- Speed sensor output voltage
Out of specification → Replace.
Output voltage reading cycle: 0.6 V to 4.8 V to 0.6 V to 4.8 V
a. Connect the pocket tester (DC 20 V) to the speed sensor coupler (wire harness side) as shown.
Pocket tester: 90890-03112.
Analog pocket tester: YU-03112-C.
Positive tester probe: White/Yellow «1»
Negative tester probe: Black/Blue «2»
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 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.
