STEP 16. Check the wiring harness between rear 
combination light (RH) connector F-03 (terminal 2) and 
ground.

Q: Is the wiring harness between rear combination light 

(RH) connector F-03 (terminal 2) and ground in good 
condition?
YES : Replace the rear combination light socket (RH). Verify 

that the taillight (RH) illuminates normally.

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 taillight (RH) illuminates normally.

STEP 17. Check joint connector C-01 for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.

Q: Is joint connector C-01 in good condition?

YES : Go to Step 18.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

STEP 18. Check the wiring harness between rear 
combination light (RH) connector F-03 (terminal 4) and 
joint connector C-01 (terminal 22).

NOTE: Also check junction block connectors C-214 and C-204 
for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If junction block connector C-214 or 
C-204 is damaged, repair or replace the damaged compo-
nent(s) as described in GROUP 00E, Harness Connector 
Inspection

.

Q: Is the wiring harness between rear combination light 

(RH) connector F-03 (terminal 4) and joint connector 
C-01 (terminal 22) in good condition?
YES : Replace the rear combination light socket (RH). Verify 

that the taillight (RH) 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.

STEP 19. Check front combination light (LH) connector 
A-18 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.

Q: Is front combination light (LH) connector A-18 in good 

condition?
YES : Go to Step 20.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

. Check that the front parking light (LH) 

illuminates normally.

STEP 20. Check the front parking light bulb (LH).
(1) Remove the front parking light bulb (LH).
(2) Verify that the front parking light bulb (LH) is not damaged 

or burned out.

Q: Is the front parking light bulb (LH) in good condition?

YES : Go to Step 21.
NO :  Replace the front parking light bulb (LH). Verify that 

the front parking light (LH) illuminates normally.

STEP 21. Check the ground circuit to the front parking 
light (LH). Measure the resistance at front combination 
light (LH) connector A-18.

(1) Disconnect front combination light (LH) connector A-18 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 23.
NO :  Go to Step 22.
