Great video Steve I love how you explained this. Now people will understand that mechanics do not have a magic computer that just tells us what it is gonna take to fix the vehicle.
Great video/tips. A note about the third misconception: It does not apply to some select brands like Mercedes Benz SCN as programming for the ecu can be done directly from scantool without needing the OE software. You'd still need a expensive scantool with a J2534 vci.
I dont know nor work on cars vut this video was great! Cool! Awesome review of the tools and best of all, of the knowledge to be a mechanic to fix things. You showed that the tools are great mostly if you are a mechanic and the tool will give you hints as to where the problem is but not fix it for you. Thank you for sharing!
If you want to know how to use a scantool, look at the channels of e.g. Rainman Ray, or O’Rileys mobile mechanic. My favorites on YT. Almost never does the scantool tell what should be rectified, they use it to find readings (diagnose) which are different, and then solve the problem. Especially Jimmy (O’Riley) uses this very well when diagnosing DPF issues.
Jimmy O’Riley has educated a lot of us here in the UK & a lot of other mechanics have taken offence to his truthfulness on how things are done , tuff titty I’m afraid as without people like Jimmy we’d be stuck & out of pocket by rip off garages, right to self repair I’m a big supporter of 👌
One thing you did not mention that you do need an upper end scan tool 4. That thing is to reset the timer in the ECU. Chrysler motors will go into limp mode. Which will keep you from driving your vehicle if it senses a problem that has persisted for too long of a time. Mechanics do not tell you this. They Immediately tell you you need very expensive parts even transmissions or engines. What needs to be done. When your vehicle it's stuck in second gear, Is to reset the timer in the ECU. And repair the next fault code that comes up or chase it down which could be as simple as low transmission fluid or a faulty speed sensor. So buying a high qualityl bi -directional scan tool is almost a must with ownership of newer vehicles. Otherwise you're throwing money away because mechanics are not going to be honest with you.
Great video, the tech repair and tool costs are getting crazy - very good points about diagnostic scanner expectations it seems the vehicle manufactures are making things deliberately difficult a bit like HP with their printers the money is in the ink sales not the printer itself. Aside from the ECU back to basics is a logical way of tackling most issues and of course a few parts. spending on parts that may or may not be defective like a MAF or injectors on a high mileage vehicle isn't IMHO lost or wasted money it's building in reliability....
I purchased one of the more expensive Autel Scanners and could not detect 2 items stop/start battery issues and front or rear locker light. So I tried my friend Snap-on Apolo D9 and same issue. My Jeep Wrangler Rubicon was my first item to try and fix. Ended up replacing both batteries and this solved the problem. 2 issue- rear or front locker. Ended up buying Z bypass kit. This also solved the problem. I spoke to a friend that is shop foreman at a Jeep Dealership and problems such as these can only be found using factory equipment. Also he conneted their equipment and the system passed. We disconnected the bypass kit and found no problem with the lockers. His dealer usually drain and flushes out and debris!!! I admit, scanners have come a long way, but with all the new electronics most scanners are 1-2 years behind. Yanni
The cost of these new scanners is just too expensive for a guy who may actually need it a few times in their life. Plus subscription fees? then if you need to change a computer part you need another very expensive tool to program it to your car. The more computerized these cars become the less repairable to the average joe they become and the more they seem to break down. I kind of miss the older days of points , condenser and a strobe light to adjust timing.
Scan tools are just a tool that assists in diagnosing or can assist in confirming a diagnosis such as isolating a evap leak. I use the live data more than anything because it helps you trace down issues. Some vehicles have some overly generous sensor ranges so your vehicle drives like crap but no codes. The live data can show you the parameters the sensor is operating at, but you need to know what’s ideal and also what affects that sensors reading as well. Scan tools are not a magic bullet, but they sure as hell beat tracing wires for voltage ranges all day!😂😂😂😂
So what ended up being the actual mechanical issue that was causing low compression on that one cylinder? I'm wondering if the other bidders ended up being right to pass on it 🙃
@@nowayjose596 the exhaust follower on cylinder number six went bad and fell out. It also ruined that lobe of the camshaft. I had to replace the camshaft and that follower. The repair cost me less than $500.
@ Wow that sucks. Even simple wired scantools can do this. And I hope the Bluetooth dongle isn’t the reason the feature not being present. If it is, I hope Thinkcar can release an updated Bluetooth dongle for a fair price so we don’t have to worry about draining the battery while we work.
