ambient temperature.
When engine is hot: Displays
ambient temperature 20 °C
(68 °F).

Display
Check with throttle valve fully
closed.
Turn and hold the main
switch in the "
tion, then press the accelera-
tor pedal. (If the display value
changes, the performance is
OK.)
Compare the actually mea-
sured intake air temperature
with the indicated value.
Compare the actually mea-
sured coolant temperature
with the indicated value.
Check that the number in-
creases when the rear
wheels are rotated. The
number is cumulative and
does not reset each time the
wheel is stopped.
Remove the lean angle sen-
sor and incline it more than
65 degrees.
Turn the main switch to "
(on), and then compare the
actually measured battery
voltage with the display val-
ue. (If the actually measured
battery voltage is low, re-
charge the battery.)
Shift the transmission.
