INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST BY INTELLIGENT TESTER

  1. Operate the intelligent tester according to the display and select the "Active Test".

    Combination meter:

    Item
    		Test Details
    		Diagnostic Note
    Fuel Meter Operation
    		EMPTY, 1/2, FULL
    		-

    OK:
    Needle indication is normal.



NG
REPLACE COMBINATION METER
OK


2.READ VALUE OF INTELLIGENT TESTER

  1. Operate the intelligent tester according to the display and select the "Data List".

    Combination meter:

    Item
    		Measurement Item/Range (Display)
    		Normal Condition
    		Diagnostic Note
    Fuel Input
    		Fuel input signal/ Min.: 0, Max.: 255
    		Fuel gauge indicates (F): 47
    Fuel gauge indicates (3/4): 92
    Fuel gauge indicates (1/2): 148
    Fuel gauge indicates (1/4): 187
    Fuel gauge indicates (E): 205
    		-

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

3.INSPECT FUEL SENDER GAUGE ASSEMBLY (MAIN)


    E108387E10

  1. Measure the voltage of the wire harness side connector.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    V9-2 - V9-3
    		Engine switch on (ACC) or on (IG)
    		10 to 14 V

  1. Remove the fuel sender gauge assembly.

  1. Connect the fuel sender gauge connector.



    E108386E03

  1. Check that the float position is between E and F.

  1. Measure the resistance between the terminals 2 and 1 of connector of the connector.

    Standard resistance:
    Float level
    		Float Position
    		Specified Condition
    F
    		51.4 to 57.4 mm (2.02 to 2.26 in.)
    		6.5 to 8.5 Ω
    E
    		121.7 to 127.7 mm (4.79 to 5.03 in.)
    		237.6 to 242.6 Ω

4.INSPECT FUEL SENDER GAUGE ASSEMBLY (SUB)


    E108387E11

  1. Measure the voltage of the wire harness side connector.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    W11-2 - W11-3
    		Engine switch on (ACC) or on (IG)
    		10 to 14 V

  1. Remove the fuel sender gauge assembly.

  1. Connect the fuel sender gauge connector.



    E108388E01

  1. Check that the float position is between E and F.

  1. Measure the resistance between terminals 2 and 1 of connector of the connector.

    Standard resistance:
    Float level
    		Float Position
    		Specified Condition
    F
    		69.9 to 75.9 mm (2.75 to 2.99 in.)
    		6.5 to 8.5 Ω
    E
    		103.1 to 109.1 mm (4.06 to 4.30 in.)
    		167.9 to 171.9 Ω

5.CHECK HARNESS AND CONNECTOR (COMBINATION METER - FUEL SENDER GAUGE (MAIN))


    E108558E05

  1. Disconnect the V9 fuel sender gauge connector.

  1. Disconnect the L31 meter connector.

  1. Measure the resistance of the wire harness side connector.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    L31-19 - V9-2
    		Always
    		Below 1 Ω
    V9-2 - Body ground
    		Always
    		10 kΩ or higher
