NOTE:Odometer, tripmeter, and stopwatch modes
Push the “SELECT” button to switch the display
between the odometer mode “ODO”, the trip-
meter modes “TRIP A” and “TRIP B” and the
stopwatch mode in the following order:
TRIP A TRIP B ODO Stopwatch
TRIP A
If the fuel level warning light comes on, the
odometer display will automatically change to
the fuel reserve tripmeter mode ”F-TRIP” and
start counting the distance traveled from that
point. In that case, push the ”SELECT” button to
switch the display between the various tripme-
ter, odometer, and stopwatch modes in the fol-
lowing order:
F-TRIP Stopwatch TRIP A TRIP B
ODO F-TRIP
To reset a tripmeter, select it by pushing the “SE-
LECT” button, and then push the “RESET” button
for at least one second. If you do not reset the fuel
reserve tripmeter manually, it will reset itself auto-
matically and the display will return to the prior
mode after refueling and traveling 5 km (3 mi).
Stopwatch mode
Standard measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “SELECT” button to stop the stopwatch.
3. Push the “SELECT” button again to reset the stopwatch.
Split-time measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “RESET” button to measure split-times. (The colon “:” will start flashing.)
3. Push the “RESET” button to display the final split-time or push the “SELECT” button to stop the stop-
watch and display total elapsed time.
4. Push the “SELECT” button to reset the stopwatch.
Coolant temperature display
The coolant temperature display indicates the temperature of the coolant. Push the “RESET” button to
switch the coolant temperature display to the air intake temperature display.
When the coolant temperature display is selected, “C” is displayed before the coolant temperature.
Air intake temperature display
The air intake temperature display indicates the temperature of the air drawn into the air filter case. Push
the “RESET” button to switch the coolant temperature display to the air intake temperature display.
Even if the air intake temperature is set to be displayed, the coolant temperature warning light comes
on when the engine overheats.
When the key is turned to “ON”, the coolant temperature is automatically displayed, even if the air
intake temperature was displayed prior to turning the key to “OFF”.
When the air intake temperature display is selected, “A” is displayed before thetemperature.

NOTE: Self-diagnosis devices
The model is equipped with a self-diagnosis device for various electrical circuits. If any of those circuits
are defective, the engine trouble warning light will come on, and then the right display will indicate a
two-digit error code (e.g.,11,12,13).
Display brightness and shift timing indicator light control mode
This mode cycles through five control functions, allowing you to make the following settings in the order
listed below.
Display brightness:
This function allows you to adjust the brightness of the displays and tachometer to suit the outside
lighting conditions.
Shift timing indicator light activity:
This function allows you to choose whether or not the indicator light should be activated and whether
it should flash or stay on when activated.
Shift timing indicator light activation:
This function allows you to select the engine speed at which the indicator light will be activated.
Shift timing indicator light deactivation:
This function allows you to select the engine speed at which the indicator light will be deactivated.
Shift timing indicator light brightness:
This function allows you to adjust the brightness of the indicator light to suit your preference.
To make any settings in this mode, you have to cycle through all of its functions. However, if the key is
turned to “OFF” or the engine is started before completing the procedure, only the settings made be-
fore the “SELECT” button was last pushed will be applied.
In this mode, the right display shows the current setting for each function (except the shift timing indi-
cator light activity function).
To adjust the brightness of the multifunction meter displays and tachometer
1. Turn the key to “OFF”.
2. Push and hold the “SELECT” button.
3. Turn the key to “ON”, and then release the “SELECT” button after five seconds.
4. Push the “RESET” button to select the desired brightness level.
5. Push the “SELECT” button to confirm the selected brightness level. The control mode changes to
the shift timing indicator light activity function.
To set the shift timing indicator light activity function
1. Push the “RESET” button to select one of the following indicator light activity settings:
The indicator light will stay on when activated. (This setting is selected when the indicator light stays
on.)
The indicator light will flash when activated. (This setting is selected when the indicator light flashes
four times per second.)
The indicator light is deactivated; in other words, it will not come on or flash. (This setting is selected
when the indicator light flashes once every two seconds.)
2. Push the ”SELECT” button to confirm the selected indicator light activity. The control mode changes
to the shift timing indicator light activation function.

ECU’S SELF-DIAGNOSTIC FUNCTION
The ECU is equipped with a self-diagnostic function in order to ensure that the engine control system is
operating normally. If this function detects a malfunction in the system, it immediately operates the en-
gine under substitute characteristics and illuminates the engine trouble warning light to alert the rider
that a malfunction has occurred in the system. Once a malfunction has been detected, a fault code is
stored in the memory of the ECU.
To inform the rider that the fuel injection system is not functioning, the engine trouble warning light
flashes when the start switch is being pushed to start the engine.
If a malfunction is detected in the system by the self-diagnostic function, this mode provides an ap-
propriate substitute characteristic operation, and alerts the rider of the detected malfunction by illumi-
nating an engine trouble warning light.
After the engine has been stopped, the fault code number appears from the lowest value in order of
precedence on the LCD meter. Once a fault code has been displayed, it remains stored in the memory
of the ECU until it is deleted.

gine stop switch to “OFF”.
2. Disconnect the wire harness coupler from
the fuel pump.
3. Simultaneously press and hold the “SE-
LECT” and “RESET” buttons, turn the main
switch to “ON”, and continue to press the but-
tons for 8 seconds or more.
All displays on the meter disappear except the
clock and tripmeter displays.

4. Press the “SELECT” button to select the CO
adjustment mode “Co” or the diagnostic
mode “dIAG”.
5. After selecting “dIAG”, simultaneously press
the “SELECT” and “RESET” buttons for 2 se-
conds or more to execute the selection.
6. Select the diagnostic code number that ap-
plies to the item that was verified with the
fault code number by pressing the “SELECT”
and “RESET” buttons.
The diagnostic code number appears on the
LCD meter (01-70).
To decrease the selected diagnostic code
number, press the “RESET” button. Press the
“RESET” button for 1 second or longer to auto-
matically decrease the diagnostic code num-
bers.

Check the intake air temperature and coolant temperature as close as possible to the intake air tem-
perature sensor and the coolant temperature sensor respectively.
If it is not possible to check it with an atmospheric pressure gauge, judge it by using 101.3 kPa as the
standard.
If it is not possible to check the intake air temperature, use the ambient temperature as reference.
