Sadly some idiot at the design stage never thought that the battery on an adventure bike might go flat, or be disconnected.
This means that if the voltage drops too far, or you remove one of the cables to fit something like a GPS power lead, the [SERVICE] warning come up. What's even more stupid is that they can only reset for a set period, so it will then come on at the wrong time or milage, and you have to monitor your milage 'manually' which defeats the point of having it there in the first place!
