INSPECTION PROCEDURE

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (FUEL SENDER GAUGE)


    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 sender gauge (main) input signal/Min.: 0, Max.: 127.5 Fuel sender input value Unit: L
      OK
      Fuel amount value displayed on the intelligent tester is almost the same as needle indication.

    NG

    1. Disconnect the D66 meter connector.

    2. Disconnect the G24 gauge connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D66-37 (L) - G24-2 (FS) Always Below 1 Ω
      D66-24 (E) - G24-3 (FE)
      D66-21 (ET) - Body ground
      D66-37 (L) or G24-2 (FS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR
