Method
To determine if the controller is correctly rec-
ognizing the speed sensor signal, rotate the
wheel to which the speed sensor is connected
and make sure that the number of rotations of
the wheel indicated matches the actual num ber
of rotations.
1. Go into speed sensor diagnosis mode.
See "Operating Procedures to Diagnosis
Mode".
Confirm that the assist mode display is flash-
ing "HIGH" rapidly (0.2 second).
2. When you raise and rotate the wheel (with
the speed sensor), the rotation number dis-
play 1 on the display unit will change.
Before rotating the wheel (with the speed
sensor), "0" will be displayed on the rotation
number display 1 of the display unit.
When you rotate the wheel (with the speed
sensor) 1 time, "1" will be displayed on the
rotation number display 1 of the display unit.
When you rotate the wheel (with the speed
sensor) 12 times, "12" will be displayed on
the rotation number display 1 of the display
unit. When you rotate the wheel (with the
speed sensor) 13 times, the display of the ro-
tation number display 1 of the display unit will
return to "1".
Thereafter, each time the wheel (with the
speed sensor) is rotated, the number of rota-
tions display 1 on the display unit will be from
"1" to "12".
TIP
• You should at least rotate the wheel (with the
speed sensor) 3 times and make sure that "3"
is displayed.
• If the speed sensor malfunctions, the number
of rotations displayed on the display unit will
increase before the wheel (with the speed
sensor) is rotated even once, or the number
will not increase even when the wheel (with
the speed sensor) is rotated once (or there is
a delay in the increase in the value).
