FUEL LID OPENER SYSTEM > Fuel Lid Opener does not Operate

for Preparation Click here


DESCRIPTION

  1. When the fuel lid opener switch on the integration control and panel assembly is pressed, a fuel lid open request signal is sent to the cowl side junction block LH ECU via the BEAN line. Upon receiving the signal, the ECU actuates the FUEL OPEN relay, which causes the fuel lid with/motor lock assembly (fuel lid opener motor) to open the fuel lid.

INSPECTION PROCEDURE

1.INSPECT FUSE (FUEL OPEN)

  1. Remove the FUEL OPEN fuse from the cowl side junction block LH.

  1. Measure the resistance of the fuse.

    Standard resistance:
    Below 1 Ω



NG
REPLACE FUSE
OK


2.READ VALUE OF DATA LIST (FUEL LID OPENER SWITCH)

  1. Use the Data List to check if the switch is functioning properly.

    Instrument control and panel assembly (fuel lid opener switch): 
    Item
    		Measurement Item/Display (Range)
    		Normal Condition
    		Diagnostic Note
    FUEL Lid Opn SW
    		Fuel lid opener switch signal ON / or OFF
    		ON: Fuel lid opener switch is pressed
    OFF: Fuel lid opener switch is not pressed
    		-

    OK:
    When the switch is operating, the intelligent tester should display as shown in the chart.



NG
REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY (FUEL LID OPENER SWITCH)
OK


3.PERFORM ACTIVE TEST BY INTELLIGENT TESTER (FUEL LID OPENER MOTOR)

  1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the fuel lid opener motor operates normally.

    Cowl side junction block LH ECU: 
    Item
    		Test Details
    		Diagnostic Note
    FUEL Lid Open SW
    		Operate fuel lid opener motor
    ON: Fuel lid is opened
    OFF: Fuel lid is not opened
    		-

    OK:
    Fuel lid is opened.



NG
Go to step 4
OK

REPLACE COWL SIDE JUNCTION BLOCK LH 

4.INSPECT FUEL LID MOTOR LOCK ASSEMBLY
B105769E02

  1. Apply battery voltage to the lock and check operation of the lock.
    OK: 
    Measurement Condition
    		Specified Condition
    Battery positive (+) → Terminal 2
    Battery negative (-) → Terminal 1
    		Shaft moves to open direction

  1. Check the shaft strokes.

    Shaft stroke:
    10.3 mm (0.41 in.) or more



NG
REPLACE FUEL LID MOTOR LOCK ASSEMBLY
OK


5.CHECK WIRE HARNESS (COWL SIDE JUNCTION BLOCK LH - BATTERY)
B105770E03

  1. Disconnect the PM junction block connector.

  1. Measure the voltage.

    Standard voltage:
    Tester Connection
    		Specified Condition
    PM-1 - Body ground
    		10 to 14 V



NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


6.CHECK WIRE HARNESS (FUEL LID MOTOR LOCK ASSEMBLY - COWL SIDE JUNCTION BLOCK LH AND BODY GROUND)
B105771E04

  1. Disconnect the W28 motor connector.

  1. Disconnect the PJ junction block connector.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    W28-2 - PJ-25
    		Below 1 Ω
    W28-1 - Body ground
    		Below 1 Ω



NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK
