Furthermore, JAUH is right, ISIS it's 3422, but this kind of error exist sometime in the CMS.
However, starting again from this fault messasge,ISIS (22FN-10FC) SPEED OR MACH FUNCTION, with the red flag on the ISIS (I assume) it's lead me again to check the Stby Pitot Probe failure (9DA1, 9DA2, 9DA3)!
As the first fault recorded its also Pitot probe (341115), I would suspect severe icing (this only engage myself). When I mean Severe, I mean really severe, kind of Iceberg flying at FL 350
