You just saved me so much money. Dealership was going to charge 250 for diagnostics and 2700 for repair. Thank you a million times

[stephenwarrener]

Thank you! Local Mineke charged me $200 and couldn't diagnose the problem and then they wanted $950 for further diagnostics! I resolved the issue in 10 minutes after watching your video.

Good info. One thing to add. If there is no voltage reading, you may be able to isolate the issue further. You could put the voltmeter negative lead on the battery negative or chassis ground somewhere to see if there is voltage when the voltmeter positive lead is on pin 16. If there is, you would know that the issue would be the ground wire in the connector on pin 4. and not a fuse issue. Likewise, you could put the voltmeter positive lead on the battery positive and measure with the negative lead to pin 4, which would indicate the issue would be the wire in the connector pin 16, or the supplying fuse. Of course, there is a chance that both wires are bad!!

Yup, lighter fuse on my 2005 gmc was blown. Scanner now works again!!! Thanks for putting this video out.

[tonystanton]

Had no power to the port and was pulling my hair out looking to find out why, saw this video, may share a fuse with other acc you say, like the cigar lighter you say, my cigar lighter doesnt work, checked the fuse and replaced the blown one, i now have power at the port to do my scan, 10/10 for this video man, thanks heaps 👍😎

So glad I found this video before I went under the dash searching for a loose connection or broken wire! I just bought a $40 OBDII scan tool and the vehicle I needed it for showed NOTHING when I plugged in the brand new scanner. I verified the tools function on another car and it worked perfectly so I knew someone out there had the scoop on this likely common headscratcher. Thanks for saving my back and my time. It was the Cigar fuse under the hood that when replaced, energized the OBDII port and a simple fix!

2003 MDX - VSA reset the iterwebs tells you to jump pin 4 and 9, I did that and the jumper cable turned glowing red hot. I pulled it part, and after that the car wouldn't start and the OBDII code reader was dead too. I found your video, found the fuse that I just blew and fixed it up thanks to you. Any idea why my fuse blew, the other video has 100's of people commenting that procedure worked for them. Me, not so much. Thanks man, you're a lifesaver!

Thanks for Video. I was able to pass my failed emissions test do to "no power" to the OBD connector. I also avoided having to pay 167 dollars for a diagnostic fee at the local shop. The problem was a blown 10a fuse in the "Room LP" slot. I never would have found it without your video.

Thanks for the tip! 2005 GMC Van - 15 amp lighter fuse

Very informative video. As suggested in this tutorial, my make/model did NOT indicate either in the manual or thumbing through many websites which specific fuse powered the OBD. I then turned to A.I. (open AI) and asked it to find the information specifically for my make/model. It provided an informative answer. So, if all else fails, you may try that method to identify the blown fuse.

[richardwasserman]

Thanks. This gives me a starting point on my project van.

[nolannyr]

Dude you are the man. Thanks! the car in my warehouse had this exact issue, the fuse ended up being on the engine bay panel but it was def there and had popped. easy replacement and saved me money from getting ripped off at the mechanic/dealership.

[ednamiller]

Thanks so much - my 88 year old husband (who is by no means mechanically adept) just got the "answer" he was looking for from you while trying to repair our 2003 Saturn.

Thanks a lot man.
Through your video, I discovered the problem with my OBD2 Port.

[mikemike]

Thanks bud. Great video. Made it super easy.

[KariCurry-fylq]

I love how through you are so very helpful.thank you

[thecapothedon]

Man I been looking for this video!! Thank you!!

D&E, The one day old new battery negative connector melted leaving craters by the healthy still post and the starter was smoking, at the moment I stopped the car and lifted the hood, due to so much fumes coming out from under. Can I connect to the previous battery a portable power pack 12V Centech just to see if the OBDII scanner will bring some light in whatever happened or I would do much worse by doing that? Regards from FL.

Hi from AK just came across your video. Im now subscribed . Great help, appreciate you and along with helping me figure something out you actually made me laugh and I needed that. You are funny. Thank you for that.

[islandgurl]
