Autel Maxisys Ultra: Signal Generator To Diagnose ABS

[@SouthMainAuto]

It's funny to see how quickly the comments will start to shit on you for using expensive test equipment. I stated in the video directly that this equipment was out of reach for some folks but there were many ways to do this job. It is directed for shops who already have or might have these tools however do not use them to their potential. Everyone one that is bitching have the same opportunity I had or have. I started this business 16 years ago. I got married, bought a business and started a family. I started with the money I had saved from working, I lived in a single wide trailer, I drove shitty cars and Mrs.O. worked two jobs while I worked day and night for 7 years straight. No vacation, and no honey moon, no health insurance, no government assistance, nothing. If you think I was fed with a silver spoon and sit here blowing people for their free tools you got it wrong. Do I get free tools? You bet. I do, Danner does, ETCG does, Kilmer does, we all do. It's called marketing. Do they pay me to tell you they are good? Nope. I worked my ass off to get where I'm at. If you have an issue with it and want to discuss it like a man, stop by the shop.

There’s always gonna be some little bitch out there to whine and leave nasty comments. Try to ignore them. Love your videos. Wish there was a shop around here that would invest the time n money to do good diagnostics for their customers and just throw parts at it.

[@da_chief]

Been waiting for you Eric to finally get this tool so I can see all of the benefits from a real Pro using that tool for real live testing....I want one bad and I don't give a rats ass how much it costs when it comes to investing in my business....the time you save by using the proper equipment and the know-how to use the tool properly is what really matters! I love your videos and I can spot a true technician when I see one, thank you for all your wonderful videos and by Christ, you should be compensated for all you do for all of us technicians that you help out!

I would disagree with your statement " I talk too much" that's actually one of the reasons I watch your videos. Listening to you talk yourself through a issue, is where I personally get the most help.

[@brianburns7211]

I agree. It is no good to just say “do this.” By knowing the thought process that got you somewhere give better insight as to how to reason out a problem.

I've said the several times on here, it is his process that makes him so good and such a good guy to watch. He doesn't know it but he is an excellent teacher.

[@spelunkerd]

I have an inexpensive signal generator that I thought I'd use often, but it tends to gather dust. Part of it is uncertainty about the character of a good wave, especially when talking about sending a live signal into sensitive electronics. That said, it is time consuming to find long jumper wires to crossover a signal from one wheel to the other side, and sometimes there's no positive control for a sensor in the car. What I really like about this video is your willingness to try new approaches, always expanding your horizon and skill set. There's a life lesson for us all.

[@peterphilipse8792]

The ultra comes with examples of good waveforms so they can be replicated.

[@billrimmer5596]

I remember Scanner Danner in many of his videos would try to fool the computer by touching his test light on and off, in order to simulate a crank sensor. This will b a feature he will especially appreciate!! The Ford VRF signal was one that would sometimes give him difficulty. Thank u for all the great work u do. 100 times better than Netflix!!!

[@SouthMainAuto]

I used to test light generated crank signal to this day. Pulled up or pull it down is all you need to know and it is a great tried-and-true bypass test 👍

I love using your saying. when somebody honks as they go by at work that honks "hey it's that guy" it cracks me up everytime I say it. Also "well there's your problem lady " when I find loose battery terminals on first visal inspection.

[@TheKajunkat]

I used that the other day. My son was having trouble starting his car so he called me over. I walked up to it, shook both battery cables and they popped off and before I knew it, I looked at him and said "There's your problem lady!". He screwed up his face and gave me the evil eye and says "Gee thanks dad.." Haha.

Naw he'll have two buyers . Since I retired from my second career, i also started up my own auto shop . I have been working on cars on and off since the early 80's . But I always enjoy watching Eric o impaticulair because he gives out a ton of extremely useful information in his videos. Not calling any names but Eric o's videos are not boring like some of the other guys on here . Plus he is a great example of what anyone can accomplish if they're just willing to put in the time blood sweat an tears . Thanks Eric and the lovely beautiful miss o for the great videos

[@davelas8465]

Mr. O please never apologize for using any "high tech" tool to diagnose a problem. True, most of us diyers will not be able to afford that Autel tool but why would we buy it for the 1 or 2 times we would need it. That's why we have good mechanics like you. The diagnostic process, by itself, is priceless. Thank you for demonstrating the options and use methods of your new tool. Your quality information will help us customers speak intelligently with our trusted local mechanics without undue stress when we have one of those difficult signal loss problems. We need all the "tools" we can get. Thank you for the excellent videos you offer.

