Diagnosis Function (Status Checking Function)
(1) Function
To help users with troubleshooting and maintenance, sensor output display
and actuator operation are made possible without the use of special tools or
measuring instruments.
(2) Procedure
• Transfer to diagnostic mode as follows:
• Hold down "RESET" and "SELECT" buttons on meter and turn on the main
switch. Continue holding the buttons down, until "F0" appears on meter.
• When "F0" appears on meter, press "SELECT" to switch to "DIAG" and confirm
by simultaneously pressing down "SELECT" and "RESET" buttons.
• Using "RESET" or "SELECT", switch to destination diagnostic code.
(3) Operation
The following describes the operation of each diagnostic code in ECU.
* NOTE: Remove the fuel pump coupler while codes 36 to 39 are in
operation to prevent fuel from being injected.
Code selected Item Description
01 Throttle sensor
• Displays throttle sensor input value in angle.
• Fully closed throttle "15 to 18" degrees, fully open throttle
approx. "95" degrees.
02 Atmospheric pressure sensor
• Displays atmospheric pressure in Kpa.
• Approx. "101" Kpa at normal altitudes.
03 Intake pressure sensor
• Displays intake vacuum in Kpa.
• Displays atmospheric pressure when crankshaft is at rest.
• Less than atmospheric pressure during starting motor cranking.
05 Intake temp. sensor • Displays sensor-detected temp. in °C.
06 Water temp. sensor • Displays sensor-detected temp. in °C.
07 Vehicle speed sensor • Displays integrating number of sensor detected pulses.
08 Overturn sensor
• Displays sensor output voltage.
Erected "0.4 to 1.4" V
Overturned "3.7 to 4.4" V
Line broken "5.0" V
09 Monitor voltage
• Displays battery voltage when engine switch is turned on.
• Approx. "12" V when engine is at rest.
20 Shifter switch
• Displays state of speed shift switch in ON/OFF.
ON: Shift switch is on.
OFF: Shift switch is off.
21 Select switch
• Displays state of select switch in ON/OFF.
ON: SB (selects MAP in Super Bike specification.)
OFF: ST (selects MAP in Stock Sports specification.)
