ENGINE HOOD / DOOR: FUEL LID OPENER SYSTEM: Fuel Lid Courtesy Switch Circuit
- Fuel Lid Courtesy Switch Circuit

DESCRIPTION

The ECM detects the fuel lid courtesy switch operation and transmits this data to the Combination meter. According to the data from the ECM, the Combination meter displays "CLOSE FUEL LID" on the multi-information display if the fuel filler door is open, and does not display "CLOSE FUEL LID" if the fuel filler door is closed. If the fuel filler door is closed, but "CLOSE FUEL LID" is displayed on the multi-information display, the fuel lid courtesy switch circuit has a malfunction.

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (FUEL LID OPENING LID LOCK, FUEL FILLER OPENING LID LOCK)

(a) Operate the Techstream according to the display and select the "Data List" Scan Tool Testing and Procedures.

Engine and ECT:





OK:

Switch condition can be switched by actual operation.

NG -- INSPECT FUEL LID MOTOR LOCK ASSEMBLY

OK -- REPLACE ECM Removal

2. INSPECT FUEL LID MOTOR LOCK ASSEMBLY

(a) Remove the lid lock Removal.





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

Standard resistance:





NG -- REPLACE FUEL LID MOTOR LOCK ASSEMBLY Removal
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (FUEL LID COURTESY SWITCH - ECM AND BODY GROUND)

(a) Disconnect the S68 switch connector.





(b) Disconnect the A13 ECM 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.

4. CHECK HARNESS AND CONNECTOR (ECM - COMBINATION METER)

(a) Disconnect the A14 ECM connector.





(b) Disconnect the L10 meter 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.

5. REPLACE ECM

(a) Temporarily replace the ECM with a new one or normally functioning one Removal.

NEXT -- Continue to next step.

6. CHECK METER / GAUGE SYSTEM (MULTI-INFORMATION DISPLAY)

(a) Check the multi-information display when the fuel filler door is closed.

OK:

"CLOSE FUEL LID" is not displayed at the multi-information display.

NG -- REPLACE COMBINATION METER ASSEMBLY Removal

OK -- END (ECM IS DEFECTIVE)
