INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST BY INTELLIGENT TESTER

  1. Operate the intelligent tester according to the steps on the display and select "ACTIVE TEST".

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

    OK:
    Needle indication is normal.



NG
REPLACE COMBINATION METER ASSEMBLY
OK


2.READ VALUE OF INTELLIGENT TESTER

  1. Operate the intelligent tester according to the steps on the display and select "DATA LIST".

    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 (1/2): 148
    Fuel gauge indicates (E): 205
    		-

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



OK
REPLACE COMBINATION METER ASSEMBLY
NG


3.INSPECT COMBINATION METER ASSEMBLY


    E111204E01

  1. Disconnect the fuel tank wire.

  1. Shorten the terminals 3 (FE) and 4 (FS) on wire harness side.

  1. Disconnect the battery (-) terminal, then reconnect.

  1. Turn the ignition switch to the ON position.

    OK:
    Fuel receiver gauge indicates F or more.



OK
Go to step 6
NG


4.CHECK HARNESS AND CONNECTOR (BETWEEN COMBINATION METER AND FUEL TANK WIRE)


    E111205E02

  1. Disconnect the C9 connector and fuel tank wire.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    C9-2 (FE) -
    C9-19 (FUEL SENDER)
    		Always
    		Below 1 Ω
    C9-19 (FUEL SENDER)
    - Body ground
    		Always
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


5.REPLACE COMBINATION METER ASSEMBLY

NG

REPLACE HYBRID VEHICLE CONTROL ECU 

6.INSPECT FUEL TANK WIRE


    E111231E01

  1. Disconnect the fuel tank wire from the fuel sender gauge assembly.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    2 (FS) - 4 (L2)
    		Always
    		Below 1 Ω
    3 (FE) - 3 (FE)
    		Always
    		Below 1 Ω
    4 (L2) - Body ground
    		Always
    		10 kΩ or higher



NG
REPLACE FUEL TANK WIRE
OK


7.INSPECT FUEL SENDER GAUGE ASSEMBLY


    E110201E04

  1. Check the operation of the float moving smoothly between F and E.

  1. Disconnect the fuel sender gauge connector.

  1. Remove the fuel sender gauge assembly.

  1. Measure the resistance between the terminals 2 (FE) and 3 (FS) of connector according to the value(s) in the table below.

    Standard Resistance:
    Float Level
    		Resistance (Ω)
    F
    		13.5 to 16.5
    E
    		405.5 to 414.5



NG
REPLACE FUEL SENDER GAUGE ASSEMBLY
OK
