(b) Inspect the combination meter assembly speed input signal
1
Inspect voltage
Hold the front wheels up
Push the shift lever to NEUTRAL
Turn the ignition switch to ON
Slowly turn the front wheel, measure the voltage between terminal A9 and A11
Standard voltage is as follows:
Voltage changes alternately
Result and solution:
Normal Replace the combination meter assembly
If abnormal, inspect the speed sensor
