ? 2007 Ford Ranger. Thank You.
Many times deep in the service information , sometimes description and operation of data bus they will tell you.
Good job
This is very well explained. Now in my 2007 Mazda cx7 everything is good according to your explanation to have a good can bus, good Battery voltage, good ground, good ohms reading between pin 6 and 14, and still my scanner can't connect to the computer to check for codes. Any idea, suggestion? I was able but to connect one out of 5 tries, and eventually ones out of 10 tries in a period of time of 6 month to a year and this year I was able to connect to the computer few times during the year to check for codes and now I am NOT able to connect at all. Any suggestion will be appreciate it. Just recently I did replace the obd2 connector, to eliminate the possibility of a bad Obd2 connector. Still I can't connect to computer.