[@metoon3092]

Here it is fellers; I turned wrenches for 7 years, then begun selling Auto Parts for the 2 largest Auto Parts chains. I speak daily (for 29 years ) to DIY customers and Professional Repair shops. I learn different things each day. We are in the midst of a heavy on-line offering of like parts - that we have on our shelves. It is touch and go regarding quality. Eric O. and that Ivan guy, they diagnose, research, print diagrams and grab all the info they can. If ---a Repair shop is equipped with the latest knowledge and tools to diagnose and repair, so be it. This particular channel was not solely broadcast for economical ( cheapest ) repairs. It is to properly and in a timely manner DIAGNOSE the problems. If that can accurately be achieved with a 10mm wrench and a scope on a rope, Great ! Though, it may be much wiser to use later technology to get there. Latest technology and modern equipment cost bigger money. A1 Mechanics like Eric O. and Ivan seek out what is best for each type of repair. Again, I daily am speaking to DIY customers and I am visiting shops. I see the parts they are putting on customers' vehicles. I see the " return " parts back to the store. I look at each and every NEW and Warranty return. The average SHOP is so similar to DIY'er Jack on the weekend; Read a code on the scanner, purchase the part, bolt it on, remove it when it DOES NOT fix the vehicle. Last words, Drive on Eric and Ivan, You both are rare in your field. Truly. If others do not like it Tell 'em what Mick Jagger does,...." Hey Hey You You, GET OFF OF MY CLOUD "!

[@deanmckee1385]

Info is key. Wiring diagrams are must!!! Access to the info??? My boss told me we should diagnose computer vehicle before they had computers to diagnose them🤔🤔🤔🤔🤔 I have been in this since 1983 I think the first think to retrieve information was a Diagnostic Data Reader. And a 4 inch thick trouble shooting manual. Yes my boss was a parts guy. Eric you are awesome with all the latest technology you show your viewers. This is why you have so many subscribers. Not to mention how you welcome us in to your garage. Thank you

[@goodpplz123]

No matter the cost think about the time saved which equals labor hours or money. So he’s able to do more, the customer saves because he’s not just throwing parts at it and everyone wins. This is the same with any industry or job. I have to have specialized equipment that costs a fair bit on the PCB board repairs that I do but I can get more done that way. I started out with the cheapest crap and worked my way to better tools. That’s just how it works. I’m not a mechanic other than a shade tree on my own vehicles but Eric is a great teacher and I have learned some nifty stuff when it comes to electrical stuff.

[@BigDaddy_MRI]

In my opinion, you are doing an outstanding job of shortening the initial troubleshooting, and shortening the whole repair cycle. So, by using the latest tools and test equipment, you’re 1) Bringing value to the shop, 2) Shortening the troubleshooting cycle which lowers your cost and you can pass that value to the customer 3) Improving your knowledge of how and why some systems work the way they do in various vehicles. Expensive? Yes they are. Do they allow you to move quickly from vehicle to vehicle? Yes they do. There’s no down side, and over time, these tools will optimize how your shop works, especially in the rust zone, where you work, and have so many strange electrical/electronics issues. Heck, with some other tools, you could start a cluster repair/microsoldering repair station that also fixes PC boards! You virtually have a lab setup: DVM’s, Oscilloscopes, signal generators... all you need is a good soldering station and a microscope with built-in camera and you’re fixing iPhone motherboards. The criticism is going to be fleeting, as you show how these tools work. I’m really impressed how you demonstrate how the signal generator works!! Good on ya!! Cam and crank sensors/wiring, speed sensors, pump speed sensors, anything that uses a pulsed control loop... I imagine you can also simulate a PWM signal also. The way of working is getting more complex because the vehicles are using technology that is moving forward rapidly. I2C high speed communication, fiber optics, microcontroller modules for everything, logic systems that make real time decisions in microseconds.... sounds like a MR or CT scanner. Still the best troubleshooter I’ve known. I showed my mechanic friend, Tim, your video, and now he wants to go work in your shop and get trained on the “good stuff”. LOL!! Thanks for a GREAT video. Excellent!!

