STEP 17. Check the wiring harness between combination
meter connector D-03 (terminal 57) and ground.
NOTE: Also check joint connector D-30 for loose, corroded, or
damaged terminals, or terminals pushed back in the connector.
If joint connector D-30 is damaged, repair or replace the dam-
aged component(s) as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between combination meter
connector D-03 (terminal 57) 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 light indicator light illuminates normally.

NOTE: Also check intermediate connector D-28 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-28 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection
Q: Is the wiring harness between relay box (fuse No.20)
and combination meter connector D-04 (terminal 42) in
good condition?
YES : Replace the combination meter (printed-circuit
board). Verify that the fog light indicator light
illuminates normally.
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 light indicator light illuminates normally.
STEP 20.Check the ground circuit to the fog light (LH). Test
at fog light (LH) connector A-21.
(1) Disconnect fog light (LH) connector A-21 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 22.
NO : Go to Step 21.

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 22. 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 23.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
