I was investigating a fault with my VW airbag system today, and I noted the connectors have a really cool safety feature that when they're removed, they short out the airbag igniter pins so you don't accidentally fire them off with static electricity. Very neat. BTW this video has to be the most comprehensive and informative video on car electrics that I've seen, nice work!
I love these start-to-finish videos. The way the information is compiled--it's like reading a textbook, which is amazing. That said, this video should have been twice as long. The information density is such that I felt like I was speed reading. I found myself either rewatching segments or lowering the playback speed and occasionally pausing, just to be able to internalize all that is presented. My brain is strong, but it still needs a second to catch its breath!
I agree 100%. If you see my rough notes when compling this video it was like a textbook....laid out by the 6 segments I sectioned this video into. I was hoping that sectioning it would make it easier to understand but also didn't want to carry the video on to be too long and boring, thus I tried to edit it to be as concise as possible. #informationdensity
@@speedkar99 Thanks for the response. Don't worry about boring! The people who are choosing to watch this type of video are people who are genuinely interested in the material and will only appreciate it. Sections are great for all videos, but are actually even more beneficial the longer a video is. Plus, it's *way* easier to watch a long video on a faster speed than to have to constantly pause a video that's moving along too quickly. (We're used to watching at high speed for creators like South Main Auto already, and it works really well there.) Thanks again!
Lowering playback speed. Now why didn't I think if that? Great idea. I guess this situation is exactly why we have that option! Which then asks the question.....Why is there an option to speed it up? More so, when would you need that??
i've just started out as a car electrician apprentice. it's an amazing job. thank you for great explanations as my mentor barely has time to fully explain things
Bro, this is a masterpiece of a video!! I recently got my first multimeter as I'm determined to understand the electric components part of my car and apply that knowledge to other things. No more expensive electrical repairs when I can diagnose and repair my own electrical problems. Brilliant explanation!! Thank you!!!
TH-cam has become so valuable thanks to the guys like you. I pay ten euros a month to TH-cam and save hundreds of euros on car maintenance. Almost any problem can be resolved on a parking lot if you know the subject.
I love how you don't hang about! TBH, I came here for knowledge not for preamble and requests for likes or subscriptions... You Sir nail it! So much knowledge, given fluidly and freely. Thank you. I hope you are as busy and well rewarded as you deserve to be, I'd bring anything I can't fix to you in a heartbeat! Keep up the content... I obviously subscribed! Lol
You are genius man I thought you only know the mechanical part, But now surprised that you are good in electronics as well, that toothbrush helped you alot you owe it 😀😀
Thanks a lot. You explained it precisely as it should be. I always wanted to know the purpose of those huge bunch of wires in my car. You made my day man.
It's not double sided tape on the ECM. Those are thermally conductive tape to help cool the driver ICs on the board. As you can see, the tape is directly underneath the drivers and contacts the aluminum back plate to act as a heat sink. The white part in the airbag module is not a relay, it's a shock sensor for front collisions. Bose makes the amp, ask them why they use those torx screws. They sell basically the same amp to a bunch of OEMs. Great explanation of the CAN bus basics.
To break down this complex system, you can skip to each of the six topics: 1. Power Distribution 1:04 2. Wiring Harness 5:42 3. Connectors 8:48 4. Electrical Modules 12:20 5. Wiring Diagram 15:25 6. CANBus Communication 20:21
Very nice my man, i worked at a dealer for 10 years and i saw all of this come up. Costumers would ask me all of these questions. Now with You Tube they already have an idea of what does what and why, it could have saved me a lot of explaining. Please keep up the good work it doesn't hurt to share what you know, it helps someone somewhere at some time. Thank you!!
Love you bro...finally I got my dream project video..I am automotive engineer..your all video are very helpful for students as well as professionals... Pls make more video's on ECU software related, autosar,CAN ,LIN, Thanks God bless you
you should buy a used German car (bmw) and you will have to fix it by becoming intimate with all its design bugs. I got a recent E350 with a software controlled alternator, what could go wrong with a Benz, right...? The front main AGM battery sensor (Volt, Amp, Temp) is connected by LIN bus all the way to the rear SAM module in the trunk (instead of front SAM) More than 5 Distinct CAN Buses are inter connected through a GATEWAY Module whos job it is to relay messages across separate networks. Backup Camera software crashes itself on regular basis, causes the Gateway to jam messages and the engine ECU to discharge 90Amp under 11.8V from big AGM battery... that abuse roast all the connectors, then dealer replaces $700 battery without fixing the cheap camera. Great money pit business. Stay away from German money pits, stick with the Lexus refined design version of German chaos. Japanese build cars under license of selected German gear. 👍
cars are so complex that the only way to fix them for profit is by following TSB's or hanging expensive parts until the customer stops coming. Reverse engineering spaghetti CAN Bus design is a true labor of love. The solution in the end is often a module or a simple software update. Benz love frying "SAM Modules" that is the "smart fuse boxes" present in every car based on Robert Bösch goodness.
