STEP 10. Check the ground circuit to the rear combination
lamp (LH). Measure the resistance at rear combination
lamp (LH) connector F-09.
(1) Disconnect rear combination lamp (LH) connector F-09 and

measure the resistance available at the wiring harness side
of the connector.

(2) Measure the resistance value between terminal 2 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 12.
NO : Go to Step 11.

STEP 11. Check the wiring harness between rear
combination lamp (LH) connector F-09 (terminal 2) and
ground.
Q: Is the wiring harness between rear combination lamp

(LH) connector F-09 (terminal 2) and ground in good
condition?
YES : Replace the rear combination lamp socket (LH).

Verify that the taillamp (LH) illuminates normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
