BURNED...by a Buick?? (USB Ports DEAD) 

Answer to your question: recent AC repairs were performed (dash removal) Sitting here eating my bowl of cereal LMAO cause I already knew where the problem was.. GM TECH OUT!!

Previous owner got tired of his girlfriend always playing on her phone, so he killed the USB port. XD

Something to keep in mind in the future… on certain gm models the HMI and radio are updated/programmed through a USB stick. You download the file onto the stick through your laptop using techline, and then insert the stick in the car usb port. The car screen should then ask if you want to update. This process takes forever and fails often. It could be different now, but that was the case 3-4 years ago when I was at the dealer.

A-HA.....the ol' USB SPARK GAP problem !! 🤣🤣🤣🤣

I've had that USB connector unplugged before, several times. It was always after another repair. Those 2016 models were famous for the rear HVAC temp door breaking. Repair involved removing the entire dash board.

“Someone’s been here before.” Don’t be so sure. My brother’s brand new 2022 Bolt EV had no working USB ports. Took a few dealer visits to sort it out too. Unless the dealer did that when performing the battery recall service before the first sale, it was like that from the factory.

As usual, your knowledge of and ability to use documentation proficiently pays off!

Another fine example of sticking to the service data and not to miss anything. I've been around schematics and blueprints so I understand overlooking something. It's difficult when you're banging your head against a wall at a shop with them waiting for a diagnosis. I had to replace the usb port in my new car because someone plugged something in backwards and broke all the pins off the port. They were 50 dollars dealer order part. The dealer wouldn't cover it on their basic warranty like it was some kind of maintenance item. Took me 2 minutes to replace.

Another good lesson, thanks. TSB's can be very helpful, but in the end they're just pattern failures - a potential trap we can all fall into sometimes.

Are you the only guy in the country with the tools and the smarts to diagnose cars. it seems that any “shop” should be equipped and qualified to diagnose. Job security for you.

I would try a known good usb cable plugged into where the blue and green cables under the dash start. If the new cable is good it’s the wiring to the center console. If it acts the same with the new cable then it’s the stereo. Unfortunately Chinese car stereos are known for dying unexpectedly.

That was tricky, an unexpected problem! Well done.

Wow you got burned in that one!! You said there's nothing wrong with power and grounds but you didn't check for continuouity. Wow you got that nailed! But you got it in the end! Lesson learned!! Great job Ivan!!

I appreciate your hard work and your sleuthy ability thank you. Keep up the good work

I can't wait to learn more about this new scanner😊

Awesome diagnosis😊

A set-up ??? Good job rooting out the problem, Ivan. You are the best.

Your Chinese made Buick is broken? No way bro.

Great diagnostic, Ivan! Not an easy issue to follow (brings back memories of my trouble with the USB hub in my PC, that was faulty but acted normal). Certainly some sticky fingers were there testing something in the BCM, and forgot to put everything together. Silly fault but still time consuming.

Great work thanks 😊

Thank you Ivan

Seeing the mini-USB connector on the hub and the working receptacle on hub 2, I'hav plugged in a mini USB cable in usb 2 and powered hub 1 from it. But then you need to have those cables handy of course. I'm only at 5:13 so anxious to see the final verdict 🙂

Thanks for the video Ivan.

Yeah.. why was that connector unplugged >??? Great that you were able to find the problems... Kudos to you.!!

Hey Ivan a good one before the Holiday weekend..Have a Good one!

Nice new tool, I recently went all in on the X431 pad 7 , after 2 weeks i am impressed with the speed and features , my think tool is a great back up . Just wanted to put in a good word for technology

I knew you would get it, Ivan. GREAT VIDEO!

Nice process and find Ivan. Part of diagnostics is a little,bit of burning tires based on flies which may indeed be false flags (tsb in this instance). None the less, reverting back to your methodical process found the issue.

It was unplugged because the car wanted you to come by and say hi .

Yup, we've all been there before. Something new with this video.(HMI) Good one Ivan. Best part. You found it!

thanks for sharing

We've all been there. When deciding on diagnostic strategies we think what is most logical. Sabotage is not one of them.

Ivan when he sees the connector unplugged: 😮🙄🤦‍♂

A comment on these, keep a mini usb cable on you. IF your windows machine detects a USB Hub when you connect the mini usb to the ports/media interface, you can infer that the hub is probably good. (Hub > mini usb > USB A end > Computer) Just don't try to connect the mini cable to the HMI side... it doesn't end well.

Almost like fixing a desktop. Check the power to the wall first.

