Mr. Thompson never ceases to amaze me. ATS products are top notch!!

[@mechanicmatt871]

It's great watching someone this good show you how they diagnose, thanks for sharing

[@PineHollowAutoDiagnostics]

Wow that was crazy! Thank you for the video, professor! :)

[@jordysandino6577]

Hi Ivan you’re another profesor of mine . Thank you sir for your good videos as well .

[@FinalStopMobileAutoTech]

This man is definitely one of my heroes! Keep em coming Bernie!!!

[@gustavomartinez324]

Damm Bernie your knowledge is insane and how u use the scopes mad scientist truly one best in automotive filed

[@timbonjovi]

Wow! Shade tree mechanics are long gone. It's really amazing how complicated it is and how good this man is at his job

[@markferraro5250]

great video Bernie thankyou im digging that battery screw trick keep em coming

[@BryanByTheSea]

Love to see a biography on your journey to how you became so versed in the automotive field

[@richardostrowski6420]

Very impressive diagnostic. Training and equipment are key in this day and age.

[@8power0]

I HAVE BEEN READING ARTICLES BY AND WATCHING VIDEOS BY BERNIE THOMPSON ALL MY LIFE AND HE STILL IMPRESSES ! ! !

[@mikemerola5263]

Bernie you are the best ... i just bought a escan elite today..

[@terminaldiagnostics5576]

Wow good thinking strategy using voltage simulation to prove PCM issue brilliant work loved it

[@DylanRabier]

Great video. Lots of diagnostic info. Thanks for sharing 👍

[@caiocesar4136]

Every day learning from Mr. Bernie, thank you from Brazil

[@BlackOpsJuJu]

Great Diagnosis Amazing I must say you are the best of the best of the BEST !!!!!!!!!!!!!!

[@eliteautomotivediagnostics4424]

Great video Bernie. interesting fault with the bias voltage being pulled down. great conclusion.

[@atiqkhan6683]

Great Diagnosis Thanks for sharing

Great video Bernie.

[@alanw5879]

Hi Bernie, another great video, I was just wondering when youre injecting a 5 volt reference like that, do you usually always have it set to 25Hz and is there any danger to the ecm by sending 5 volt ref under certain conditions? Ive been building some circuit testing devices like this and was trying to find out what freq the 5 v ref should be. And is there any particular mosfet used? is there a 10k resistor across the mosfet gate and source? You guys at ATS have some sweet tools..

[@CartersDiagnostics]

I'm curious as to what the O2 signal voltage would have been if the scope would have grounded to sensor ground Instead of battery ground.

[@jordysandino6577]

Hello sir . I always enjoyed your videos uncle berny I have a question I know you look at the scope and determine that the o2 was pull down but how do you know that? All I see is re red line down but how to know that it is a pull down and not a bad 02 ?. Thank you sir

[@orlandocortes8022]

Bernie,substitulos en español ,gracias 😁

[@jesushernandezbrito3342]

very profecional system.

[@SimplyDiagnostics]

Another Masterclass, thank you for sharing Bernie 👍

[@elpelonsitoelpelonsito3659]

One of the best 👍 thanks.

[@Eagleoneradiogod]

I still have the original computers on all my cars. But then again. There all inside the cabin.

[@maconthelt6963]

Is this sharpshooter built into the EScan? I get a little lost when you jump between things, it almost sounds like these are all add ons? The Escan isn't a cheap tool, looking at it on AESwave website it doesn't give a clear breakdown of all the options it has, I don't think anyways.

[@scaracci24]

EScan has the sharpshooter

[@Mario241]

Amazing thank you for all the good info :)

[@orlandocortes8022]

Me gustaría que hubieran subtítulos en español

[@Scott-ms5bb]

I wish you could fix my 2015 Gmc Terrain.

[@PicassoPete]

Wow! So many more things that can go wrong or give misleading results. I think I need a larger brain folks! Hahahaha. To think that the old Suck, Squeeze, Bang, Push has become so super sophisticated. Lol. Great video as always Bernie, many thanks for posting. Where would we be if brilliant people didn’t pass on their hard earned technical knowledge and experiences. Again many, may thanks, it is truly appreciated.Regards, Peter A. (PicasoPete151)

[@seapeddler]

Put that PCV valve up high in the oil filler cap. The way it should be.

[@johno5323]

Are you in Albuquerque NM?

[@charlesbarkwell7693]

www.automotivetestsolutions.com Shows that they're in Albuquerque, New Mexico... He also allows their equipment to be sold @ www.aeswave.com Fresno, CA.

[@autojoe]

Gm never ran a ground bias..... This one 1.27 volts. Gm always ran a 450mv signal bias. Do they run only ground bias on this vehicle or do they have both?

[@johnhnetkovsky8917]

Note: The low signal circuit is tied to a pull-up circuit within the engine control module. A voltage of 0.0-1.10 V on the low signal circuit is normal per G.M. S I.

[@johnhnetkovsky8917]

Test for 1.7-3.0 V between the high signal circuit terminal B and ground.

[@johnhnetkovsky8917]

Connect a 3 A fused jumper wire between the high signal circuit terminal B and the low signal circuit terminal A. Note: The low signal circuit is tied to a pull-up circuit within the engine control module. A voltage of 0.0-1.10 V on the low signal circuit is normal. Verify the scan tool HO2S 1 or 2 parameter displays 0.0 V.

[@rodvan-zeller6360]

and if anyone is wondering how to charge for this type of work , it is simple ,stop charging per diagnostic hour and start charging for each diagnostic test.

[@2nickles647]

You charge for all the time it takes to diagnose the vehicle. There is no simple or average charge.

[@rodvan-zeller6360]

@@2nickles647 How do you deal with the bureau of auto repair rule of giving an estimate? Since you do not know how many hours it will take.

[@JoesAutoElectric]

I am at a loss for words...that never happens...

[@memphisautodiagnostics4136]

I want this ATS system with the scope

[@Usmanthemecano]

I need someone to translate this video in english for me please lol

[@thefinalroman]

Yeah I'll stick to old cars...

[@MrBeefsnorkel]

i hate it when its supposed to put out, but it doesnt

[@Darjan_Spasojevic]

Put Mr Beanie and Eric O together they could fix our government
