This guy is on another level, You do not come around these guys too often

Bernie you are an inspiration. That was simply brilliant and well-explained 🙂👍

This channel is great for learning characteristics of wave patterns. I have to watch these more than once to understand it. Lol awesome

You are the anormaly shooting master in our circle!

I have seen one 4.6 dohc in a Mercury Marauder have a worn out key slot on the wheel. Definitely not a normal issue but apparently it does happen. What I do know is most shops don't even know what a lab scope is let alone how to use it for diagnosis. GREAT VIDEO thanks

This diagnoses deserves more than just one thumbs up. Bernie just told us how the magic trick is done.👍👍 Nice!

Damn Bernie is on another level. Never seen this type of diag. Amazing

Only the mechanics that threw parts at this vehicle gave thumbs down! Thanks for sharing your knowledge!

I am amazed coming across this channel. I am wondering why so far only 7k subscribers. I am going to let many more aware of here.

Good Engineer, Good Quality Tools and Technology.

Bernie, You are absolutely right. Using quality equipment along with a method of best practice to capture and analyze the data is key to finding problems. I see the first 2 pieces of data you collected was the CRANK POS SIGNAL and the #1 coil signal. Then you retested with a pressure transducer, getting a reliable mechanical reference by way of cylinder compression and cycles. It still showed the ripple of the crank signal. Once you proved that the fault was a loose crank reluctor wheel and then repaired it, I appreciated your follow up to show a good crank signal with the tight reluctor wheel. THANKS SO MUCH FOR YOUR GREAT DEMONSTRATIONS!

Nice Bernie! Pico can graph the frequency of the crank but the E-scope does it flawlessly!

Great explanation of the VVT trying to compensate for the loose chain

WOW! Experience and the right tools won. I've never seen that before, and where I worked before retirement, we had V10 and V8 Ford vans from 1997 up to 2004 MY. Great Diagnostics. Knowing how to read the scope pattern has shown the problem.

The more i see this software in action, the more impressed i am! I originally thought the price tag a bit high, but after watching a few of these diagnostic procedures, I cant wait to purchase this! i can easily replace at least 4 diagnostic tools with this!

Awesome knowledge, Awesome equipment and awesome diagnostic. Congrats

PRODIGY Automotive Test Solutions 👌 From the start to finish loved it thank you very much Automotive Test Solutions From Nick Ayivor from London England UK 🇬🇧

Thanks Bernie for sharing this information it shows me how valuable a tool like the Escan elite can be in diagnosing

Bernie you the man.Thanks for sharing....

As I've heard other sage techs preach, "Never trust your scan tool data!" LOL really enjoyed the diagnosis. Thanks so much!

Absolute mastery, great job again Bernie.

Thanks Bernie, incredible to watch you problem solve

fantastic diag!thank you Mr.Thompson!

Dang !!! Good tool and experience... Nice find and fix Bernie

Absolutely amazing stuff Bernie. Thank You so much for sharing your wisdom with us.

Wow that was cool. All the best BT

Great diagnosis, thank you for sharing your knowledge.

Still finding ways to utilize the escope for further testing . Thanks for adding another valuable test to my arsenal .

Bernie you are a F ing genius and your tools are awesome! I wish I could give you 50 thumbs up!

Thanks for sharing your diagnosis Bernie. I appreciate your presentation and explanations in your work. Dave

Bernie many thanks for sharing your wisdom with this case study. One of the best if not the best video I’ve seen.

Impressive diagnosis with an impressive diagnostic tool. Thanks!

Bernie, you are AWESOME always good information and what an excellent tool u have.cheeeeers

Great video, brilliant findings.

Thank you for sharing your knowledge and expertise in the automotive world. Great videos!!!

You diagnosed something that would have taken a shop tons of money and parts in 5 mins. I am so damn impressed by you Bernie

At 16:18 I believe the cursor was placed a touch further to the right. I believe that added a peak on your crank signal. To be clear I don't think it changed your result. Thank you Bernie for sharing these videos. I am learning a bunch!

You are incredible Sir, not only a brilliant tech but a gifted teacher. Thank you for taking the time to produce these videos and share your knowledge!

Wow! Awesome work Bernie.

More gold from Bernie!! Keep em comin!!!

what a great video my respects for you sr that motivates me more to get back in college

very thorough explanation.

WOW - blown away !! This is the worlds best diagnostics i have yet seen ! You are sooooo good !! Shown it, explained it, fixed it !

This is a great diagnosis, please keep pointing out the anomalies in the wave forms as that helps all of us, including some of us using less powerful scopes and tools. The wave forms with information, I feel is the key factors, not always the specific tool. ( I understand this is to help sell a tools platform.)

Thank you for your time , God bless you

Great video i learned something today by u thank you.

Awesome... Thanks for sharing Bernie. Cheers.

Newer subscriber here.....all vids I've watched are VERY well explained....my only issue, I wish I would've started watching you sooner. I'm jokingly saying this b/c I'm learning SSOO much from you.... even w some of the vehicles I've fixed, your knowledge makes me feel I should be on tires and oil changes.😄😄 Thank you!

I am always impressed

Amazing troubleshooting. All that because some rookie didn’t install the harmonic balancer properly.

A true Mechanic!

