    METER REFERENCE

    Item Test Details Diagnostic Note
    FUEL GAUGE OFF, EMPTY, 1/2, FULL -

    OK: 

    Needle indication is normal. 

    NG: REPLACE COMBINATION METER ASSEMBLY 

    OK: GO TO NEXT STEP 

  2. READ VALUE OF INTELLIGENT TESTER 
    1. Operate the intelligent tester according to the steps on the display and select the "DATA LIST".

    METER: 

    METER REFERENCE

    Item Measurement Item / Display (Range) Normal Condition Diagnostic Note
    FUEL GAUGE Fuel input signal Min.: 0, max.: 255 Fuel gauge indicates (F): 35
    Fuel gauge indicates (3/4): 85
    Fuel gauge indicates (1/2): 145
    Fuel gauge indicates (1/4): 186
    Fuel gauge indicates (E): 205    		 -

    OK: 

    Fuel value signal displayed on the tester is almost the same as needle indication. 

    NG: REPLACE COMBINATION METER ASSEMBLY 

    OK: GO TO NEXT STEP 

  3. INSPECT FUEL SENDER GAUGE ASSEMBLY 
    1. Disconnect the L8 connector.
    2. Disconnect the fuel sender gauge connector.
    3. Remove the fuel sender gauge assembly.
    4. Measure the resistance between the terminal 2 (EF) and 3 (FS) of connector according to the value(s) in the table below
