CAUTION:
NOTE:
Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant check, and if nec-
essary, correct the antifreeze concentra-
tion of the coolant.

Use only distilled water. However, if dis-
tilled water is not available, soft water may
be used.

If coolant comes into contact with painted
surfaces, immediately wash them with wa-
ter.

Do not mix different types of antifreeze.

CHECKING AND CHARGING THE BATTERY
CHK
ADJ
Measure the open-circuit
voltage prior to charging.
Connect a charged and
AMP meter to the battery
and start charging.
Make sure that the current
is higher than the standard
charging current written on
the battery.
By turning the charging
voltage adjust dial, set the
charging voltage at 20
24 V.
Adjust the voltage so that the
current is at the standard
charging level.Monitor the amperage for
3
5 minutes to check if the
standard charging current is
reached.
Set the time according to the
charging time suitable for the
open-circuit voltage.
Refer to “Battery condition
checking steps”.If the current does not
exceed the standard
charging current after 5
minutes, replace the battery.
If charging requires more than 5 hours, it is advisable to check the
charging current after a lapse of 5 hours. If there is any change in the
amperage, readjust the voltage to obtain the standard charging
current.
Measure the battery open-circuit voltage after leaving the battery
unused for more than 30 minutes.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.YES NO
YES
NONOTE:
Voltage should be measured 30
minutes after the machine is stopped.
NOTE:
Set the charging voltage at 16
17 V.
(If the setting is lower, charging will be
insufficient. If too high, the battery will
be over-charged.)

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.

The engine trouble warning light comes on for 1.4 seconds after the main switch has been turned “ON”
and when the start switch is being pushed. If the warning light does not come on under these condi-
tions, the warning light bulb may be defective.

SUBSTITUTE CHARACTERISTICS OPERATION CONTROL (FAIL-SAFE ACTION)
If the ECU detects an abnormal signal from a sensor while the vehicle is being driven, the ECU illumi-
nates the engine trouble warning light and provides the engine with alternate operating instructions
that are appropriate for the type of malfunction.
When an abnormal signal is received from a sensor, the ECU processes the specified values that are
programmed for each sensor in order to provide the engine with alternate operating instructions that
enable the engine to continue to operate or stop operating, depending on the conditions.
The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribed value,
and the other in which the ECU directly operates an actuator. Details on the fail-safe actions are given
in the table below.
