I very much need your experience about CAN bus. My bike (Ducati) got a serious problem about CAN bus. The first time, my bike shows the "CAN line" error, dead totally on the street.
I found the CAN IC in the dashboard was faulty, so I replaced it, and the bike lived again. I started the crank, engine running about one day, then the error "CAN line" came again!
Then I replaced CAN IC again. This time the engine was running about 5 minutes and the error appeared again! I checked wire loom, and all of them were fine. No shorted, no problem.
Someone told me about the ignition coils destroying my dashboard by EMI/ESD/EMF.
