    Do not remove ETV actuator in the gear case [A]
    since it has been set with precision at the factory.

ETV Actuator Input Voltage Inspection
                             NOTE
    ○Be sure the battery is fully charged.
• Turn the ignition switch off.
• Air Cleaner Housing (see Air Cleaner Housing Re-

    Special Tool - Measuring Adapter: 57001-1700
• Connect
  leads.
          a digital meter [D] to the measuring adapter

    ETV Actuator Input Voltage
      Connections to Adapter:
        Digital Meter (+) → R (actuator W/R)
        Digital Meter (–) → BK (actuator BK/R)

• Measure   the input voltage with the engine stopped with
  the connector joined.
• Turn the ignition switch on.
    Input Voltage
      Standard: About DC 1  2 V or –1  –2 V

• Turn  the ignition switch off.
  If the reading is out of the standard, check the following
    items.
      ETV Actuator Relay (see ETV Actuator Relay Inspec-
      tion(17-77))
