Did you ever resolve this....? I have a similar code... I believe it may be related to throttle position or connectivity...?

So good news, I bypassed the fuel pump controller using the workaround described here:
http://www.motorcycleinfo.co.uk/index074c.html?fa=contentGeneric.nvxszdkebklxuaer&pageId=428065

I can hear the fuel pump running now but engine is still not firing....
New error code is:
21F850 : Electric fuel pump (fuel system), signal or value below threshold Currently present : NO Engine warning light (MIL) : NO Frequency count : 4
Logistic(Healing) count : 40
..Fault Code History :
....Record number : 1
....Odometer : 16047.0 km
....ABS time : 355762
....Fuel pump Voltage : 12.20 V
....Fuel Pressure : 1007.40 mBar
....Engine Speed : 413.0 rpm
....Throttle-valve angle based on DK-stop : 18.48 %

Any ideas.....?

Thanks

I only received this code once. Afterwards, the fuel pump failed and had to be replaced. The service tech did not get this code, or any code dealing with the fuel pump. The pump was removed and tested. It was dead.
