  1. Avataaar/Circle Created with python_avatars Jim A says:

    You would think they would have much better connectors to deal with the environment they have to deal with.

  2. Avataaar/Circle Created with python_avatars MARCOS MATEO says:

    I got my Ultra Coming!! Watching this video gets me pumped!! 💪🏼 Thanks Alot Man!

  3. Avataaar/Circle Created with python_avatars Bloody knuckles Automotive says:

    Does this work with the old GM vrs abs sensor signal? I didn't see a sine wave option on the autel drop down menu.

  4. Avataaar/Circle Created with python_avatars Zoom Auto - Mobile Repair, Diag, Programming says:

    You're a pretty fart smeller Eric. I mean "smart feller" as you said.

  5. Avataaar/Circle Created with python_avatars MegaMarclar says:

    I have been looking at this same scanner for my home shop… The signal generator is a nice feature, but its only in the fine print that you need ANOTHER scanner to read the signal is not very fun… Seems like they should work on an update to the software that would allow you to generate, and read at the same time, with the same tool.

  6. Avataaar/Circle Created with python_avatars Joe electronic schematics for auto says:

    Yes signal generators have been around for many many years for RF and audio what you could have done after you isolated the connector you could have gone from the place that you pierced to the connector ends to measure continuity to make sure which looks like it is the problem

  7. Avataaar/Circle Created with python_avatars David Gutierrez says:

    Good

  8. Avataaar/Circle Created with python_avatars ~FERAS ALZOUR~ says:

    Can you please send me the name of the test leads and probes you were using in this test

  9. Avataaar/Circle Created with python_avatars Kai Kendall says:

    1 minute into first video and I can tell this guy is a clear-thinker.

  10. Avataaar/Circle Created with python_avatars Sebastian Villela says:

    Can you make your a vehicle run through generating crank or can signal with this machine

  11. Avataaar/Circle Created with python_avatars TStriegel1977 says:

    Hey Eric, do you have any experience with Forscan for Fords? I'm curious what you might think about it, compared to all the other diagnostic scan tools you've used over the years… Love your vids, always Informative & Entertaining! Also, don't let a few D-bags rattle you, there's always a few in every crowd. 👍🏻

  12. Avataaar/Circle Created with python_avatars MRM says:

    Bitching??? We don't need no stinking bitching 🙂 Good video. Where can I buy those wire piercing clamp on probes? For what it's worth, wish I could get free stuff from Autel 🙂 I just upgraded from the MK 808 (good scanner but zero bidirectional control) to the MS 906BT…….yeah!

  13. Avataaar/Circle Created with python_avatars 1FNJO says:

    I think If you saved a few of the hundreds of bad GM hub assemblies where the sensors are still functional, you could just use one of them as a signal generator and save a few Hertz on the ole pocketbook :-))

  14. Avataaar/Circle Created with python_avatars john briscoe, jr says:

    Hey South Main, I've been learning from guys like you for a long time, thank you! I've just purchased the Maxisys MS919. The haters are my motivators. Fact: there is no one person in the history of mankind where 100% of the people liked or loved that person, never! If someone gave every human being in the world one million dollars people would still complain that he could have given us 2 million or he did it to show he's better than everyone, etc….You can find the most perfect human being from mankind and someone will have a negative view, opinion, and/or perception about their humanity. DON'T QUIT, PUSH ON!!!!

  15. Avataaar/Circle Created with python_avatars Moving Forward says:

    Awesome job brother I can't wait to the Day i get this expensive piece of equipment

    "It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."  –

  17. Avataaar/Circle Created with python_avatars Anthony Pegues says:

    Thank You for the video, I just bought the Ultra and am still learning all it’s capabilities, it’s just Badass!!

  18. Avataaar/Circle Created with python_avatars Reliance Auto Mechanic says:

    Hi, So I just bought the Autel Altra and I would like to see how do you make wave Generator step-by-step if that’s possible thank you

  19. Avataaar/Circle Created with python_avatars AnyThingFun says:

    Awsome i just got my ultra and want to learn more

  20. Avataaar/Circle Created with python_avatars Kenneth Franklin says:

    One more thing….a signal generator would be great for teaching modeling mathematical functions. As I mentioned below, I teach math. You discuss the science of electrical current, potential, and resistance, and the measurement units that go with them. You talk about pressure, transducers, and signal generation from many devices. I love these videos because you teach problem solving, logic, and reasoning skills, and above all perseverance. So many students I teach suffer from lack of these basic things. It's hard to teach it, and you do a super job. Keep up the good work. Stop by for a beer if you're ever in Johnston County, North Carolina. Our cars are really clean. No rust.

