I had similar issues with mine around the 600 mile make. I would get TC Failure and the TC Light would come on as well as Engine Management Light. Took to local dealer HTM Motorcycles. They had it for a few days and it turned out to be Firmware between the 2 ECU units, but they had to get their laptop updated by Husqvarna for it to load the correct firmware.
Almost 3000 miles on the clock now and never had an issue since 🙂