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.

[@stusims1702]

I admire Eric O's tenacity, integrity, and work ethic. He knows stuff and is kind enough to share it with folks like me that don't always understand what he's doing but regular as clockwork, by the end of his video, I find I know much more for it. Regardless of the tool he uses, it's the tool between his shoulders that "always" stands out and the candor of his delivery that makes him exceptional. Good on you, Eric! Looking forward to seeing more uses of that Autel. Most of all though, thank you. You're great. Much thanks to Mrs O for being no slouch of a mechanic, either.

"Heeeyyyy, it's THAT guy!" gets me every time 😁 The timing of this video is perfect, since I'm in the market for a new scan tool. Didn't know it had a built in signal generator and that's worth its weight in gold. Thanks, Eric!

[@jamesfarnham1976]

I remember years ago a Dealership telling me they spent $800 on their scan tool from GM. A few years later the tool was $4000, a few later $7800 and then a few years after that it was $14000.00. OMGosh I said you need a PHD to use one....and the Mechanic said "just about". I know I'm lost when it comes to deciphering the problems today but I'm sure glad there are guys like you Eric that do! Thanks for the great videos! Jim.

[@AeroVortex92]

The stupid part is that the cheap tools talk to the car the same way as the expensive ones do. The only difference is the expensive ones know how to access extra parameters. The code to read the data is the same on both tools, but the expensive tool knows the address of the extra parameters.

[@2secondslater]

@behexen250 I think what Aero is saying is pretty much all scan tools have OBD2 capability, the producers of the pricier tools have paid manufacturers for the coding to interrogate non-OBD2 and/or proprietary codes and/or bi-directional controls, the difference between a cheapie code reader and a functional diagnosis tool is like chalk and cheese.

[@billyyoder8171]

Thank you Dr. O. Good job. I seen this Autel Maxisys Ultra at Harbour Freight last weekend for $2895. I'll have to get me one this weekend. Have a blessed and safe week to you and your family.

[@Garth2011]

Nice tool. What makes it better is that the signal is always on for example so you are not in and out of the car turning the key etc. Signal is on, you can trace it full time without any interruption until you find the open. Interesting tool to get used to.

[@j.o.a.t9718]

If you get anything from watching Eric's videos, it's that you can take your vehicle into a garage and have an idea what is causing your vehicle issue. Too many times, and I have seen it myself with my own automotive work, Eric shows how garages are charging paying customers for parts they don't need. With the right tools and some proper training, these unnecessary charges can be avoided. I am a DIYer though I have been working on vehicles for 30 years. Sure I would love to have a shop like Eric but that just ain't going to happen. Though watching Eric, he has taught some things and ideas which I have used and it has saved me time and frustration, and my customers money. Win win. Keep it going Eric.

I have always built cars and did some pretty cool things way back in the day. In the early 70's computers started coming out and of course, talk started about how these small little shops were going to be a thing of the past. Worry about needing all kinds of expensive tools, and the cost of buying computer diagnostic equipment, I had a choice to make. Keep working on cars or go into the carpentry business. Well, I figured sawdust was easier to clean off then grease. Anyway, I think I made the right choice, and built a carpentry business. I love watching Eric, I learned something new today, I have never seen a back probe. I always just cleaned the wire back and than shrink wrapped it. Live and learn, thanks Eric, I've been away a long time but, you keep me updated on things all the time, Thanks..