Your Video is misleading. I have a Launch scanner which is currently around $589. It does a lot if you know how to read the data. It does program, if you are talking about configuration programming. I replaced many ABS modules and the Launch copies conf from old module and to the new module. And it was a used module. The Launch will aso do the initial configuration on transmissions and hvac module. Resets on other modules. So my Launch can do programming, it just doesn't do flash updates or flash programming on brand new modules. If you have transmission rebuilt and they use the same TCM built into the transmission, you won't need any programming. if you replace a transmission with a brand new transmission from GM, that will have ro be flash programed and the scanner will not do this part. But you can rent a RAP from Dorman and program it. RAP remote access programming. So a scanner does programming and configuration or setup, but doesn't do flash programming. Im sure it you have a relative compression issue that is a real compression problem, you would eventually see a code. But since you had no codes, this does not mean the scan tool won't tell you what's wrong or which cylinder is misfiring. There is also mode 6 you can see misfires and also Launch shows you cylinder balance which is a graph and the lines drop low on the cylinders which are not contributing. Code or not the scanner works! Besides, setting codes is part of the diagnostic software of the module, not the scan tool. Has nothing todo with the scanner! You also need to understand long term and short term fuel trims. This can tell you if you have vacuum leak, or the engine is running rich or lean, and which bank or cylinders are affected. Fuel trims can also point you to a bad A/F or O2 sensor. Which you can view the O2 sensor voltages too and graph them. Now the PCM will not set a code if the ECT sensor is reading in range. If the range is -40F to 285F. If you unplug the ECT or have a broken wire or bad connection somewhere, it will read -40F which is in range and may not set a code, it's in range and doesn't know rhe wire is broken. But you know by looking at the PID, so the scanner does diagnose this problem! Did you know that -40F is the same as -40 celcius. If you have an engine running slightly rich and no code set, you can also view the MAF sensor reading to see if your MAF is over reporting the amount of air going into the engine. The scanner does this, so just because it don't show a MAF sensor code does not mean the scanner can't do this. What aftermarket scanners do not do is everything. No scanner can do everything on all car. Only the factory scan tools which only work on certain makes and certain models can do almost everything. Most scanners don't come with a scope, but I never used a scope and I fixes every car I came in contanct with 100% diagnosed guaranteed. In the past 15 years at least. Now there were times I wish I had a scope, but it wasn't absolutely necessary. Most scan tools don't do this. There are limitations with all scan tools, but to claim it don't work on this or that because you can't translate the data, doesn't mean it's not working. It's working!
@@mcplutt It's about 3 years old, Launch x431 Pros mini. It's small and sucks really, but still works. They have 10 inch screen scanners on sale ever so often for around $912. I've used the Snap-on scanners and they not any better. The latest Zeus+ is also a $100 per month subscription if you want updates and everything to work. Ridiculously priced and more often than not I had to grab the Launch.
This might be helpful for a beginner diy person. But, by the time a diy'er is ready to spend $500 + on a scan tool they're aware of their limitations and are simply looking for more information or functionality.

Hi I'm new to your channel. Just happen to stumble upon it whilst scrolling TH-cam for some answer about my own car issue. Any advice or knowledge you can give me would be much appreciated help. I have a 2011 mercedes c class 2.1 diesel auto. My engine management light sometimes comes on and with my cheap crappy little diagnostic scanner it tells me there is a high performance can bus issue. Now and again it will also say lost communication with the tcu. It drives absolutely fine but when this light comes on it can cause my gear changes to go awful. I can clear the gearbox tcu fault and drive the car fine again but it will not let me clear the can bus issue. It's a permanent fault code. Is there a way the canbus could be causing this issue? Is my 1st question. Or do I have 2 faults? 2nd is there a cheap way I can find and scan or check the can bus? Thanks in advance if your willing to help me out 👍🏻
In most cases, CAN communication issues result from a bad connection in the network wires. Usually corrosion in a connector, or a broken wire. Unfortunately, the only way to visually see the activity on those wires is by using an oscilloscope. You’ll find two wires for these networks, they’ll each vary the voltage by one volt very quickly. An example would be one wire will switch from 2.5 to 1.5 volts and the other will switch from 2.5 to 3.5 volts. These oscillations will be hundreds of times per second. Not typically a DIY diagnosis, but that’s up to you.
