FUEL LID OPENER SYSTEM Fuel Lid Opener does not Operate

DESCRIPTION

• When the fuel lid opener switch is pushed, a fuel lid opener switch signal is sent to the main body ECU to the rear junction block ECU via the CAN line. If the main body ECU is not sounding the alarm or is not in the warning state, the main body ECU sends a fuel lid open output request signal to the rear junction block ECU via the CAN line, and operates the fuel lid with motor lock (fuel lid opener motor).

2. INSPECT FUSE (FUEL OPN)

   
   

   1. Remove the FUEL OPN fuse from the luggage room junction block ECU.

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

      Standard resistance
      Tester Connection Condition Specified Condition FUEL OPN fuse Always Below 1 Ω

   
   

   NG

   REPLACE FUSE

   OK

3. PERFORM ACTIVE TEST USING 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 opening lid lock (fuel lid opener motor) operates normally.

      Body No.4:

      Tester Display	Test Part	Control Range
      Fuel Lid Open	Operate fuel lid opening lid lock (fuel lid opener motor)	ON / OFF

      OK
      Fuel lid is opened by "ACTIVE TEST".

   
   

   OK

4. INSPECT FUEL LID OPENING LID LOCK SUB-ASSEMBLY (FUEL LID OPENER MOTOR)

   

   *1	Open
   *2	Shaft Stroke

   
   

   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

   2. Check the shaft strokes.

      Shaft stroke
      10.6 mm (0.406 in.) or more

5. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER MOTOR - REAR JUNCTION BLOCK ECU AND BODY GROUND)

   

   *1	Front view of wire harness connector: (to Fuel Lid Opener Motor)
   *2	Front view of wire harness connector: (to Rear Junction Block ECU)
   *3	FUO

   
   

   1. Disconnect the S42 motor connector.

   2. Disconnect the S61 ECU connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition S42-2 - S61-1 (FUO) Always Below 1 Ω S42-1 - Body ground S61-1 (FUO) - Body ground Always 10 kΩ or higher

   
   

   OK

   REPLACE LUGGAGE ROOM JUNCTION BLOCK ASSEMBLY

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

6. READ VALUE USING DATA LIST (FUEL LID OPENER SWITCH)

   
   

   1. Use the DATA LIST to check if the switch is functioning properly.

      Main Body:

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Fuel Lid Opener Switch	Fuel lid opener switch signal/ON or OFF	ON: Fuel lid opener switch is pushed OFF: Fuel lid opener switch is not pushed	-

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

   
   

   OK

   REPLACE MAIN BODY ECU (DRIVER SIDE JUNCTION BLOCK)

   NG

7. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER SWITCH - MAIN BODY ECU AND BODY GROUND)

   

   *1	Front view of wire harness connector: (to Fuel Lid Opener Switch)
   *2	Front view of wire harness connector: (to Main Body ECU)
   *3	FUSW

   
   

   1. Disconnect the L3 switch connector.

   2. Disconnect the L13 ECU connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition L3-2 (B) - L13-24 (FUSW) Always Below 1 Ω L3-3 (L) - Body ground L13-24 (FUSW) - Body ground Always 10 kΩ or higher

   
   

   OK
