Great video. Very informative. Thank you

Cool. It is my understanding that the CAN+/- resistance reading is 60ohm when all the modules are asleep. It then goes open loop on the meter when modules wake up and communicate.

Thank you! Trying to teach myself these new network systems. I work on scissor lifts/booms, telehandlers and they are starting to use these type of systems on them 😅 and I like to work on my own car repairs since I have a shop so gotta learn it eventually.

The connections were fine for the can bus . What you are seeing in inherent to GM can bus . There was something you had mentioned , and I do not mean ot offend , but it was incorrect. You had said that the modules send out the signal on can bus , but then moved back to a correction inadvertently when mentioning that the can bus is wired in parallel. But back to something more important as a tip you can teach your students , if you are questioning the validity of the signal on your scope channels while scoping can bus , simply revert to using 1 channel lead using pin 14 as your ground for that channel and pin 6 as your positive acquisition. By doing so you will now see what the computer sees. The waveform will look perfect if all is well. Think about why that would be before you teach it to them though 😉. Oh and don't forget that the ohm test will soon be gone from dlc and in some cases already is thanks to gateway modules. Some networks use a terminating resistor in each and every module on the bus like VW as well.

Do you know if Chrysler LIN can be monitored at the OBD port? I don't see a LIN connection at OBD port pinouts. Perhaps it's translated and put in with the other BUS signals?

@AdamsAnalysis

I am not familiar with the system. I would have to look at a diagram. As you guessed, it most likely exists behind a gateway module. To gain a waveform you would need to make a connection at the gateway side of the LIN or another connector/module on the network.

I looked over the OBD port pinout top to bottom front and back for the vehicle (07-11 Chrysler Sebring/Avenger/Caliber) and I don't see anything related to LIN. Just seam's strange to me they would have a network on the vehicle that cant be accessed from the OBD port.

hiii..what is the difference between k line and lin bus??? is k line just for diagnostic purpose or does it connect different modules for communication???? plzzz suggest????

Hello, thankyou for the upload. In a Porsche car I can see that there are 2 k lines, these k lines are going to many control units. One connects to engine cu, transmission cu & alarm. Other k line goes to AC, parking cu, radio etc . There is also CAN wire that goes to all control unit but it does not go to obd connection. The 2 k lines goes to pin 3 & 7 of obd plug connection. What do you think is it ok to assume that k line is being used only for diagnosis process & CAN only for communication? Yhankyou

@AdamsAnalysis

Жыл бұрын

Without looking at the specific application, I would agree. In many vehicles, the diagnostic communication is a single route to a gateway module. If you're up against a U code, review the enabling criteria for the code and begin checking the specific network for that fault. In the case of CAN, check the general integrity of the network by first measuring the terminating resistors. If the network is beyond a gateway, be careful about how you enter the circuit for a measurement, such as a backprobe.

I use one of these break out boxes , but how ironic is it that pico scope test leads dont fit because the box uses unshielded 4mm banana sockets compared to the shielded 4mm banana plug test leads.

I do not have an easy way to check for sure. I would imagine most Launch/Autel or SnapOn branded tools, with the right Subaru software would be able to complete a service procedure like that. A rep for one of those companies should be able to find out.

Hi Adam, I have an error link when i try to scan my honda civic ex coupe. I probe it and saw on a straight line 9 volt dc and no waveform when ignition key on. I don't know my car must have a waveform the same or likely as your 2001 Missan Quest. I you address that for me, thanks. I don't have resource to find that information.

do you have any info you can e mail me on using a BOB in diagnosing/ troubleshooting? i am new to using a bob and like to get some good info on testing network faults.

Question about a break out box. Do they work on a network with a gateway module? I have watched your videos and it seems to me they can only read between the DTC and the gateway. Does the gateway pass through or does it act as a firewall?

@AdamsAnalysis

7 ай бұрын

The breakout box will not provide a lot of information when a vehicle utilizes a gateway module. As you said, it will only provide that line between the DLC and gateway. When a gateway is present, you have to find an alternate location to gain access to the network you're needing to assess.

Looks like the baud rate wasn't correct for the data. Will look like garbage if you don't have the correct sample rate. Not sure if the obd connector has a clk (clock) line. That's used to provide the correct sample timing for serial communication.

Is the Data Bus Diagnostic Tool will really tell us the main fault of the LAN?

@AdamsAnalysis

It's a great tool that can help add information during diagnosis. It may not tell you exactly what is wrong, but it is quick to turn on and will provide direction.

which software do you use in network testing?

@AdamsAnalysis

Primarily PicoScope to look for the profile of the waveform. Some OE tools have additional software to help ping modules and check for responses.

Hello it is possible to send me to pdf of k line communition,. Tanks

Caution: Wait for the bus to go to sleep before attempting to measure the resistance of the terminating resistors! The sample rate was set too low resulting in “aliasing”of the signal.

If a module is not working, will your BOB tell you which one or will it tell you where any problem is located?? Your dirty signal is from your BOB. I do not believe is the money it costs for one of these tools for as little as it does and the labeled information does not match every vehicle for every protocol, I would build my own without the Christmas lights. The DLC is very accessible to get all this info without the need for a BOB. There is typically an accessible module to get the waveforms and resistance value from also, such as the ABS module. I liked the video overall, thanks.

@AdamsAnalysis

3 жыл бұрын

Thanks for watching! The BOB itself cannot provide much information, such as which module is at fault. It is just providing a point of access electrically to the network. The most powerful reason to use one is to reduce the risks associated with back probing a connector, disconnecting a connector or stabbing a wire to gain a signal. More and more manufactures are telling us not to disconnect connectors due to terminal tension issues.
