Diagnosing a 2014 RAM 2500 6.4L with Low Power and a Multiple Cylinder Misfire

[@JoesAutoElectric]

Nice one Bernie. No surprise a Chrysler with a failed PCM, but the video proves how important a strategy is when diagnosing. Most shops will have thrown coils and plugs at it.

[@HETPEZB]

No need to throw the coils and plugs. Simply swap good known ones with assumingly "bad" ones and see if the problem will follow or not.

[@andrewk778]

A professional sharing his knowledge and experience. Thank you.

[@kylefentz]

What a badass. Bernie is an idol to soo many mechanics

[@mikechiodetti4482]

Knowledge through Service Information and Experience, coupled with a great scope and the knowledge to use it, equals positive results. Good one Bernie.

[@autorepairbymike1356]

Thank you Bernie. Very happy with my Elite 4

[@vickenkaragozian2041]

Great suff.. this scope is great , it has its own sensor simulator and the coil tester which supplies pulses to the ignition coil to fire the coil.How amazing is that. I own this scope the 4 channel and i use it everyday..Thanks Bernie

[@orville58]

It would be so nice to have half this much knowledge thank you for sharing your knowledge and time keep them coming

[@sergesimonov1767]

Thanks for the knowledge and experience you are sharing!

[@theautomotivedoctormr.wils9217]

Thanks for sharing more great tips with the tool , very pleased with my purchase . Keep them coming .

[@and0pand0]

Stoked I found this channel, man.. the information you're sharing is awesome. Some BMW stuff would be rad!!

[@automotivetimelapserepairs1782]

If you want bmw stuff I'd suggest checking out diagnose Dan's youtube channel

[@ismarmeskovic]

Thank you for your video Mr.Thompson!

[@neverstoplearning382]

This is just amazing. Thanks for sharing.

[@JoelAutomotiveInaction]

Very nice to watch your videos , A lot of learning from them

[@gonzgarr1592]

Bernie you are the best thank you

[@robertfrancisco1193]

a true MASTER TECH !

[@IAMNOSLEEP]

Thanks for sharing Bernie... Cheers.

[@e.l.9589]

I wish you were near me to bring my PO300, multiple dealerships can't figure it out on my 2017. Only happens on heavy acceleration.

[@baxrok2.]

In depth and very thorough. Thanks!

[@timbankston3723]

Great information- Have you ever run across the "Vibration" issue with the HD series Ram? Rear end shake usually 55- 70 mph depending on the truck?

[@mike-yp1uk]

That was really well done.

[@francelinguerrier8832]

very nice bernie i have been watching your video quit a while and i'm tempted to buy the escan elite but i have a quick question . Does the escan has the bidirectional function ?

[@CartersDiagnostics]

No, It does not.

[@PineHollowAutoDiagnostics]

Beautiful diagnostics, Bernie! Wow how could 3 coil drivers blow simultaneously? Probably a control chip issue for those drivers. Shame that a computer only lasted 6 years...

[@ablackformula]

Are two-wire coils typical to Chrysler? I thought it was more common to see 3 wire coils, where the pcm driver wouldn't be doing all that hard work, so to speak.

[@Arphand]

Chrysler still uses 2 wire coils on most stuff. Most everyone else uses 3/4 wire coils.

[@steveanderson4553]

Excellent video !! Thank you !

[@liviu2004]

Scoping the ckp would reveal more insight?

[@billyyoder8171]

Thank you Bernie. Good job. How many amps can your scope driver handle? Have a blessed and safe week to you and your family.

[@abelscaliber7969]

Makes it make sense!!!

[@jgeorges3061]

BERNIE, UR AWESOME as always thanks for the knowledge sharing and exceplyning.

[@ganeshnarayan5505]

Great video Bernie learned a lot from you thanks.

[@turbo8711]

Excellent video

[@teedubya5772]

I wanna know where your shop is and personally request you to fix any of my future issues. No matter how far! lol 👍🏻👏 All jokes aside, good mechanics seem harder to find these days

[@aymenmohamed1134]

Awesome

[@martinarrieta248]

Which is a good scope I want to buy one

[@scientist100]

4425a standard kit.

[@tonyfremont]

The pico 4425a is a really good scope, but the escope used in this video is in a league of its own. It's 8 channels vs 4, so try not to choke when you see the price. Still, it's a real automotive diagnostic tool that goes way beyond a pico. Everything done in this video (aside from reading the DTCs) can be done with a much cheaper scope, but only at a small fraction of the efficiency.

[@scientist100]

@@tonyfremont I notice that this Technician tends to use more than 4 channels to get you to buy the 8 channel but is not necessary. What you see is that more than 4 channels tend to get on the way. Unless you have a special case where you need more than 4 channels, then I would just pull the cheap Hantek but it is really not necessary, I like the option to ground things that he does but you can also mimic that with a tap to the ground with a fused wire to a back probed pin to see the reaction of the injector or coil.

[@tonyfremont]

@@scientist100 yeah, the pulldown output and TTL generator seem a bit fluffy, but they do increase efficiency. The "red light" as he calls it is more fluff, but it is unique and does let you know that a prove is connected to something. I think that is done with a really weak pulldown to a negative voltage (below ground potential). If you know how to use a scope, any scope will do. Otoh, escope and pico take the approach that mechanic is not an engineer or mathematician and needs extra help when setting time bases and voltage scales, or converting the voltage output of current clamps to actual amps. The escope does a lot of other things too, making it a full diagnostic tool for automotive use. It's too bad that you're forced into buying the most expensive windows tablet on the planet to use it. I'd much rather they'd written their software for android or even generic Linux. Tablets are easy to break and replacing a Microsoft surface isn't cheap.

[@vickenkaragozian2041]

I have the Elite4 , 4 channel scope.. You don't need the 8 channel. Its different than the Pico scope but has great features like TTL which puts 5 volts on and off signal to pulse the igntion coil transistor or to find if a wire from ecm is shorted to ground or if the ecm is grounded or loaded internally. Plus it can handle maximum 500 volts like if you were checking ignition primary voltage or injectors.. Primary voltage can easily go over 300 volts..

[@jovangomez9380]

Escan elite is compatible to asian cars

[@sargetester99]

I like it....but.... you didn't check if cam and crank are ALWAYS in correct time, while it was misbehaving. A loose reluctor wheel or faulty sensor can give you that behavior also.

[@dimasrodriguez3155]

Bernie for president

[@turningwrenchesautorepairm5017]

Who the heck gave a thumps down B^[ ..... Get the FBI on the phone !!!

[@HD2O13XL12OOC]

Um ok so the coils are bad. Got it.

[@rubengarcia6920]

Doge loves to shut down drivers when it sees a problem it can send you for a loop sometimes

[@robertferrara4529]

very through.

[@mediilbrahim2835]

I hope one day I meet you and kiss your head !! God blessed you

[@muhammedsons2675]

As a brother advice do not throw your money away by buying their worthless scanner, I wish I didnt buy it from them, it was the first mistake which I made in my life I regret for that be aware not to do so I warned you just for sake of God.

[@mikefoehr235]

I had a 13 Tacoma...had 170 000 kms when i traded it in. I never not once seen any of these issues. Shows you how crappy Ram is vs Toyota.

[@jeffs2809]

Using your logic, since my Ram hasn’t had these problems, my Ram is as good or better than Toyota then.
