CHECKING THE PURGE CUT VALVE
SOLENOID
1. Check:
• Purge cut valve solenoid resistance
Out of specification
→
Replace.
a. Disconnect the purge cut valve solenoid
coupler from the wire harness.
b. Connect the digital circuit tester to the
purge cut valve solenoid terminals as
shown.
c. Measure the purge cut valve solenoid resis-
tance.

CHECKING THE WHEEL SWITCH
1. Check:
• Wheel switch “1” output voltage
Out of specification
→
Replace the right han-
dlebar switch.
a. Connect the digital circuit tester (DC V) to
the handlebar switch coupler (right) as
shown.
b. Turn the main switch to “ON”.
c. When turning the wheel switch in direction
“a” and “b”, check that the output voltage is
within the specified values.
d. Connect the digital circuit tester (DC V) to
the handlebar switch coupler (right) as
shown.
e. When turning the wheel switch in direction
“a”, check that the output voltage is within
the specified values.
f. When turning the wheel switch in direction
“b”, check that the output voltage is within
the specified values.