Scanners do very... yet there is scanners or aka obd2 diagnostic tool.. My maximums 4.0 and 5.0 scanners work great and I never had problems with reading codes even on cars or HD trucks or motorcycles that both scanners can do.
One of my biggest problems today is that all information is organized by code. No codes, no diagnostic tree. Usually I know what the problem is, but not why the computer is reacting improperly to the inputs. I usually spend hours reading and searching for information on how a program makes decisions and how systems work and mostly not finding anything useful. My biggest problem is what I know gets in the way of learning that it doesn't work that way anymore or on this particular system. Everything today seems backwards of what it used to be.
You’re right. A lot of programming seems irrational when inputs are out of range. I have noticed though, that the latest cars are much better at identifying the probable cause than they used to be.
@ToolDemos Actually, I'm referring to in range issues. Most common is the computer reacting opposite of expected response. Finding what overrides expected response is difficult. Example is O2 rich and computer reacting by adding up to max fuel. Some programs appear to disregard O2 input after other conditions are seen, even if not currently existing.
@@jeffhill3681 oh, I see. So, the PCM would rank one input higher than another and add fuel, even when O2s are screaming not to. Very interesting, haven’t seen that yet. I can imagine how frustrating that is.
@@michealcannizzo100 The biggest difference is that the pro3 Ace is newer and has the new DBSCar VII connector. That will allow you to communicate on CAN FD networks and do DolP sessions online.
After some services or repairs, the vehicle’s control module needs to be reset or recalibrated. Like oil life reset, battery registration, or zero point reset on an accelerometer. They all get lumped into that category.
what do yo mean by "do airbags". yes they can read airbag codes?, but if the airbags have deployed, you cannot replace the bags then reset the airbag computer. that needs to be replaced or reprogrammed along with replacing the seatbelts. if you just have a faulty sensor, replacing the sensor and clearing the codes work
You are 100 % wrong about the PCM programming. For an average guy they wouldn't know the right source and how to trick the unit, if you are very familiar with backdoor entry, you will be able to reprogram the unit.

You buy the tool for where you at as you grow so you move up the line of scan tools you don't buy the heavy artillery and never use most of it it's simply a waste of money which you will never get back
Every experienced mechanic knows that scanners dont tell u what the problem is. U have to know what the scanner is telling u and then know what to do with that info.
It actually resets the monitors to not ready when you clear codes. Obviously it can say they are ready , only a drive cycle can do that. Otherwise it would defeat emissions testing. Although that might actually work on a vw computer and scanner lol.
Not sure which scan tool you're talking about but it's not that one. I do recall there being some low end tools which allow you to pay per brand, however. Launch may very well make one.

I get that every day people are like just hook it up to the scanner lol.
Very common misconception.
You buy the tool for where you at as you grow so you move up the line of scan tools you don't buy the heavy artillery and never use most of it it's simply a waste of money which you will never get back
eSCAN ELITE, Mode 6
Don't be a parts changer like this guy he doesn't understand what he's talking about either
indeed 😅
As a workshop manager in a Bosch car service, I can say that a lot of information on TH-cam is incorrect.
Every experienced mechanic knows that scanners dont tell u what the problem is. U have to know what the scanner is telling u and then know what to do with that info.
💯
@@ToolDemos I see a red mark but I can not make out what it is.
Scanner wont attempt a fail in changing a oiil filter😂
but you did use the scanner to help you
Absolutely. Couldn’t diagnose much of anything without it.
Kingbolen is made by launch
Yeah, it is. I think they call it white labeling.
You forgot number five it can not reset readiness monitors that are not set that you have to do a complete drive cycle 😂😂
It actually resets the monitors to not ready when you clear codes. Obviously it can say they are ready , only a drive cycle can do that. Otherwise it would defeat emissions testing. Although that might actually work on a vw computer and scanner lol.
You don't need a subscription to program
Lmao The Launch can do all functions AFTER you pay $40-$100 per function per car...
Strange, I've never experienced that.
Not sure which scan tool you're talking about but it's not that one. I do recall there being some low end tools which allow you to pay per brand, however. Launch may very well make one.
Mmmmmm.......very disappointed with my Launch not being able to do what it is said to be able to do. Software issues. Stay away
You wamt courant buy a bunch of selenoid 😂