Nice video Ivan.

I’ve been loving the Thinktool Platinum S10 Pro. The only thing that can be a pain sometimes is carrying around that big ThinkLink J box VCI all of the time. I wonder if I could get the ThinkDiag or ThinkDiag 2 VCI to work with it and use unless I need the bigger one on a certain vehicle.

I thought it was going to be in Valet mode as there was a data pid for that on your scanner. Powers & grounds powers & grounds! oh and make sure its plugged in...👍😄

It happens to everyone. Don't beat yourself up Ivan. Thanks!

Hello Ivan Nice to see you this morning. Thank You

Good morning Ivan 🙏

Good video, you have always had more trouble with the vehicles that someone else has TRIED to fix before and then gave up. I wonder what it was unplugged for in the first place, what problem were they trying to solve?

Something similar happened with my 2019 Buick. But in my case the ports would not recognize the music USB stick I plugged in. They charged my phone but no data. I knew there was a software update to my radio because a couple Buick tech on the message board mentioned it. But the dealer kept telling me there was no update. I gave them the TSB number and they said it didn't apply to my car. Told them I wanted a replacement radio then since mine was defective, still under warranty and not operating as it should, they denied that request and told me there wasn't anything else they could do. I called the Buick customer service number. They offered to send a tech to the shop so I dropped the car off on the specified date. Got a call from the dealer the next day telling me the Buick tech did a software update to the radio, even though the dealer tech swore there were no updates and the USB port module was bad so it was replaced. The USB ports have been working since.

My VW USB was wonky. Fortunately I looked at the connection pins in the USB port first. One pin was bent over. Bent it back and it then worked.

Many people are paranoid about being tracked and they " think" disabling the connection to the SD card (needed for nav maps) prevents onstar or other systems from tracking you and doesn't throw an error code like a check engine. The reality is it doesn't disable onstar or gps. It just doesn't display the nav on screen. Just like a pc, an unpopulated USB port is ok. Having a blank USB extender plugged into a pc port won't be a problem. The pids did show it expected a card reader and the value was zero, but it's not a big deal. Side note: The envision is the only buick on the consumer reports recommended list. I own a 22 Envision Essence ST. Yes there are some minor quirks and annoyances but it's the nicest wheels I've ever owned.

That was a hell of an air gap on that connector!

Congrats on showing the process & how easy it is to go down the wrong path. Question- who now owns the new usb hub?

IVAN, the X233 USB connector was unplugged because when the shit hits the fan it comes in three's as they say. From here on things will be better (or at least look better). Cowboys everywhere🤠🤠🤠🤠 🤠

I've had a similar experience with a 2019 Jeep Grand Cherokee. Someone replaced the dash and forgot to plug in a connector.

Awesome

"Unplug and Play" it's a no go!

I bought a used tundra and after messing around with it noticed a few modules that were installed but had no wiring. Some had wires going to them but not plugged in.. turned out they install the modules at the factory but dont plug them in based on which package the car is supposed to have. Mine said it didnt have any security system or any of the fancy stuff but after buying a infotainment screen turned out just for that 150$ screen i got navigation, security system with remote start, backup cam and sensors, heated seats and the whole package.. dont think they do that with many cars but guess it was easier to install all the stuff for them for whatever reason..

Ahh. The spaghetti of wires....Good job Ivan.

Get yourself some male and female mini USB connectors for those connectors. It will make it easy to see if +5V is present. First thing I would of tested.

Owning a business is difficult, Owning your own f-ups (or those under your command) is also equally difficult. Honesty builds loyalty -- it's alright to jump to conclusions, as long as you don't overshoot and land in the parts can(y)on.

I don't use my truck's USB ports. I drive my vehicles into the ground, so the electronics tend to get behind the times. I installed a 12V auxiliary system powered with a LiFePO4 battery for other reasons, but I use it to power several USB-C PD power supplies that will give me up to 100W each for things like laptops and fast charging my phone. If you were home, one thing you could have tried was feeding it 5V from a power supply to see if at least the charging ports came alive. BTW, those USB-C PD devices take 12-24V in, which makes it very convenient.

that was a good one.

12:54 Ivan says "I really don't know what else to do" 😮 Don't think I've ever heard him say that before

Not uncommon to see that. Some GMs have a shift to park issue where you have to replace the shifter and add a jumper harness, which requires that center console to need to be pulled back. I've personally seen this more than once after that repair.

