Fuel Lid Opener does not Operate
ENGINE HOOD / DOOR: FUEL LID OPENER SYSTEM: Fuel Lid Opener does not Operate
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 hybrid vehicle control ECU. The hybrid vehicle control ECU sends a fuel lid open output request signal to the fuel lid opening lid lock, and operates the fuel lid opener motor.
When the fuel lid opener not operate, one of the following may be malfunctioning: 1) SFI system, 2) FUEL OPN fuse, 3) fuel lid opener switch, 4) fuel lid opener motor, 5) wire harness or connector, or 6) hybrid vehicle control ECU.
If the fuel tank pressure sensor or fuel vapor containment valve is malfunctioning, the hybrid vehicle control ECU stores the DTC and the fuel lid opener motor will not operate.

INSPECTION PROCEDURE
NOTE: If the hybrid vehicle control ECU is replaced, register the ECU communication ID Engine Immobiliser System.
PROCEDURE
1. CHECK DTC OUTPUT (SFI SYSTEM)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menu items: Powertrain / Engine and ECT / Trouble Codes.
(e) Check the DTC(s) and freeze frame data, and write them down.
(f) Check the details of the DTC(s).
Result:
A -- GO TO SFI SYSTEM (DIAGNOSTIC TROUBLE CODE CHART)
B -- Continue to next step.
2. INSPECT FUSE (FUEL OPN)
(a) Remove the FUEL OPN fuse from the instrument panel junction block.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE FUSE (FUEL OPN)
OK -- Continue to next step.
3. READ VALUE USING TECHSTREAM (FUEL LID OPENER SWITCH)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Data List.
(e) Read the Data List according to the display on the Techstream.
Engine and ECT (Hybrid Vehicle Control ECU):
OK:
On the Techstream screen, the item changes between ON and OFF according to the chart above.
NG -- INSPECT FUEL LID OPENER SWITCH
OK -- Continue to next step.
4. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL LID OPENER MOTOR)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Active Test.
(e) Perform the Active Test according to the display on the Techstream.
Engine and ECT (Hybrid Vehicle Control ECU):
OK:
Fuel lid is opened by Active Test.
NG -- INSPECT FUEL LID OPENER MOTOR ASSEMBLY
OK -- REPLACE HYBRID VEHICLE CONTROL ECU
5. INSPECT FUEL LID OPENER MOTOR ASSEMBLY
(a) Remove the fuel lid opener motor Removal.
(b) Apply battery voltage to the lock control and check the motor operates in the open direction.
Standard:
(c) Check the shaft stroke.
Standard:
10.3 mm (0.406 in.) or more.
NG -- REPLACE FUEL LID OPENER MOTOR ASSEMBLY
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER MOTOR - HYBRID VEHICLE CONTROL ECU)
(a) Disconnect the fuel lid opener motor connector.
(b) Disconnect the hybrid vehicle control ECU connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
7. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER MOTOR - BATTERY)
(a) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE HYBRID VEHICLE CONTROL ECU
8. INSPECT FUEL LID OPENER SWITCH
(a) Remove the fuel lid opener switch Removal.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE FUEL LID OPENER SWITCH
OK -- Continue to next step.
9. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER SWITCH - HYBRID VEHICLE CONTROL ECU)
(a) Disconnect the hybrid vehicle control ECU connector.
(b) Disconnect the fuel lid opener switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
10. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER SWITCH - BODY GROUND)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE HYBRID VEHICLE CONTROL ECU
