Welcome to the site, I'm new here myself, but have found that there is alot of good information for Ferrari owners evrywhere.
I have no experience with F1 gearboxes, but I do know that sometimes computers can get confused. The fuse may have had something to do with this.
Reseting the computer might rid the problem. Usually this is done by disconnecting the battery for a given amount of time. 10 minutes is usually enough, although I can't be for sure with this model. The owners manual should have this information, or you can wait for someone to post on here who knows more about this model than I do.
If you do decide to disconnect the battery, remember that you always disconnect the ground side first to avoid shock. I don't know what country you are from so I can't tell you if that is black, (green is also a common ground color) or red because some countries have the polarity reversed on all electrical devises. Refer to your owner's manual to find out which color is ground, which is likely to be black ( in most parts of the world, positive flows to the negative, which is why positive is red, to represent that it is "hot", although in some countries, this is reversed)
Be careful! ...and I hope you get back on the road soon. Cheers!
