Item Meter display Procedure
01 Throttle position sensor sig-
nal
• Fully closed position 11–21 Check with throttle valves
fully closed.
• Fully open position 96–106 (1XB1, 1XB5, 1XB6)
58–68 (1XB2, 1XB7, 1XB8)
Check with throttle valves
fully open.
03 Intake air pressure Displays the intake air pres-
sure.
Operate the throttle while
pushing the “ ” side of the
start/engine stop switch. (If
the display value changes,
the performance 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 Rear wheel vehicle speed
pulses
Rear wheel speed 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
65 degrees.
• Upright 0.4–1.4
• Overturned 3.7–4.4
09 Fuel system voltage
(battery voltage)
Approximately 12.0 Set the start/engine stop
switch to “ ”, and then com-
pare the actually measured
battery voltage with the
meter display value. (If the
actually measured battery
voltage is low, recharge the
battery.)
