INSPECTION PROCEDURE

Note

Be careful of flames.

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (FUEL METER OPERATION)


    1. Use the Active Test to check the operation of the fuel receiver gauge Click here.

      Combination Meter
      Tester Display Test Part Control Range Diagnostic Note
      Fuel Meter Operation Fuel receiver gauge OFF, Sender E, Empty, Warning, 1/4, 1/2, 3/4, Full or Sender F -
      OK
      Fuel receiver gauge is normal.

    NG
    OK
  2. READ VALUE USING GTS (FUEL INPUT)


    1. Use the Data List to check if the fuel receiver gauge is operating properly Click here.

      Combination Meter
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Fuel Input Fuel input signal/Min.: 0, Max. 127.5 Current fuel level displayed Unit: Liters.
      OK
      Fuel amount value displayed on the GTS is almost the same as needle indication.

    NG
    OK
  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FRONT FUEL MAIN AND RETURN TUBE SUB-ASSEMBLY)


    1. Disconnect the H20 combination meter assembly connector.

    2. Disconnect the h1*1 or h2*2 front fuel main and return tube sub-assembly connector.


      • *1: Engine Type Diesel

      • *2: Engine Type Gasoline

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Engine Type Diesel
      Tester Connection Condition Specified Condition
      H20-33 (FUEL) - h1-2 Always Below 1 Ω
      H20-34 (E2) - h1-3
      H20-33 (FUEL) or h1-2 - Body ground Always 10 kΩ or higher
      H20-34 (E2) or h1-3 - Body ground
      Engine Type Gasoline
      Tester Connection Condition Specified Condition
      H20-33 (FUEL) - h1-2 Always Below 1 Ω
      H20-34 (E2) - h1-3
      H20-33 (FUEL) or h1-2 - Body ground Always 10 kΩ or higher
      H20-34 (E2) or h1-3 - Body ground

    NG
    OK
  4. INSPECT FRONT FUEL MAIN AND RETURN TUBE SUB-ASSEMBLY


    1. A01BG09E11

      Remove the front fuel main and return tube sub-assembly.


    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      A-2 - B-2 Always Below 1 Ω
      A-3 - B-1


    NG
    OK
  5. INSPECT FUEL SENDER GAGE ASSEMBLY


    1. A01BCR7E01
      Text in Illustration
      *a F (Upper)
      *b E (Lower)

      Remove the fuel sender gauge assembly.


    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 13.5 to 16.5 Ω
      Float level is E (lower) 405.5 to 414.5 Ω
