Fuel Injector Output Voltage Inspection
                               NOTE
    ○Be sure the battery is fully charged.
• Turn the ignition switch off.
• Air Cleaner Housing (see Air Cleaner Housing Re-
  Remove:

     moval(3-54))
•   Disconnect the fuel injector connector and connect the
    measuring adapter [A] between these connectors as
    shown.
     Main Harness [B]
     Fuel Injector #1 [C]
    Special Tool - Measuring Adapter: 57001-1700
• Connect
  leads.
          a digital meter [D] to the measuring adapter

    Fuel Injector Output Voltage
      Connections to Adapter:
        For Fuel Injector #1
          Digital Meter (+) → BK (injector BL/BK)
          Digital Meter (–) → Battery (–) Terminal
        For Fuel Injector #2
          Digital Meter (+) → BK (injector BL/R)
          Digital Meter (–) → Battery (–) Terminal
        For Fuel Injector #3
          Digital Meter (+) → BK (injector BL/O)
          Digital Meter (–) → Battery (–) Terminal
        For Fuel Injector #4
          Digital Meter (+) → BK (injector BL/G)
          Digital Meter (–) → Battery (–) Terminal

• Measure   the output voltage with the engine stopped and
  with the connector joined.
• Slide the engine start/stop switch to run position.
• Turn the ignition switch on.
    Output Voltage
     Standard: Battery Voltage for 3 seconds, and then 0 V

• Turn  the ignition switch off.
  If the reading is in specification, check the ECU for its
    ground and power supply (see ECU Power Supply In-
    spection(3-39)).
    If the ground and power supply are good, replace the
    ECU.