  21. Avataaar/Circle Created with python_avatars Kenneth Franklin says:

    I'm always confused by the concern about negative comments. I usually look down through a dozen or two of the comments and never see anything remotely negative. I think these videos are amazing. I'm a public school math teacher (and not bad at it) and you are an amazing teacher. If I didn't know better I'd swear you were a Navy veteran. Like me.

  22. Avataaar/Circle Created with python_avatars Aaron Hargreaves says:

    You can split screen the Ultra so no need for two scan tools 👍

  23. Avataaar/Circle Created with python_avatars Aleiyah collado says:

    after this, i realize how much time you can save to verify a bad wiring, using a signal generator!

  24. Avataaar/Circle Created with python_avatars JAMIE WEEKS says:

    Good video. I believe I saw where you can do a split screen on the Ultra to show your wave generator and your data side by side.

  25. Avataaar/Circle Created with python_avatars Alan W says:

    Pico and hantek have signal generators, I've always thought they were only for dialing in probes, atleast that's what one of the hantek manuals say. But I've always thought of injecting a signal to diagnose, just to nervous to do it, seeing you do it first helps much. Thanks 👍

  26. Avataaar/Circle Created with python_avatars Big Motor says:

    I just got one too. Thanks for sharing that info!

  27. Avataaar/Circle Created with python_avatars J Clare says:

    I am new to Autel and really like the TS508 TPMS tool. What scan tool would you recommend from them or what is your goto scanner that you have been using? Thanks, watch your videos all the time.

  28. Avataaar/Circle Created with python_avatars Bruce Kaiwi says:

    Great video as always. Gotta grow a thicker skin for any complainers.

  29. Avataaar/Circle Created with python_avatars Gregory McLean says:

    Seems like this would save a ton of time.

  30. Avataaar/Circle Created with python_avatars Christian Diaz says:

    That's a great way to use a a signal generator, before this video I didn't know that those things existed, I like watching your videos Eric, at least I can learn a trick or two. Keep up with the good work

  31. Avataaar/Circle Created with python_avatars Anthony Sands says:

    Loving the wave generator 1 question how do you find the information on what the sensor is looking for ? Keep up the work watch your videos everyday 👍

  32. Avataaar/Circle Created with python_avatars Tristam Thomas says:

    There is some talk in my area about the Launch X 431 V Pro. I am curious if anyone has had any personal experience if this tool can compete with Snap On Altec or Matco Professional Features; i.e wiring diagrams and troubleshooting features. Mrs. O opinion will trump all other comments

  33. Avataaar/Circle Created with python_avatars La Casa del Sensor Nicaragua says:

    Great video!!! But you can go to split screen, there's no need to do it with two scanner I guess.

  34. Avataaar/Circle Created with python_avatars YK Mini says:

    excellent video. As you said clearly not everyone can afford that equipment but why not show some uses. I have been wrenching on cars for 30 years as a hobby and am learning a ton from this channel so far and I am only a few videos in. Thanks for the quality content.

  35. Avataaar/Circle Created with python_avatars John Barry says:

    Great, another tool I "need" for work. Wife will be thrilled.

  36. Avataaar/Circle Created with python_avatars Brett Hopenwasser says:

    Love the content.
    Is there any reason you didn't use the split screen function with the ultra. In stead of two scanners? I'm trying to learn to use this tool.

  37. Avataaar/Circle Created with python_avatars Labrador McGraw says:

    What a fantastic piece of kit… sadly, it's way out of my income bracket. In this example, you'd still need the experience to know about those ABS connectors being junk to use the equipment effectively. Those wire-crimping gadgets look pretty cool too.

  38. Avataaar/Circle Created with python_avatars Julius Roberts says:

    Uhhhhhhhhhhhhhhh teacher, what?

  39. Avataaar/Circle Created with python_avatars wakefieldyorkshire says:

    When Bob Dylan was getting booed for going electric in the sixties he said to his band play it louder. So Eric use as many of your diagnostic tools as possible; it's a treat to see them in use and have them explained to us and, as always we learned something.

  40. Avataaar/Circle Created with python_avatars Mark Chidester says:

    Now that was cool!

  41. Avataaar/Circle Created with python_avatars Wes Hawkins says:

    Good video Eric. The electronic diagnosis and money light videos are the best. That’s the part of the game I have the most trouble with and learn the most from your videos. Keep these coming.

  42. Avataaar/Circle Created with python_avatars Crispr Talk says:

    This video needs a Scotty title like… "If you're not using an Autel Maxisys you are stupid!"

  43. Avataaar/Circle Created with python_avatars S&D Family says:

    Don’t let these ass pirates get to you! You don’t owe them anything! I’d like to get your feedback on the Autel ultra, and what scanner you like more.

  44. Avataaar/Circle Created with python_avatars Patrick Madigan says:

    I have a signal generator for troubleshooting too… Nicely Done!!! =)
