Excellent job explaining a LIN bus with terms and analogies that the majority of American technicians can easily identify with. Great verbal communication about a mirror that had a "failure to communicate." Thanks Dan!

[@billbyrd9845]

For a long time, I skipped over your videos thinking they were over my head. In reality, they are just what I need. You really break it down for me. Thank you so much!

[@lesrogers7310]

Wow...who knew a 'simple' mirror could have so many electrical connections. I've learned something new today and that is what I always try to do....even at almost 60. Thank you Dan.

"who knew a 'simple' mirror could have so many electrical connections" => Everyone on track with automotive development (tracking the features creeping into mirrors over time) and being able to read a wiring diagram. 🙂

[@letsdrive3943]

This video is awesome!!! I was trying to code the mirrors to work with my comfort access system in my mini r60 and I got a notice saying that the only way would work is if the mirrors were connected to the l i n system. So I wanted to educate myself on what Lin was thank you for the very informative video

[@Diagnosedan]

😊👍

[@windward2818]

The motivation for LIN was the basic challenge of replacing the seemingly ever increasing number of wires (and subsequently the size of the connectors which also costs money) to save weight, complexity, the wiring itself, with a low cost solution that allowed expandability (vehicle build features or options) without needing to install, and logistically support, several different wiring harnesses. The wiring harness would remain the same, with only the node functionality changing. To minimize the cost (and size) of a node was a huge challenge in overall architecture and led to the creation of a smart node. Basically a single IC that provided all of the electronics to run the node, which included the bus interface and decode (performed in a dedicated state machine and not firmware, at least for the dumbest nodes) the power supply, inputs and power outputs to control the loads. The reason LIN is not as "robust" as CAN, as stated in the video, is cost. The question posed to the engineers developing LIN was; what is the minimum number of wires to support a low cost node. The answer, as you can see in the video, is three; Power, Ground and LIN. I lot of work went into LIN, both in engineering approach and in demonstrating a basic feature set a minimum cost. A lot of OEMs did not immediately understand that the benefits of LIN actually pay for themselves, until studies where undertaken to understand all the actual costs of each feature and feature option (or potential upgrade after delivery) which was steadily increasing, and was needed for the OEM to stay competitive in the market place. One difficult cost to quantify, and that had much higher assembly costs than first thought, was the process of installing wiring harnesses and how the grater the size of the harness the much greater the time it took to install correctly. Handling large harnesses during production is very difficult and labor intensive. When wiring harnesses reach a certain diameter (many wires in the harness) they become almost impossible to route quickly, a lot of force is needed to place and bend the harness into a channel or clip. Another cost that was not usually included at first glance by the OEM at the system level was the cost savings in smaller connectors and connector pins (reliable connector pins are expensive), which can cost more than the wire itself depending on wire length. The system approach to LIN actually was taking shape as CAN was being more widely adopted and becoming less expensive. So what you find many times is an automobile architecture that uses CAN for latency (communication speed) and LIN for cost. For example, if we look at a door node, from a latency standpoint CAN makes sense for communication from the door to the body control module, so coming to the door you would see 4 wires; Power, Ground, CAN High and CAN Low. Form the door main CAN node (perhaps located in the door switch panel) to the other door control and features you will communicate using LIN with 3 wires; Power, Ground and LIN. For a generic dumb LIN node, the IC operates in a standard way (both for communication and control) and does not need to be programmed (the program is hard-wired in the device), which lowers the overall development cost. It is not like a traditional module where you have to write and install firmware (software). However, even the programming LIN nodes have dropped so much in price that it is now an option, but at a higher cost.

[@spelunkerd]

I'm one of those guys who is binge watching your old videos. Classic, great teaching! I find the videos are a little easier to listen at 1.25 replay speed. It makes sense that the LIN bus is slower and less reliable, with only one wire rather than two so less ability to screen noise. Interestingly, on boats a completely different communication system is in use, with the ability for scanners to read complex signals rather than simply 1s and zeros on the general party line.

[@apegues]

Yeah, I had the same problem changing the spark plugs on my diesel

Such a shame I can't warrant spending money on expensive tools anymore for example oscilloscope so I can just practice with new testing methods and unsure if the cheaper hantek versions are woth buying and which I should buy. Any help would be vastly appreciated. Keep up the good work Dan your an inspiration to the motor trade.

[@glasser2819]

Thanks Dan for showing the LIN Bus . The funy thing is that amazing mirror with so much complexity failed because of water intrusion in a cheap connector. The functional complexity is super well designed but the basic quality was left out ... for some reason. It sure takes a smart engineer to troubleshoot how all these inter-networked bus systems fail. The real-deal will be field troubleshooting with 3G connected cars...

[@Diagnosedan]

🤣🤣🤣👍

[@koeniglicher]

It's not the whole mirror that failed. It's this one wiring terminal in a connector on the wiring harness inside this driver mirror assembly as a consequence of likely water input. So, this mirror would not have to be exchanged. Just this wire terminal would have to be fixed and seals checked and likely replaced.

[@tricky778]

That camera is a fisheye camera which can actually see a little bit behind itself. If you look at the tiny spot in the very centre you can see it almost any angle you can look from. If you can see that spot, the camera can see your eye. As you move your eye to the edge and even beyond the edge, the spot moves towards the edge and the black circle around that spot distorts into a strange squashed ellipse as it also moves to the edge - one side of the circle is compressed into the vanishing space between the spot and the edge of the lens while the other side of the circle is compressed into the still large space between the spot and the front convex surface of the lens.
