INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (FUEL OPN)
(a) Remove the FUEL OPN fuse from the instrument pane J/B (body ECU).
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE (FUEL OPN)
OK -- Continue to next step.
2. PERFORM ACTIVE TEST BY TECHSTREAM
(a) Connect Techstream to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Perform the Active Test according to the tester display.






OK:
Fuel lid opens.
NG -- INSPECT FUEL LID OPENER MOTOR ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
3. INSPECT FUEL LID OPENER MOTOR ASSEMBLY





(a) Remove the fuel lid opener motor assembly Removal.
(b) Apply battery voltage to the lock terminals and check that the motor operates and the shaft moves in the open direction.
OK:





(c) Measure the shaft stroke.
Standard:
10.3 mm (0.406 in.) or more
If the result is not as specified, replace the motor assembly.
NG -- REPLACE FUEL LID OPENER MOTOR ASSEMBLY
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (FUEL LID OPENER MOTOR - HYBRID VEHICLE CONTROL ECU)





(a) Disconnect the H30 ECU connector.
(b) 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.
5. 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 -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
