Harley-Davidson Serial Data waveforms

Post by michael.galvin$ » Tue Jan 01, 2019 5:23 am

I am trying to locate good and bad Serial Data waveforms, this bike is a 2009 Harley but I believe most of the Harleys of that era had a single line network and later went to Can Bus twisted 2 wire system. Any help appreciated. Mike

Hi Mike,

Think this might be a little tricky!! I've managed to find a few wiring diagrams online and like you said it appears to be a single wire that links the ECU's together. I've had a look on the waveform library and unfortunately there are none there for networks. I will put the post onto the our Facebook group and see if we have any luck there.

It might be worth just grabbing some data from the Bike and posting here so we can take a look though. It may be that it is a similar to an existing network we are familiar with. What are the symptoms with the Bike?

Kind regards
