Want to win a test light load tester. Comment below #jarhead that’s #jarhead. Good luck to the winner
#jarhead it looks nice
Thank you for you're time

I am retired now but I would definitely hire you as a avionics Lockheed Martin tech rep. Aircraft, like cars have intermittent failures like this vehicle. You showed your fluent in diagrams and you don't give up but instead think outside the box on creating an environment that mimics the envelope that the failure occurs in. Starting pay is $85k and after 5 years you'll be over $100k. You should be making atleast that now in your driveway. I really enjoyed following along with your T/S. Good job
Hello from Chicago, this happened to me yesterday I have a Buick enclave 2011. I will order a computer. You got my subscription 👍🏻. I’ll keep you all informed. Great video. Thank you!
#jarhead I have been watching your videos for quite some time, always enjoy them. Never stop learning everyone.
Thanks for sticking to the channel Mike. We have some awesome video coming out in the future
Hot and cold tests can find the problem. Not always, but worth a try. Good one Oz!
#jarhead When I repaired tv's for a living the hair dryer and a can of freeze were my favourite tools.
I have learned a lot frome your videos . Keep it up oz
Great channel. The ECM on the Buick was bad. Did the car shut down while driving?
Mine shuts down while driving, 2012. Did you find a fix? I ordered a pcm, still waiting...
In my trade we do this to intermittent PCBs as a method. We also use freeze spray to make components super cold as well. A sound method usually used by us for tough dog problems. Cheers.
#jarhead Awesome channel Oz! 100k subs is right around the corner!!
Can’t wait Fred. For sure want to celebrate
I had a similar problem 2 yrs ago and it ended up being the ignition relay fuse, now 2 yrs later it's doing it again... Do these fuses tend to burn out ?
I’m in same boat. Did you find out what was wrong?
Mine does this what is the part I need
#jarhead. Thanks for taking the time to make videos
I like the stable camera format. I get dizzy when the camera moves too much. Thanks for asking.
Yea. That’s one thing I don’t like when I do live videos
Dude i just had one with the same problem. Pcm replaced. Give our love to the family. #jarhead
At what point did you use that tool that your giving away. I never saw it in the video?
Great job! Last year I had one where when the car would be soaking hot, the alternator would stop charging. Came 2 me after 4 shops, scoped it and during the test drive.....nailed it. #jarhead
#jarhead
Nice video oz. Live video is nice. Either way we are all learning! Thank you for sharing!
Thanks for the kind words Glenn
Hey OZ, love the technique you used on this one. It definitely takes a lot of time setting up those cameras and nothing wrong with old school videoing. We'll take you any way we can get you. Keep it coming!
#jarhead
So how did you fix this problem? Is there a part that needs to be replaced? My car is doing this.
Had a similar situation 2010 Buick Enclave sit overnight in the cold temperatures and the next morning no crank no start pulled the PCM out and heated it with an electric heater about 15 minutes each side put back in and it started right up consistently. scanner codes U100, U101, U121.
Those U codes are the easiest to diagnose.
#jarhead. Another great diagnosis and video!
Thanks for stopping by Bart
Thermal testing can uncover intermittent troubles at times. use canned air or ice-water for the opposite effect. #jarhead
Not a good idea to put water on a computer
I actually have a carb tool that blows cold air from one side and hot on the other. But it blows really weak
Great video brother
How do you fix it tho
Love your videos in any format. :) #jarhead
Question: did driving down the road keep it cool enough to not lose connection? I wonder if they ever got stuck in a traffic jam in hot weather if it would act up?
I've been a mechanic for 28 years. To answer your question it won't die if the engines still running. the starter connection inside the ECM gets hot and expands losing the connection necessary to restart the car once shut off. This is why it won't die as long as it's not shut off. Also if you ever have an issue with start stall those buicks have a wheel on the cam gear that runs the cam sensor. These wheels will break and pop up hitting the sensor causing the car to die. Many issues with those buicks.
Whats the diagnosis?
