STEP 15. 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.
NO :  Go to Step 16.

STEP 16. 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 17.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

STEP 19. Check the wiring harness between relay box 
(fuse No.20) and combination meter connector D-04 
(terminal 42).
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 

P.00E-2

.

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.
