In this video I explain what is the CAN-BUS, I explain different types of CAN bus including C-CAN (Powertrain CAN), M-CAN (Multimedia CAN) and B-CAN (Body CAN), I explain where you can find the CAN-BUS on the car, how control units are connected to CAN-BUS, I explain what the Gateway is, I also show you on the car how to check the CAN-BUS resistance, how to check the CAN-BUS voltage (with a multimeter), how to check the CAN-BUS for short to ground. I also show you how to read the CAN-BUS waveform using a picoscope.

Thank you so much, I have always wondered how the can bus works exactly. Keep up the good work! And also now I understand why the ford focus of my sister in law was acting up with weird and seemingly unrelated error codes when the solder joints of her cluster broke.

I was hoping that you might have an example of a failure or what really happens when one of these modules is bringing down the can and how you find out which one that is. I did need this though as i have very limited knowledge on a can bus system and working with electrical problems on a vehicle this could be helpful.

  • I tested according to what I see in your video but I do not see what happens if there is a short to power. When ohm testing 6 to 14 with the key off I get OL. Voltage on pin 6 is 10v and voltage on pin 14 is 8v. The van will not crank or start. The scantool can only communicate with modules on the low speed bus. It cannot communicate with ecm or tcm which are where the resistors are. I would suspect there is a short to power in one of the modules correct?

    @lucasellyson6872@lucasellyson68726 ай бұрын

    • Hi there, thanks for the comment. There was no fuse issue because battery voltage is not provided directly to the CAN-Bus, so there is no fuse for the network, as voltage is provided through the CAN-Controllers inside the control units. So that short to ground will be detected by the CAN-Controllers and will change the mode to limp-home mode.

  • I understand your talking automotive but in semis they use several datalinks and terminating resistors are inside of either a module or a starpoint. Example being on a New Cascadia on the powertrain CAN the terminating resistors are located within the CPC and the ACM. Within the PT CAN the MCM is part of the datalink but does not contain a terminating resistor. This is true for both Detroit and Cummins as far as my experience has shown me.

    @nickschuster7618@nickschuster76182 ай бұрын

    • Hi there, thanks for sharing your experience. Different companies tend to put the terminating resistors in different locations. Most of the times one of them is inside the ECM, and the other one could be inside any unit on CAN-Bus. For example I’ve seen the second resistor inside the BCM, Instrument cluster, interior fuse box and on some models I’ve seen an external terminating resistor as well.

  • Please elaborate on the voltage on CAN HI and CAN LO. What is your reference? Are you measuring the voltage between the two CAN wires or are you measuring from the CAN wires to frame ground? Also, where does the power originate from to provide the voltage changes? Does each module require a 12 volt line and a ground for power?

    @TexasEngineer@TexasEngineer6 ай бұрын

    • Hi there, voltage comes from each control unit as each unit connected to the CAN-Bus has got a CAN controller inside which regulates the BUS voltage and convert the signals to the CAN message format. For measuring the voltage on CAN-Hi, voltmeter red prob on CAN-Hi wire/pin, and black prob on body ground. Same way for CAN-Low but this time red prob on CAN-Low wire/pin. Ignition switch also must be on.

    @hareethasrini41@hareethasrini412 ай бұрын

    • Hi there. Normally gateway is connected between two different types of network. If you have multiple units connected to two CAN-Bus, that one which must be on the car in any circumstances is the gateway. For example, smart key control module is not a gateway as you may have a car without smart key. But instrument cluster is a must on the car. Also, workshop manual can help for finding the gateways.

    @charleslyell3748@charleslyell37485 ай бұрын

    • Hi there, thanks for the great question. In each CAN data frame, there are multiple fields, the second one is called “arbitration field” which decides the message priority. So if two control units are sending messages at a very same time, arbitration field decides which one has a higher priority. Therefore, the message with the highest priority will be sent first.

  • HI there, congratulations this is one of the better CAN bus videos. If I can respectfully suggest something that you could clarify: you explained the gateway module purpose and that terminating resisitors. However, given that both the Nav-AV Modcule and the AC Module (M-Can) are connecteed to C Can, you did not make clear how to determine which module of the two is the Gateway. You simply just stated that it was the AC module. Same for the Smart Key Module and the Instrument Cluster (B-CAN).They are both also both connected to the C-CAN. How do you know that the IC is the Gateway. How do you determine that just be looking at the wiring diagram. Yes I understand you could unplug modules until you see 120ohms on the meter, but that is a very long way around requiring often a lot of work. thanks again.

  • Well..If terminating Resistance is Inside ECU, doesnt it disrupt CAN communication when we remove ECU from the vehicle? But as we can see CAN system still works after Removing ECU?

    @dhruvsingh2876@dhruvsingh2876Ай бұрын

    • Hi my friend. CAN BUS is a multi-master network, so, removing a unit should not disrupt the entire network (although I have seen some cases that it does 😒). Anyway, removing the ECM or even a terminating resistor (in case of having an external resistor) will only make the network more noise sensitive and voltage fluctuation will put the other control units at risk, but network must still work.

    • As far as I remember, J533 is the CAN gateway integrated with instrument cluster. So not a bad idea to check it out.

    • When you calculate the total resistance, as I explained in the video, the result was 1/R(total)=1/60 so as we want to calculate the R total, we change both sides of the formula to bring the R total and 60 to the top, so the result would be R total=60.
