Ferrari F1 team cleared of using coded pitboard message...Whiting made clear during a press briefing held in Melbourne prior to the race that all messages would either be heard or seen, and anything deemed to be coded would certainly be looked into.
Under normal circumstances the message would not be one the FIA would allow, but Autosport can confirm Ferrari has provided the FIA with an entirely satisfactory explanation.
During the race a number of teams had problems with fuel recalculations in the wake of the 20-minute red flag stoppage following McLaren driver Fernando Alonso's violent accident on lap 17.
Whiting confirmed to Autosport after the race the red flag and restart raised "a number of glitches" that needed to be solved.
For Ferrari, and Vettel in particular, it led to a problem with how the SECU (standard electronics control unit) software handled the stoppage, necessitating the pitboard message at the time.
The FIA therefore concluded the message was permissible and will not take any action.