It came with the new fangled bluetooth USB connections

The ol bt USB charger 😊

1:46 "Nothing wrong with the wiring..." ??????? How did you come to that conclusion so quickly? 2:27 TSB #5 says ".....start inspecting the wiring...." When you showed the wiring diagram, 3:04 , I suspected the K233 & K4. C'mon Ivan, you're better than that. I'm still a subscriber and watch your channel daily. Keep them coming. 😉

Previous owner probably unplugged the X233 Connection to be able to have Car Play & Android Auto Play features 😮

Those silly oscillating progress circles....they get fancier and more numerous every day. Give me back the hour glass. So much fluff in software interface. Geesh.

The radio in my wife’s Honda van is w/o the fuse since we bought it. We were told that the slide door wouldn’t work with the radio fuse in. ???

👍👍

There's a general observation that Chinese are exceptionally detail oriented meaning they generally are conscientious. Chinese leaders can be extremely overbearing resulting in dangerous cut-corners. Oriental students run circles around our U.S. students in college.

Why was X233 unplugged? I believe 2 causes 1 on initial purchase the owner didn't want that "option" at the time so on pre-delivery it was either unplugged or just left alone, 2 owner took to dealer for that issue and the tech or even the service writer wanted to "up sell" more expensive BCM when the returned for the charging port problem!!

Happy 4th of July everyone.

The old bear in the woods scenario.

You are going to see that pile again. There was a reason that it was unplugged. Otherwise, the owner would have had it at the stealership many times prior to you doing the diagnosis.

I wonder if if it kept blowing fuses, or I had a parasitic drain maybe? Very interesting tho

easy said while writing this comment, I know. But always first check cables / wiring ;-) but who wold guess that the USB from the console is not wired directly to the radio ...

It was unplugged so that it will save energy. Lots of energy needs saving so electric vehicles can be charged during heat waves. Buick is an energy saving beast. Want to save more, unplug more stuff.

I bought a 09 Impreza a few years ago. Driver’s power door lock didn’t work and fresh air to recirculate blend door wasn’t working. Both were just unplugged. What the???? Why??? Who knows. Plugged them in and they have worked fine ever since.

Feature removed for American market??

👍

human machine sounds like something out a sci fi movie maybe said i will be back thats why its unplugged

Have you tried turning it off and on again? Are you sure it's plugged in??

Perhaps the previous owner had unplugged it because the port was not working and had intended to replace it but never did when they sold it. And like most people when selling a car you either forget or don't care because it's just a minor problem.

Ivan I have a quick question , my Toyota had a code P0442 ( small evap leak code ) I checked my gas cap seal and it was cracked... I bought a new seal cap and deleted the code ( 3 days ago )... I scanned it yesterday and drive circle it's complete and all monitors are green , that's a fix right? Ty for sharing your knowledge with us

My thoughts exactly. Someone took the time for some reason to unplug it🤔

It will happen to everyone, anytime, any reason, anywhere. I have come to the conclusion that it doesn't just happen to me. That's all that makes me feel better about it.

Why would you risk plugging your expensive phone into a suspect port device?

Unbelievable

Hi Ivan Venezuela

No Parts Required!

It starts to get a bit hot & smokey after a while.

Wiring diagrams to the rescue.

I was wondering why you weren't checking wire continuity.. It was the only thing left.. other than a cooked computer

That sucks when you get burned because someone else was there monkeying around before you checked it. Good lesson though

Don't use your phone to test usb outlets Ivan.

The complex silliness of today's vehicles is only matched by their undependability.

Its already a process to figure out a issue with module laden vehicles. Then throw in a previous repair uncompleted uncompleted 😮

And now Ivan is going to get a call back for a parasitic draw my experience thats usually what people do if they have a draw, they just unplug it because they don’t want to do the footwork or they don’t want to replace it

someone is testing you 😂

Powers, Grounds, Connections. Basic OOPS. Move on Have a great 4th.

I could be unplugged as a security requirement.

Techs need to slow down and go back to basics. I've seen it multiple times techs grab the new snap on scanner that they justified the shop to buy off the truck but not use correctly, used for its value, then give up and handed off to another tech to diag. I then get the diag as 3rd tech and found a fuse to blown. I test drove the vehicle hard stops, bumps to see if I can get the fuse to pop. Shipped it. Next day the truck is back dead again. Same fuse. Turned out someone wired the aftermarket radio 12v key on power to the key sense circuit which a 2A fuse. I never turned the radio on test driving it thus why no idea.

A Buick, made in China. Go figure. Don’t know a thing about this stuff, but I do wonder why that was disconnected. 👍👍🇺🇸
