FUEL INJECTION SYSTEM

09

Fuel system voltage 
(battery voltage)

Displays the fuel system voltage (battery voltage).
Engine stop switch is on.

0 ~ 18.7 V
Normally, approximately 12.0 V

20

Sidestand switch

Displays that the switch is ON or OFF.

Stand retracted: ON
Stand extended: OFF

30

Ignition coil

When the engine stop switch is turned from OFF to 
ON, the ignition coil is actuated five times per sec-
ond and the engine trouble warning light comes on.
• Connect an ignition checker.
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check that spark is generated, 
5 times with the engine stop switch 
ON.

36

Fuel injector

When the engine stop switch is turned from OFF to 
ON, the fuel injector is actuated five times per sec-
ond and the engine trouble warning light comes on.
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check the operating sound of the fuel 
injector five times with engine stop 
switch ON.

50

Fuel injection system 
relay

When the engine stop switch is turned from OFF to 
ON, the fuel injection system relay is actuated five 
times per second and the engine trouble warning 
light comes on (the light is OFF when the relay is 
ON, and the light is ON when the relay is OFF).
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check the fuel injection system relay 
operating sound 5 times with the 
engine stop switch ON.

51

Radiator fan motor relay

When the engine stop switch is turned from OFF to 
ON, the radiator fan motor relay is actuated five 
times every 5 seconds and the engine trouble warn-
ing light comes on. (ON 2 seconds, OFF 3 seconds)
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check the radiator fan motor relay 
operating sound 5 times with the 
engine stop switch ON.
(At that time, the fan motor rotates.)

52

Headlight relay 1

When the engine stop switch is turned from OFF to 
ON, the headlight relay is actuated five times every 
5 seconds and the engine trouble warning light 
comes on. (ON 2 seconds, OFF 3 seconds)
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check the headlight relay operating 
sound 5 times with the engine stop 
switch ON.
(At that time, the headlight turns ON.)

54

ISC (idle speed control) 
valve

When the engine stop switch is turned from OFF to 
ON, the ISC (idle speed control) valve fully closes, 
and then it opens until it is at the standby opening 
position when the engine is started. This operation 
takes approximately 12 seconds until it is com-
pleted.
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

The ISC (idle speed control) valve 
unit vibrates when the ISC (idle speed 
control) valve operates.

Grip warmer relay

When the engine stop switch is turned from OFF to 
ON, the grip warmer relay is actuated and the 
engine trouble warning light comes on. (the light is 
OFF when the relay is OFF, and the light is ON 
when the relay is ON).
• If the engine stop switch is ON, turn it OFF, and 

then turn it back ON.

Check the grip warmer relay operat-
ing sound 1 time with the engine stop 
switch ON.

60

EEPROM fault code dis-
play

• Transmits the abnormal portion of the data in the 

EEPROM that has been detected as a fault code 
44.

• If multiple malfunctions have been detected, differ-

ent codes are displayed at 2-second intervals, and 
this process is repeated.

01 CO adjustment value is detected.
03 Code re-registering key (immobi-
lizer) is detected.
04 Throttle valve fully closed notifica-
tion value is detected.
(00) Displays when there is no mal-
function.
