STEP 9. Check fog light (RH) connector A-31 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is fog light (RH) connector A-31 in good condition?
YES : Go to Step 10.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Verify that the fog lights illuminate normally.
STEP 10. Check the ground circuit to the fog light (RH).
Test at fog light (RH) connector A-31.
(1) Disconnect fog light (RH) connector A-31 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 equal 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 fog light (RH)
connector A-31 (terminal 2) and ground.

NOTE: Also check intermediate connector A-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector A-25 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection
Q: Is the wiring harness between fog light (RH) connector
A-31 (terminal 2) and ground in good condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the fog lights illuminate normally.
STEP 12. Check joint connector (2) A-15 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is joint connector (2) A-15 in good condition?
YES : Go to Step 13.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Verify that the fog lights illuminate normally.

STEP 13. Check the wiring harness between joint
connector (2) A-15 (terminal 2) and fog light (RH)
connector A-31 (terminal 1).
NOTE: Also check intermediate connector A-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector A-25 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection
Q: Is the wiring harness between joint connector (2) A-15
(terminal 2) and fog light (RH) connector A-31 (terminal
1) in good condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the fog lights illuminate normally.

STEP 14. Check the fog light indicator light bulb.
(1) Remove the fog light indicator light bulb.
(2) Verify that the fog light indicator light bulb is not damaged or
burned out.
Q: Is the fog light indicator light bulb in good condition?
YES : Go to Step 15.
NO : Replace the fog light indicator light bulb. Verify that
the fog light indicator light illuminates normally.
STEP 15. Check combination meter connector D-03 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is combination meter connector D-03 in good
condition?
YES : Go to Step 16.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Verify that the fog light indicator light
illuminates normally.
STEP 16. Check the ground circuit to the fog light indicator
light. Test at combination meter connector D-03.
(1) Disconnect fog light indicator light connector D-03 and
measure the resistance available at the wiring harness side
of the connector.
(2) Measure the resistance value between terminal 57 and
ground.
• The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 18.
