is informed via a pop-up message on the display. The
fault codes are listed in the diagnostics menu; active
fault codes are at the top of the list and are denoted by
a green dot. For more detailed information regarding
the cause and remedies, use the arrow buttons to scroll

provide information about the number of engine hours
when the fault became active and the SPN and FMI

Erasing fault codes
The memory of the diagnostic function is reset when

check if there are any malfunctions in the system. If so
a new fault codes is registered.
