NOTE: Also check junction block connector C-214 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If junction block connector C-214 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 front combination light 

(LH) connector A-18 (terminal 1) and ETACS-ECU 
connector C-219 (terminal 14) in good condition?
YES : Replace the front combination light socket (LH). Verify 

that the turn-signal lights illuminate 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 turn-signal lights illuminate normally.

STEP 8. Check front combination light (RH) connector 
A-34 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.

Q: Is front combination light (RH) connector A-34 in good 

condition?
YES : Go to Step 9.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the turn-signal lights illuminate 

normally.

STEP 9. Check the front turn-signal light bulb (RH).
(1) Remove the front turn-signal (RH) light bulb.
(2) Verify that the front turn-signal light bulb (RH) is not 

damaged or burned out.

Q: Is the front turn-signal (RH) light bulb in good 

condition?
YES : Go to Step 10.
NO :  Replace the front turn-signal (RH) light bulb. Verify 

that the turn-signal lights illuminate normally.

STEP 10. Check the ground circuit to the front 
combination light (RH). Measure the resistance at front 
combination light (RH) connector A-34.

(1) Disconnect front combination light (RH) connector A-34 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 12.
NO :  Go to Step 11.

STEP 11. Check the wiring harness between front 
combination light (RH) connector A-34 (terminal 2) and 
ground.

Q: Is the wiring harness between front combination light 

(RH) connector A-34 (terminal 2) and ground in good 
condition?
YES : Replace the front combination light socket (RH). 

Verify that the turn-signal lights illuminate 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 turn-signal lights illuminate normally.

STEP 12. Check ETACS-ECU connector C-219 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

Q: Is ETACS-ECU connector C-219 in good condition?

YES : Go to Step 13.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the turn-signal lights illuminate 

normally.

STEP 13. Check the wiring harness between front 
combination light (RH) connector A-34 (terminal 1) and 

ETACS-ECU connector C-219 (terminal 9).
