Procedure
01
Throttle position sensor sig-
nal
• Fully closed position
14–20
Check with throttle valves
fully closed.
• Fully open position
97–107
Check with throttle valves
fully open.
03
Intake air pressure
Displays the intake air pres-
sure.
Set the engine stop switch to
“
”, and then operate the
throttle while pushing the
start switch “
”. (If the dis-
play value changes, the per-
formance is OK.)
05
Air temperature
Displays the air temperature. Compare the actually mea-
sured air temperature with
the meter display value.
06
Coolant temperature
When engine is cold: Dis-
plays temperature closer to
air temperature.
When engine is hot: Displays
current coolant temperature.
Compare the actually mea-
sured coolant temperature
with the meter display value.
07
Speed sensor pulses
Speed sensor pulse
0–999
Check that the number in-
creases when the rear wheel
is rotated. The number is cu-
mulative and does not reset
each time the wheel is
stopped.
08
Lean angle sensor
Lean angle sensor output
voltage
Remove the lean angle sen-
sor and incline it more than
45 degrees.
• Upright
0.4–1.4
• Overturned
3.7–4.4
09
Fuel system voltage
(battery voltage)
Approximately 12.0
Set the engine stop switch to
“
”, and then compare the
actually measured battery
voltage with the meter dis-
play value. (If the actually
measured battery voltage is
low, recharge the battery.)
Fault code No.
