Checking method
01
Throttle angle
Check for changes in dis-
played values while open-
ing and closing the throttle.
• Fully closed position
14–20
• Fully opened position
97–107
03
Intake air pressure
Displays the intake air pres-
sure.
Operate the throttle while
pushing the start switch
“
”. (If the display value
changes, the performance
is OK.)
05
Intake air temperature
Displays the intake air tem-
perature.
Compare the actually mea-
sured air temperature with
the display value.
06
Coolant temperature
Displays the coolant temper-
ature.
Compare the actually mea-
sured coolant temperature
with the meter display val-
ue.
08
Lean angle sensor
Remove the lean angle
sensor and incline it more
than 65 degrees.
• Upright
0.4–1.4
• Overturned
3.8–4.2
09
Fuel system voltage
(battery voltage)
Approximately 12.0
Compare with the actually
measured battery voltage.
(If the battery voltage is
lower, perform recharging.)
07
Vehicle speed pulse
0-999
Check that the number
increase when the front
wheel is rotated. The number
is cumulative and does not
reset each. time the wheel is
stopped.
44
Error is detected while
reading or writing on
EEPROM.
• Malfunction in ECU. (The CO adjustment
value and throttle valve fully closed notifica-
tion valve are not properly written on or
read from the internal memory.)
60
46
Power supply to the fuel in-
jection system is not normal.
• Malfunction in the charging system. Refer
to “CHARGING SYSTEM” & check rectifier

Faulty ECU memory.
(When this malfunction is
detected in the ECU, the
fault code number might
not appear on the LCD of
the FI diagnostic tool.)
• Malfunction in ECU. (The program and data
are not properly written on or read from the
internal memory.)