[@johntuttle5396]

When the quiet man speaks, one should listen carefully. When I started watching this video, I thought I was just going to comment on how good mechanics are always excited to get a new tool - either electronic or mechanical. There are times while you are working when you say to yourself, "Now why doesn't someone make a....." or "What I really need is to see that data in this different way because..." So after jury rigging a solution that works but is not "smart" or solving a problem by "taking the long way around" because that was the only way for you to fix it - and later seeing that someone "listened" and now there is a cool tool that makes something difficult very easy you're - happy. It is the process that brings a good mechanic (starting out) from a basic "tool starter set" to chests of tools. A mechanic buys a new tool because he knows it will be really useful. If he see's a cool tool but he wouldn't use it enough to justify buying, he figures out a work around (and also make sure he has some good friends). It really gets me sometimes when some people act like those who have a well developed skill set only have it because it was somehow magically bestowed or you were born with it. You mentioned your seven years straight of very hard work. It was also seven years of paying attention, always thinking and trying to understand and as a result getting real, real good in the process!!!!

[@mikechiodetti4482]

Many times in the past I wished I had a signal generator like that one. There were some out there but they were for the electronics industry and were expensive. Good show Mr. O! Diagnostic work can be profitable, especially when you learn something new.

[@zx8401ztv]

And since the signal is in the audio range, a small amplifier from say an old radio could be used to listen to each pickup (d.c blocking capcitor required), for the man that does not have enough pennys for the pro tool.

Eric, don’t let these idiots get to you. Please keep up the good work and produce more videos which are not only entertaining but as a keen DIYer, have saved me hundreds of pounds in garage bills.

Hey Mr. O., really love your content. You’re the go to channel on down to earth car repair content here on KZbin. I live in Finland, where the whole country’s a big “rust belt” and new cars are taxed so heavily, people rarely buy new ones. So, we’re stuck with old cars and they require a lot of work to keep them running. I drive a Toyota Yaris Verso (Echo in the States, larger model of it) 2000 with the “larger” 1.5 liter engine. I’ve used your videos as reference as well as a reminder that I can do the maintenance and repairs I need myself whenever I can. I’ve saved hundreds in doing the work myself with your help. However, my car’s had the money light on for a couple of years now. It is the treaded P0420 and a new OEM catalytic converter costs more than a the car. I do not know if it is the sensors or if it is the catalytic converter itself, however whenever I take it for the annual inspection (I reset the light just before it), the oxygen levels are high and they measure them from the exhaust. However, the converter seems to work well enough as the other emissions are either 0 or within limits. Where would you start solving the issue and how? I know you might not have the time to answer me, but I appreciate it all the same.

[@anoob4793]

Simply the best channel on KZbin

[@tomcocci]

Thanks for the education. I really appreciate it. I'm basically just a shade tree mechanic that is way behind the times and your videos have helped me immensely.

[@shahislam9450]

Lol its going to tell us if our problem is between point a and point b. It better be because we just poked holes in the wires lol. Best diagnostic KZbin channel

[@charliemagoo7943]

Hey while we're advertising dorman has the repair harness. Then you can do a refresher video this winter

[@apegues]

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

[@marcosmateo8439]

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

[@mike_svt93]

An inexpensive function generator (sine/square/triangle/saw tooth/pulse, etc) can also be used. it's a great way to signal trace and streamline the troubleshooting process.

[@WatchWesWork]

That's pretty slick!

[@dennisbailey4296]

You already have a Signal Generator that works well !!!! I've seen you use it. All the best from Canada

[@kd5ydu]

Very similar to computer repair shops (I work at one) - sometimes you need a tool that costs lots of money but pays for itself because its operator knows how to use it to its full potential. New laptop earlier this year with that ThinkPad and now a new scan tool. I love a good technology refresh - following your channel makes me feel like you're one of my managed IT clients!

[@benkanobe7500]

You are the man! Love the science approach to Auto Mechanics with the skill and experience that only comes from a life under the rack. I wish more Dealers would watch and learn from you as they are just becoming "R&R" men and women. Just remove and replace parts tell the problem goes away then charge the nieve customer.

[@markh.6687]

There was a time that any shop owner or manager catching their people doing that would fire them, as an insult to the profession and damaging the shop's reputation. Few and far between now; knew a retired mechanic that was complaining about the next-gen "technicians" in the late 1980s for the same reason; no diagnostic skills, parts swappers, frequent bring backs he'd have to try to figure out. The guy retired because he was of that age range, and didn't want to go to school anymore for all the onboard electronics. When he complimented me for a suggestion I made while working on my car, I felt very honored. RIP Mike.

