PROCEDURE


  1. READ VALUE USING GTS (FUEL INPUT)


    1. Using the GTS, read the Data List Click here.

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

    OK

  2. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY AND BODY GROUND)


    1. Disconnect the D66 combination meter assembly connector.

    2. Disconnect the G24 fuel suction with pump and gauge tube assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D66-16 (L) - G24-2 (FS) Always Below 1 Ω
      D66-15 (E) - G24-3 (FE) Always Below 1 Ω
      D66-21 (ET) - Body ground Always Below 1 Ω
      D66-16 (L) or G24-2 (FS) - Body ground Always 10 kΩ or higher
      D66-15 (E) or G24-3 (FE) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT FUEL SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY
