After the last step above, the autopilot will display “S_C”, meaning it is
checking the directions to where the rudder is being driven. Then it will be
displayed “S_L”, while the rudder is driven to its limits twice. At this stage, the
rudder is driven hard over shortly, in order to define the limits.
When the limits are defined, the autopilot goes back to set mode automatically.
If any error occurs during this process, a code described on the table below is
displayed:
