b. Set the main switch to “ON”.
c. Elevate the rear wheel and slowly rotate it.
d. Measure the voltage (DC 5 V) of White/Yel-
low and Black/Blue. With each full rotation
of the rear wheel, the voltage reading
should cycle from 0.6 V to 4.8 V to 0.6 V to
4.8 V.

CHECKING THE COOLANT TEMPERATURE
SENSOR
1. Remove:
• Coolant temperature sensor
WARNING
EWA14130
• Handle the coolant temperature sensor
with special care.
• Never subject the coolant temperature
sensor to strong shocks. If the coolant
temperature sensor is dropped, replace it.
2. Check:
• Coolant temperature sensor resistance
Out of specification → Replace.

a. Connect the pocket tester (Ω × 100) to the
coolant temperature sensor “1” as shown.
b. Immerse the coolant temperature sensor in
a container filled with coolant “2”.
NOTE:
Make sure the coolant temperature sensor ter-
minals do not get wet.
c. Place a thermometer “3” in the coolant.
d. Slowly heat the coolant, and then let it cool
to the specified temperature indicated in
the table.
