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

    NG
