Right, back to this one.
Got the bike to the dealers yesterday, they did a check using the scanalyzer

, no other codes present other than the code 16 - battery voltage. Mechanic checked the battery, was putting out about 13 -13.5 volts, revved the bike, voltage output rose steadily

. Checked other possibilities, but came up with nowt. Cleared the code from the memory.
According to the manual he said it could be a loose or dodgy connection, checked all connections that he could & these were double checked by the chief mechanic as well. Didn't want to start stripping off the tank to check connectors in there, as this would start to cost me time & money

.
The bike has performed as usual with no other probs at all. So here's hoping everything is aok.