Crazy tons of information in short amount of time. What about if educations in school could that effective!!! We would be finished in a month. Asking for more videos like this, please :)
I can't thank you enough for the videos you make. They are very informative and clear. And I love the mechanical review series as well. I haven't found a single YT channel that provides this kind of useful content other than yapping about the top speed or horsepower of a vehicle. So thank you very much !
Great video!! I just subscribed to your channel and love all your videos. I have just one little thing to add….Sometimes wires will read the correct voltage using a multi meter, but unable to handle a load due to corrosion or a small break in the circuit, etc. That’s where a nifty tool called a “loadpro” comes in handy. It puts a load on the circuit and you check for voltage drop on your meter. Alot of old school mechanics would use a headlight to load the circuit before loadpro’s became available.
@@speedkar99 yeah, i wanted to repair my laptop instead of getting a new one since it was only 2 years old and expensive, but theres like no information on it and it's a real pain. coming from that to cars is like night and day
You sure have wonderful reference material especially the wiring diagrams. That stuff must cost a fortune. Way back when I fixed cars wiring diagrams were almost useless if they were available at all. The complexity of cars these days is just mind boggling.
Great video! The best lecture I've had on the subject! Subscribed. From my point of view, manufacturers opted for the simplest and cheapest way to control sensors, ignoring out the fact that maintenance and troubleshooting is a nightmare. It would be amazing if they built a serial communication and power bus that ran through the chassis, and have all the sensors be intelligent and connect to this bus, all with the same standardized connector, and a single ecu to manage all modules through software. This way, you wouldn't have a wire harness, and diagnosis & maintenance would be a bliss. However, it would be costly.
Helpful and informative video. 👌 However you might like to search for proper "soldering and joining techniques". Using the "twist, solder and bend" method, while providing a valid connection, creates a parallel bubble with sharp points that may pierce insulation. It also causes a pressure point against other wires in the Harness, and the sharp bend brings a point of future failure due to vibration or movement.
Without a doubt the best high speedkar99 explanation of overly complex automotive electrical systems I have ever watched. Curious as to what your brother does with his day, besides brushing his teeth.
I really like and appreciate what you are doing in this you tube channel. your channel is unique in addressing car issues or information. I will consider this is great service you are doing. Please continue this awesome job. bring some more Car brands under this Mechanical Reviews. Thanks

Love this channel! Even though I have been a mechanic for over 10 years I always learn something new in your videos 😀 cheers from Sweden. P.s is that your brother's tooth brush? 😁
Wow bro.. I've been diagnosing auto electrical for a minute. Your videos are what i would call "essential". How did you learn all this? did you just tear things apart out of curiosity? have you been a mechanic your whole life? curious.
@@speedkar99 dude, are you kidding? I’m subscribed to your channel and am already there! I come to this channel frequently for my entertainment, to actually legit learn stuff, and to watch you destroy your brothers toothbrush and your wife’s T-shirt.
I am a degree qualified electronics engineer with 40 years of experience. DO NOT BAKE A CIRCUIT BOARD IN AN OVEN... You may cause the capacitors to explode. Generally, you will never fix a faulty solder joint that way without killing the rest of the board. If the solder is grey and the joint is poor you may get away with using a heat gun if you are quick and very careful not to overheat the board and surrounding area. The best thing is to use a soldering iron and fresh solder.
Technically the flow of current is from negative to positive, which is why you disconnect the negative terminal on your battery when you're doing electrical work on the car...doing so disconnects the source of the current, namely the negatively charged electrons in the battery. However, since that flow of negatively charged electrons from negative to positive does, in essence, achieve the same result as if positively charged "particles" were flowing from positive to negative, and since it's easier for us humans to think of positive numbers, this is how we choose to refer to current flow. Another interesting fact....the amount of wiring in a car (by weight) has increased from roughly 10lbs in 1970 to 110lbs in a modern car. Whether this is a good thing or not I leave to the reader to decide :)
2nd, plz do a complete video on how to run diagnosis both on new and old cars, read codes, and finally doing away the problem. this was my wish long time ago.
Hi Speedkar99 Team, Thank you so much for your videos. I love the straight to the point clear and concise way you present your videos. I am the favorites subscriber of your channels. Keep all those Automotive electrical and electronic diagnoses and testing support to unknown people in the world.
I bought a 2010 Altima in 2015 30k for a steal with rebuilt title because the harness into ECM behind radiator had a slight crack which was nothing and state farm totaled it. Its been excellent, been changing to CVT fluid now 75k.
The starter on a car is one of the few things that is its own relay, there is +12v going all the time to it direct from the battery, the starter is energized when the solenoid engages the plunger / bendix. Starters simply draw too many amps to run through a relay of the size common in a vehicle.
@@speedkar99 Yes, Honestly, it was best and easiest to understand car electronics and fails diagnostic video I ever watch and was also covering whole electric car course semester. We so appreciate your effort.
