I've spent the past 2 weeks learning all about the can bus, firmware side, and how to implement it on a microcontroller. The funny thing is that this video about specificially Benz can buses is the best overall general explanation that also goes into the nuances, which is nice because it confirms everything I learned. Seriously. What other video talks about all of this and even dives deep into the electrical schematic but also talks about the firmware, all of that? crazy stuff. Thanks.

[@reverseengineering2943]

Thanks man. Yes, my few years experience of repairing, implementing, and designing CAN buses in cars gave me possibilities to creating this animation. It was specific state of my mind, when I created them.. Also planned making more stuff like this, but lost motivation. Thank you again for this comment, maybe I'll back to this education project in futures. Greetings from Poland!

Beautiful explained thnx

[@tahir1156]

Again thanks and hope for More new technology learning

[@tarekladraa5847]

Thanks a lot, I really learned from you. You are the one.

[@ate1tv368]

A wealth of information, thanks!😊

[@user-du9tn4ci5v]

cool video, nicely done

[@M-Angel25]

Very informative video!!
I have a question... Mercedes O2 sensors receive the signal directly from the ECM or they are connected to a CAN Bus distribution block?

[@reverseengineering2943]

Usually O2 sensor receive the supply directly from ECU and generating signal through heat and amount of oxygen also directly by single wire. Maybe in very new models signal is transmirred via CAN bus, it should be check in mercedes WIS documentation. New Isuzu truck generare lambda signal and transmit them via CAN indeed.

[@M-Angel25]

@@reverseengineering2943 ok. I'm having problems with one o2 sensor and I changed it like 3 times, checked the wires, replaced the ECU and still having the same problem. I was thinking it was a CAN Bus issue so I been watching a lot of videos about this... but I don't know what can be

[@reverseengineering2943]

@@M-Angel25 you have to check wire diagram of your engine electronics system and check from which pins of ECU wires going to O2 sensor plug. Than check continuity of wires using multimeter and if wires is good, repait ECU. No CAN BUS issue.

[@zattut]

Where could Hight and low can bus be in later benz models? Like 2019 a220? The regular obd2 port won't do it. Some say that it has firewall blocking it. Nice video indeed

[@reverseengineering2943]

I think you should check WIS/Stardiagnosis wiring diagrams to understand whole CAN bus architecture. I'm sure obd diagnostic CAN isn't blocked, but with newer standard impemented and you trying to using wrong technology to sniffing them. Everything starting from understand network architekturę and without good documentation it's impossible i think..

I like this

[@RadanZelihmann]

I have one android head unit made by mekede/navifly and i am looking for what Canbus infos they use, that will aloud me to setup into my RealDash app on the head unit. Do you know how can I do that? Since the head unit is already connected to the can, and i don’t want (like the video, exactly the same) to use the original “gauge” app. Can you help me?

[@reverseengineering2943]

I have experience with making android car app connection with VAG group. My android-radio supplier gace my tutorial how to set this unit to different car, but it was around two years ago, so today's units and android systems could be different..

[@wojciechbadek964]

Many computers talking via CAN togheter. Nice description.

How cn i found in my car can bus adapter? W163 ml 55

[@reverseengineering2943]

It depends what you mean 'can bus adapter'. In fact there is No can wires in obd connector (confirmed in 2,7cdi - pin 6 and 14). So I used directly ECU (and all others units) connectors. Most of all CAN buses is connected to EAM / AAM units in late w163 vehicles. So you have to find unit's pinout, i.e. from Stardiagnosis software (star finder), and plug measure needles into unit's connector and needles wiring to CAN-USB adapter, i.e peak, vector, or something cheaper.. then chose proper can speed and recording. That's how I made my sniff.

Hie..my 2001 W203 C320 is cranking but not starting...diagnosis machine showed these faults..
1..B1100 CAN bus engine--can bus off
2..B1102 ..CAN COMMUNICATION ENGINE
3..B1109 CAN communication with Eis faulty..
What do i check or fix..please help

[@reverseengineering2943]

I think one of motorola procesor inside EIS (Electronic Ignition Switch module - key switch) lost eeprom data. But first of all check all fuses and EIS operation - if cannot turn key in ignition switch - it also can by EIS fault reason.

[@BabaDarrel]

Thanx...key is turning freely..starter is running but engine does not start...

[@josephprosper853]

Please Sir, how can I connect with you online for lectures on electrical on mercedez Benz.

These AI channels are beyond annoying and never helpful

[@reverseengineering2943]

This is not AI channel. AI do nothing for creating this animations and videos, all is very hard working and many years experience bro. Stay tuner.
