2007 Mercedes Benz Communications Issues
Very good stuff... I wish some of the shops I visit could try this reasoning... just once.... Thanks for the info..
Thank you Bernie. Good job. Have a blessed and safe week to you and your family.
I hope you went out and played the lottery that night Bernie. An easy module to access and it happened to be the one you decided to grab signals from and it was the problem module. Powerball should be no match for you.
Great video. A logical, step by step approach coupled with knowledge of the circuits makes it seem easy.
Bernie, Always Well Done ! Please Correct me if I am thinking incorrectly. CAN B corrupted the data for CAN C through the interface module? Thank You for leading and sharing this information to better our industry.!!!
Rick The CAN C Bus is working normally, but the CAN B bus is down. The CAN C bus is expecting data transmissions from the CAN B bus, however the CAN B bus is down. Therefore the data is not received by the CAN C Bus. In this condition the CAN C module will set DTC's for the missing information.
Yes that is my understanding. The C Bus is working . The scan data is corrupt or or faulty for C Bus communication due to the B Bus fault. The DLC layout wiring and reporting strategy to the scan tool is the reason. Thanks for the reassurance. This strategy information is so critical for all of us.
Good stuff Bernie. You must stop teaching people this stuff. I will be out of a job soon. Just kidding of course. The techs that need this aren't watching anyway. Was that a genuine xentry or a "off shore?" Just curious. I have an off shore that I use regularly. Surprised you didn't use the pico. Again just kidding. Wish I had your scope in my arsenal.

I ALWAYS learn something new when i watch or attend your classes. Thank you!
Thanks Bernie for a great presentation! One comment - you often refer to the High Speed CAN bus as CAN Hi. This can be misleading because it's easily confused with the CAN Hi wire (vs. the CAN Lo wire) when you're actually referring to the High Speed CAN bus and not specifically the CAN Hi wire in the High Speed CAN bus. At least I think that's what you mean! Or maybe I'm just confused?
Really enjoy these Bernie, thank you.
