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.

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!

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. 👍
@glasser28194 жыл бұрын
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.

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.

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.

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.

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.

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.

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 :)

You know electrical systems must be complex when GM service technicians can't read a schematic in the service manual to know that the malfunctioning power mirrors are not controlled by the body control module. True story; power mirrors didn't work on my Traverse, fuse was blown. Not only could the tech not identify the correct fuse and said the fuse was good, but then he was trying to tell me it's problem with the body control module after they looked at it for 2 days. I took it back, diagnosed it myself in 20 minutes armed with the factory service manual, a 9 volt battery, and some clip leads. Fuse blew because the mirror switch had a contact break off inside, which short circuited the power supply. Unplugged the switch, verified I had 12 volts with the blown fuse replaced. Took the 9 volt battery and energized the up/down and left/right circuits to the motors in the mirrors, and they worked fine. New switch for $20 off Amazon, and good as new. That dealer did not get a good review.
