record of mal-
functionsThe condition code of any fixed mal-
function is recorded in the ROM and
displayed by the tachometer. Refer
to the condition code list in “USER
MODE” for details on the condition
codes.Condition codes 11
– 44
30 ROM (Clearing
the condition
code record)Selecting this diagnosis code clears
the condition code record of mal-
functions stored in the ROM.
If an error has occurred in a sensor
signal, it was recorded in the ROM
and the tachometer displays 10,000
r/min. If no error has occurred, the
tachometer displays 0 r/min.
CO, diagnosis switch box method
Press the UP switch eight times
within four seconds to clear the con-
dition code record from the ROM.
Test coupler adapter method
Remove the rear cowling.
Disconnect the relay unit coupler
from the relay unit.
Press the start switch ten times
within four seconds to clear the con-
dition code record from the ROM.0 r/min (no error) or
