I guess whilst on tour Chris you didn't have access to Protune to check out fault code. Did you get opportunity to check it out when you got home

Not aware of any simple portable plug-in to view fault codes being a bespoke USB access system. Thankfully there is now an internationally adopted CANBUS standard for motorcycles using a 6 pin OBD2 diagnostic port for which an adaptor lead is required to allow use of 16 pin car type scanner systems.
