DLC Quick Testing Tips 

A lot of good info in such a short video. Wish all videos on RU-vid 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. 👌🏼👌🏼👌🏼👌🏼

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!!

Great presentation and exactly what I was looking for. Thanks!

Very simple and well explained,great video!!

Great job. Now to write thing down to keep it at my finger tips. Thanks Brian ❤️

Good practical demo of dlc data, what to expect and how to obtain the correct readings. 5 🌟 for easy to do.

Nice job, glad to see you making some new content.

Very helpful explanations. Thank you for making this.

Thanks for sharing your knowledge and experties! Was very helpful to me.

Great job . this is exactly what i was looking for

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.

Very well explained. Thank you. From South Africa

Brilliant summary, very clear explanations.

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

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.

Priceless info. Thank you very much.

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.

Quick easy and to the point great found out the truck DLC connector was not the issue it was my scanner.

I am impressed. I grabbed it. thanks very much and God bless your efforts.

Excellent explanation. Thanks

Bonus points for U.S. and Gadsden flags. Thank you for good info and clear instructions

Great stuff Brian!

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.

Nice clear tutorial. Thanks!

Just subscribed thankyou very much I was always confused how to use the ohmmeter Everyone else assumes you know THANKS

Love this video!

Great job 👏 and Good work easily understand thank you ☺️

This was a great video learned alot

Great explanation and demonstrations

Great video, great instructor and tutorials, but I want of your videos. 👍🏽

very correct and nicely done!

Great video. Amazing background.

Nice content. Thank you

THANKS FOR YOUR TIME TRULY APPRECIATE IT .

Thank You for the video!

I watch a lot of video but I never understood we learn quickly with you ,we waiting more videos to learn electrical

Great video

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

Very helpful video sir

Thank you for the video. I wish I had seen it before I ordered a breakout box.

Thanks for that its the first I've seen

Great video,

GREAT VIDEO DEMO ON THE OBD2 THANKS

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.

Nice mine , frumos, inteligență, thank You mann, mulțumesc...from România.

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.

great video

Nice vídeo!!! It's what i needed since my elm obd2 isn't connected to my scanner. Regards from Argentina

Great video!

thankyou 4 sharing. good info

شكرآ لك أخي هذا الدرس مفيد جدا الله يحفظك

PERFECT!! THANKS!!!

timeless. alot if info had to watch it many times

German line vehicles have had gateway modules for quite some time, domestics just started adding them

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!!

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.

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

Thanks for that good video

A lot thank teacher new subscribes Good explain

Man... Very detailed... You are teaching class 👍 Now... Let's talk about PATS!!!

exellent video!!! one think how to find out what color going to which pin???

It was good, i am going out right now for practise. Thx

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

Nice information

very easy to understand video. can you do one on the K & L lines

Good job

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.

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.

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

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.

Easy information For can high and low

very helpful

wow this is great information. thank you. and do you know if Prius is....and as I was writing this you answered. thanks again.

Nice bro
