Step 7. Connector check: F-13-6 side turn-signal 
lamp (RH) or F-07-6 side turn-signal lamp (LH) 
connector.

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the defective connector.

Step 8. Resistance measurement at the F-13-6 
side turn-signal lamp (RH) or F-07-6 side 
turn-signal lamp (LH) connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance measurement between the defective 

lamp connector terminal and body earth.

•

Resistance between F-13-6 side turn-signal lamp 

(RH) connector terminal No.2 and body earth

• Resistance between F-07-6 side turn-signal 

lamp (LH) connector terminal No.2 and body 
earth

OK: 2 

Ω or less

Q: Is the check result normal?

YES : 

Go to Step 19.

NO : 

Go to Step 9.