Pretty cool video it’s remarkable how after that first waveform he made the call… had he been by himself he probably would have just called it and moved on… showed all of us the theory for our benefit

Awesome Bernie. I think I want an eScope now!

Wow, just wow!.

Awesome case study Bernie, I need to use this function more. As a long time Pico user the learning curve on your scope has been steep. The truth is, the comfier I get with the escope, it's fast becoming the first one I pick up for fast diagnosis. ⭐⭐⭐⭐⭐

Thanks Bernie !!!!!!!!!

Excellent!

The scope diagnostics and theory are awesome , but typically if the damper isn't fully seated there be other clues where to start looking , like customer mentioned it started running lousy ever since the front crankshaft seal replaced, and serpentine belt noisey afterwards. Luckily loose damper didn't trash the crankshaft, and end up needing the motor replaced. I think I would have pulled the crank sensor and looked inside with snake camera and tried a little pushpull on the trigger wheel with a long blade screw driver or pick, and try tightening the damper bolt before pulling the entire front of motor off if it didn't have chain noise or cam crank correlation besides.

You are a great one 🤓💪🏻

Fantastic 👏 👏 👏

I like how you burn the shop without outright burning the shop. "What we need to do is actually diagnosis it"... LOL But man, some of these shops. Sending em out without verifying the repair.

wow very good thanks

I always love your videos because everyone thinks a Tech's job is so simple that instead of paying for a diagnostic, you can simply go to an Auto Parts and they will tell you exactly what you need free! Wrong!!! With that logic, if I have a burning sensation in my loins I should just go to the Pharmacy so they can tell me what I have and prescribe the right medicine.

Awesome Bernie, no more to be said 👍

Good. I’m taking my van to your shop

I wonder what the power balance graph would have shown? If you see drop outs in the graph, but don't feel it missing that could be an indication of crank sensor signaling issues? Then it would be time to break out the scope and pressure transducer?

How is it that your scan tool can get live sensor data (coolant temperature, battery volts, vacuum etc) at the left of the screen while going to get mode 6 data? Every scan tool that I have ever used can only do one task at a time. Live data, mode 6, monitors etc. while eScan seems to be getting info from all different options at the same time, or at least allows you to (what it looks like).

Pico need to up their game!

This guy is intense 😮

Thank you

Great catch, but lm puzzled why the tone ring is moving ( even with the loosened harmonic pulley bolt)? My 97 f150 4.6 Windsor has a tone ring keyed with the crankshaft. Is this one set up differently? Just did a timing job (PM) and had to reuse my CS bolt. I purchased the wrong one ( I know torque to yield bolt) but reuse it. Going to change out but expect the tone ring position to still be good, or am I mistaken. Thanks

Absolutely amazing! Can this be done with other scopes? I want an escope so bad! Planning on an escan elite first though

I need your class 😺

Bernie..... have you ever had one that stumped you? I watched the Charger 5.7 misfire, and thought that was brilliant how you diagnosed it.

Wonder if you watched the signal live at say a smaller time base and set a trigger on a compression peak. Then watch the crank signal shift back and forth against the trigger point.

Can this testing be done on any scope? Or can it be done on a snsp on vantage? And do we need a cylinder pressure sensor? Not that I don't want a eSCOPE its that I got bit by the snsp on bug and was able to buy on credit/ payments. Thank you Berney Thompson.. And do you want a brand new Vantage in trade for a eSCOPE?

Genial 👍

Bernie, could you have use an oscilloscope and discovered the same pattern as the firing order pattern?

Where can I find a guy like this in Austin TX?

Where are you located? I have a 2008 E250.

What's ur rate per hour, and is it like first hour diag then add more time if u go over I'm assuming

Couldn’t the same test be done by comparing crank and camshaft relationship? I mean trying to detect the movement on the reluctor wheel for crankshaft.

Amazing. The average car owner has no clue how incredibly complex diagnosing modern vehicles can be and the associated costs for diagnostic equipment necessary to do that. On a side note, what were the pink/purple lines with the cylinder numbers above them you were using to compare ignition and transducer signals against?

Where are you located?

wow

Huh???? ....w0w!!!! I just got a '96 E250 for free. Now I'm scared to work on it. Dammmm....... I think he is way over my head. It's a van ...... Not a spaceship! Lol. I haven't use an oscilloscope since when I was an 2001 electrical Apprentice.

I can remember not so long ago when you didn't need a PhD and tens of thousands of dollar in test equipment to fix your car or truck. It's sad that industry had to over complicate car technology. Seems like there would be simpler and cheaper ways to reduce emissions and that would make cars simpler and cheaper to produce and maintain.

should've been done the first time but definitely by the second time back...

So the shop replaced a bunch of parts (charging the customer a ton of money) BEFORE actually diagnosing the problem? Hopefully this shop isn’t anywhere near me.

Bernie says to use logical, accurate thinking but unfortunately that's in short supply. Sadly enough most people would just keep throwing parts at it until they gave up.

Intakes are bad to get a vacuum leak...trust me... .lol

wow I hate ford. need to take the whole thing apart to change out coil and plugs. thanks for the info

Why I hate ford.

Your detective. Like automoBatman. The first moto loco guy is like this too. Detective.
