A lot of good info in such a short video. Wish all videos on YouTube 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

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.

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!!

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.

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

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

[themechanicreviews]

Great job . this is exactly what i was looking for

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.
