STEP 7. Check the wiring harness between joint connector
(2) A-15 (terminal 3) and fog light (LH) connector A-21
(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

P.00E-2

.

Q: Is the wiring harness between joint connector (2) A-15

(terminal 3) and fog light (LH) connector A-21 (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 8. Check the fog light bulb (RH).
(1) Remove the fog light bulb (RH).
(2) Verify that the fog light bulb (RH) is not damaged or burned

out.

Q: Is the fog light bulb (RH) in good condition?

YES : Go to Step 9.
NO : Replace the fog light bulb (RH). Verify that the fog

lights illuminate normally.

STEP 9. 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 10.

STEP 10. 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 11.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the fog lights illuminate normally.

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 and fog light (RH)
connector A-31 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are joint connector (2) A-15 and fog light (RH)

connector A-31 in good condition?
YES : Go to Step 13.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
