Specification Desc./Quantity
Deleting errors By pressing the 'enter' button, the stored errors (MEM) become
part of the historical data (STO). The next time Axone is con-
nected to the ECU, the errors in the historical record (STO) will
no longer be displayed
Coil The coil is activated five times
Outlet valve The solenoid valve is activated five times
Intake air solenoid valve The solenoid valve is activated five times
Rpm indicator The needle should be at 10000 rpm for two seconds
Speed gauge Activates the speedometer at 100 km / h

Desc./Quantity
EEPROM : checksum error. Signal not valid Control unit internal error
Data zone EEPROM not valid : default values reset Control unit internal error
Crankshaft position sensor Circuit open An interruption has been detected between pin 9 and pin 3 of
the small connector in the control unit
Crankshaft position sensor Shorted to ground Continuity has been detected between the ground connection
and pin 9
Crankshaft position sensor Signal not valid Abnormal voltage has been detected due to an electric resist-
ance not foreseen in the circuit connecting to the revolution
sensor: between pin 9 and pin 3 of the small connector of the
control unit
Ignition capacitor Shorted to ground Error detected in the capacitor charging system in the control
unit: check that the power supply and ground connection of the
control unit are adequate
Ignition coil (circuit open) Lack of ground connection to pin 14 has been detected
No ignition Error detected in the capacitor charging system in the control
unit: check that the power supply and ground connection of the
control unit are adequate
No ignition Error detected in the capacitor charging system in the control
unit: check that the power supply and ground connection of the
control unit are adequate
Incorrect crankshaft signal. Signal not valid Abnormal error detected by the control unit