After watching that for 14 and a half minutes, did it actually start ?
Yes. Because this was a live video I didn’t show the repair. But I was able to get a new module and it started.
@@OzMechanicswhat module did you replace?
i have a 2016 Chevy Traverse Lt AWD and went to a store came back out no crank no start thought it was the battery got jump start no luck not sure what it could be it was running when I pulled into parking spot I had to have it towed back home tow truck driver said thought it was the starter any help would be appreciated ty
@jarhead love that tester
My go to load tester
Was up Oz. Quick question , was the pcm loosing communication to your scan tool when it was hot ? I'm wondering if that sent you down the pcm trail right away . Keep it up bro
Yes, the pcm lost comm. but what gave it away, was the check engine light not coming on
#Jarhead. Great lunch time tutorial
Thanks borg. Change it up to #jarhead so it can count
@@OzMechanics awesome didn't even notice.
Sure I want to win a test light load tester. #jarhead Nice fix. By the way, I read how the IJ help you with the parking requirements at your garage. Glad to see my donations to helped someone I know. Keep up the good work
#jarhead, awesome fix and diagnostic, but i do prefer the still camera, only because I get motion sickness lol
Is the pcm i had a caddy that did that
That's a cool little gadget you have there #jarhead. Maybe it can help my pitiful diagnostic skills
#jarhead, excellent video, very good explanation. #jarhead.
Thanks for stopping by Nelson. Good luck in the contest
#jarhead. I wouldn't have thought to heat the pcm to duplicate the problem. But now I will.
Yes. I’ve been using this method for a while. I actually have older videos where I heat sensors
Did ecm get replaced and problem resolved?
@ garhead. Like this style.
Change it to #jarhead so it can count. Thanks for watching
Nice diagnosis!
You’re a genius
#jarhead another good video thanks oz
Mine would do the same thing. My mechanic said it was the starter. But, it hasn't done it again in months.
Thanks for your time I learnd a lot from your videos i wish for you the best #jarhead
It good video, but I would drive and record data stream that also not bad way to find issue , if I am mistaken then correct me please
Great video as always thank you!#jarhead
Thank you for watching
Back in the old days, Chrysler came out with their (lean burn system). When hot -no spark. A water bath would get them to start.
Were you in the Marines at one time, Oz? #jarhead
Our Enclave with a new computer new battery doesn't start? Am completely at our witts end
Did you program the computer ?
We have not programed the computer yet,my husband thinks we need to go to dealership to do that,what are your thoughts?
Another great video, always great content #jarhead
#jarhead amazing work as usual.
Awesome old-school hood prop! #jarhead
Got to love it
Just know it will kill your battery while you wait so make sure you don’t panic just jump start it.
I just replaced a starter and it is not starting the car and it just makes noise
#jarhead Nice! Very informative bro
Thanks for the videos
#jarhead Nice test procedure!
Thanks
OZ, always good info and approach brother thanks for sharing #jarhead.cheeeeeers
Thanks for stopping by J
#Jarhead! Nice work!!
Thanks for the video #jarhead
Thanks for watching Maurice
#jarhead ,keep up the great info.
That's a pretty quick diag
#jarhead
All said and done under 2 hours
Nice video like allways #jarhead
Good luck getting an answer
#jarhead. Need to make me one or get yours. Great video.
Good find man #Jarhead
#jarhead great job 👍
They located the PCM by the radiator ? Why not attach it to the exhaust manifold. That's no common sense whatever. #jarhead.
Dodge diesels put there’s on the side of the engine and Mercedes puts it on top of them. Crazy stuff
@@OzMechanics Yeah.... I bet if you put that same PCM somewhere inside the car, it won't ever act up again. And if you get another PCM, within time that's going to fail. All because of heat.....I like this video format, it's a little shaky but I like it.
#jarhead and thanks for teaching 🙏
#jarhead nice way to test
Thanks for the content #jarhead that’s #jarhead
#what, no wait #ozhead, no no #jarozhead, oh I got it....#jarhead
#jarhead neat trick saves a lot of time. Peace

You are the man. #jarhead

I experienced that on a Mercedes car that has PCM on top of metal intake manifold. Stupid design.
