NOTE: Also check junction block connector D-212, joint con-
nector A-16 and intermediate connector D-28 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If junction block connector D-212, joint connector 
A-16 or 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 front turn-signal light 

(RH) connector A-35 (terminal 1) and ETACS-ECU 
connector D-222 (terminal 14) in good condition?
YES : Replace the socket. 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 14. Check the rear turn-signal light bulb (LH).
(1) Remove the rear turn-signal (LH) light bulb.
(2) Verify that the rear turn-signal light bulb (LH) is not 

damaged or burned out.

Q:  Is the rear turn-signal (LH) light bulb in good condition?

YES : Go to Step 15.
NO :  Replace the rear turn-signal (LH) light bulb. Verify that 

the turn-signal lights illuminate normally.

STEP 15. Check rear combination light (LH) connector 
G-02 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is rear combination light (LH) connector G-02 in good 

condition?
YES : Go to Step 16.
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 16. Check the ground circuit to the rear combination 
light (LH). Test at rear combination light (LH) connector 
G-02. 
(1) Disconnect rear combination light (LH) connector G-02 and 

measure the resistance available at the wiring harness side 
of the connector.

(2) Measure the resistance value between terminal 4 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 17.

STEP 17. Check the wiring harness between rear 
combination light (LH) connector G-02 (terminal 4) and 
ground.
Q: Is the wiring harness between rear combination light 

(LH) connector G-02 (terminal 4) and ground in good 
condition?
YES : Replace the socket assembly. 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 18. Check ETACS-ECU connector D-222 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector D-222 in good condition?

YES : Go to Step 19.
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.
