Well if there are now no logged codes, it doesn't sound like the light is coming on for an electrical fault as such. Without plugging it in to ET, it is difficult to say though.
One thing I have noticed is that "the hydraulic oil must be warmed to a temperature of 50 to 60c in order to perform submodes 15, 16 and 17" Now it's feasible that the software could put the light on and refuse to calibrate if the oil is too cold, but I cant find it documented anywhere in SIS. It may be your problem though.