[@High_Tech_Mountain]

Someway somehow this one get by me. Great video! Signal generator came in clutch! Thank you for sharing with us!

[@weshawkins7165]

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.

[@craigsmith8217]

You set a standard for all "mechanics". My solution to weird problems has been to trade cars......

[@Dragonborn_1992]

Same code for my family’s 2007 Saturn Aura XR. Just after replacing the front wheel bearings. Same side as well. This video will be interesting that’s for sure.

[@FastX14XE]

These new range of tools have more functionality/useful than the factory tools (within reason), bi-directional controls, wave form generators, being able to select data pids of what you want and it's layed out easily for you . As a main dealer tech I'd kill to have such info at my disposal

[@hddm3]

Awsome Eric! That ultra is really turning out to be very impressive. Thanks for sharing

[@leonardobrien4636]

This is a great function, from one tool.I have a separate signal generator, Which is bulky and needs mains power

[@billrimmer5596]

Excellent! Mains power? UK perhaps? Have a great day.

[@richardostrowski6420]

Another informative video from EricO, great job. That new Autel unit seems like a great kit to have. While using the signal generator to send a signal to the PCM/ECM, you can also verify that the wheel sensor is working by scoping it, scope hooked to sensor and rotate the wheel. Keep them coming, I enjoy each and every one.

[@christiandiaz7422]

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

[@jamesterrill1938]

I am always impressed with your ability. Also impressed with all the wonderful test equipment you have and use. It is not hard for me to realize the huge amount of money you have invested in test equipment and tools.

[@roadmanjim]

Not going to lie: I would love to have lots of shiny toys to do diagnosing with but it's not going to happen. 1) I'm a shade-tree mechanic and spending big bucks on these tools just doesn't make sense FOR ME. It totally make sense for a quality shop to have good tools. 2) My cars don't break that often so a fancy scan tool would just collect alot of dust. Please ignore the haters filled with envy and keep making great videos. Your examples have made me a better mechanic for the little jobs that I do run across.

[@snoopdogie187]

I completely agree. Even with the 4/5 cars and a large van that take care of. Then also doing some outside work, a shiny toy will not be beneficial enough to be a good investment for me. I'm getting by with a Bluetooth OBD reader, which was even enough to work on a MB Sprinter, although it really didn't display anything correctly. But yeah, just seeing this is enough that maybe someone will figure it out. I did the opposite test and look for the signal with a multi-meter at a further up connection.

[@JackdeDuCoeur]

I always learn something from your vids, even the umpteenth brake videos. Nice work. Thanks

[@thegreatjellydoughnu]

That's a pretty slick trick for that kind of diagnostic work. The cool part of you don't want to blow all that money on a fancy tool you can get a signal generator for $100 on the Amazons and that's something I may do to have in the bag of tricks. Thanks Eric

[@jonathonvanmeter4893]

In dialysis. The bio med guy gets a multi meter and a trouble shooting guide! That’s it! Gotta just love the medical practice!

[@TheCrazy243]

Great video, Eric. Learned a lot from you. You gave me confidence for figure it out and you or ScannerDanner (can’t remember) taught me not to be part changer. I am a female mechanic (no ASE) backyard low tech. Not many mechanic in my area aren’t like you at least I know. I met few but they’re not tech, they’re more part changer. Since you self taught. It give me more confidence that I can do it. Just need experience. Expensive tool or not. I love this channel. Ignore these crybaby. Thank you for all you do. I even fixed a small tractor 😁.

[@daveg7878]

Good video to help folks think about the diagnostic process instead of throwing parts at it. Keep 'em coming.

[@gjk1504]

Love the scanner videos. Keep up the great work Eric.

[@TheMasterHackUS]

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

[@kastooMcFry]

I like it. You think like an engineer, Eric. Thanks!

[@alansmith4734]

The difference between Men and Boys, is the price of their Toys! You sir, are 'The Man! Good job!

[@tonyedwin9042]

Keep up the good work ! Some of us do this for a living and benefit from the simplistic pointers you demonstrate . Thanks again
