EASY FIX - OBD II data port has no power

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

will a scanner work if you can't start the vehicle?

I drive a dodge 1999 it will read for a little bit then the dash will say no bus then my scanner tool will only turn on when my key is off not turned on. What could this be?

I have a 2008 Grand Cherokee Laredo and someone tried to bridge a pin in the obd plug and it arced and now I have no power to it I checked all the fuses and they are all good and I checked the wired and still no power to it

Question: my port works, but only if it is push down when plugged in. I can plug in, nothing will happen, I apply a small pressure downwards, it works. Fuse is fine.
Any ideas?

I thought I may have seen a yeti or least something furry in the window. I thought it was just a tree 🌲limb at first but it wasn’t:( at about two minutes and 45 seconds great videos just the same cause I have no power on pin 16 good refresher course for me I’m on it👍Thank you.

I have an 04 g35, don’t have a multimeter but the obd2 port pins seem to be in good shape and I can’t find info on a fuse it would be linked to

If i wouldnt have found this they would have deadlisted my truck and i cant do my job without ol ellis.

Thank you you just saved my fedex truck 😊

2015 ford transit motorhome only 1v at pin 16

Mine has 2, 4, 5, 6 & 9 only. My scanner isn’t turning on.

Thanks my brother.., 08 corvette liter fuse caused my odb2 port not to communicate

Thanks a lot , it was very helpfull

What if the fuses are working but still not getting power?

Good info,,,
Definitely applies to Chrysler 300 2012’

I have a 2000 Ford f250 how many wires should I have on the plug

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

is this the same with obd1?

Trying to program a goddamn key for a 1998 Sebring LXi (coupe) and the instructions said to jump pins 1 and 4. I tried.. and now the OBD2 port is all messed up. Also, the frickin jumpers didn't work either

If wire is broken can you connect to another +

Thank you very much sir!

On my Mazda 5 2010 the obd2 get No contact with the car, and bluetooth/wifi is gone also : when i click on the 'phone-button' on my steri gwheel 'mute' appeares on the screen and No voice from the phone system....?.?

Old school installers always knew the cigarette lighter circuit was 12 VDC constant. So all kinds of installs were powered by the lighter circuit. Fast forward to today where the cig lighter/power outlet is still 12 VDC constant but it is shared with the CAN bus. I have ripped out so many alarms, kill switches, power amps etc that all were spliced into the CAN bus/ lighter circuit. Once repaired and restored to factory wiring, power is restored to OBD II

Thanks. Checked majority fuses, no luck. Pulled obd port no power at 16. Going to play w spaghetti in 95°f Sun. Joy! 2015 MB GLK350 rwd.

For a few hours search and listen YOU @ another YOU the best of all YOU's @ what-a duck tape repair

I have to chase down a burn cigarette lighter wire issue.

Can I straight wire the constant 12V to the battery to get my power and then will it read ?

How do u find the common wire to go off of if ur changing your obd port out..is it always number 16 or what? Thanks

I have 16 pins, all look good.

Steeler ship lol😂😂😂😂😂😂

hi, my obd port isnt bolted in, and is jusr hanging loose. anyway, a wire isnt plugged into the little box , and my ac isnt working. i have a 04 chrysler sebring convertible 2.7 liter. any way i could reconnect it, to get power to my ac?

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!!

Fixing a 2007 rav4 2.4 new battery and alternator the starter isn’t brand new but works so the car does nothing unless I put the diagnostic scanner in the OBDll and then the car cuts on but only if it’s in and runs rough but gives no code? Can you help me if you know

On my 2018 Chevy Colorado, state inspection stated they could not acquire a reading. But I took it to autozone and orileys both came up with a P0014 reading. Truck is running fine but any idea why state inspection could not acquire a reading?

"Now you have to play South Maine Auto" LOL! Love it! ;) Great content and advice! Thank you!

Goon morning I have issues with my OBD I check the wire like u say I check the OBD fuse is good too 😢there a problem to my van n was trying to find out what r the codes

I wanted to ask I got a car from the dealer they have a tracker in the car which is fine but it is causing damage to my car computer because it is plugged directly into my OBD port and makes the readers not work. I don't want to disable it I just want to know if I can move it if that is possible

Just seeing this video.. I just had my transmission replaced, and a week later, my check engine light came on. I took it to auto zone and had them connect it to the code reader. Unfortunately, they said my car is not reading at all.. It use to read before my transmission was replaced. Haven't checked all fuses yet. But my cigarette litghter workes because my charger is plugged into it for my phone. Need help??

Gave you a follow great knowledge and all the nicknames for shit is amazing too

I have this exact problem.

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.

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.

His buddy got the Exploder from the stealership... Luv it...! Found On Road Dead

Thanks for posting

I think what I did wasn't paying attention cross the battery cables now I'm getting know signal car comes on but the windows want go up And down Abs light on ect could use a little advice on this problem thank you

My obd has no power, I have three red #10 fuses that are not working (not blown) I can't figure out why those three only don't have power

The power to my scanner port randomly goes in and out. Any insight?

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 👍😎

I have a 2000 ford explorer XLT and my OBT port is dead. I check for power and it has power coming in all fuses are replaced but not getting anything lines dont seem mess with either

Hi there! Does hooking up a camera to the OBD2 port drain the battery when the car is off?

Cool shit, brother
