What were you doing before the code showed up?

U0156 Lost Communication

Have you checked your connectors and wires for broken wires or loose connectors.?

Why, did you make a change to the bike? Try reflashing the map again.

You keep giving short answers. I was trying to help figure out what led up to the code.

Now you say that Harley an ECM update. I'll bet that there was a reason for that too. But I'm going away.

I had my bike in the dealers to fit an engine accent kit.They did an oil service by mistake and ran an update which is what they usually do on a service.I then had to come back another day to get the engine accent kit fitted.

Loading the stock map seems to have cleared the issue.The code is gone and the bike starts fine.
