STEP 4. Check the ground circuit to the ETACS-ECU.
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 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between front
combination light (LH) connector A-18 (terminal 2) and
ground.
Q: Is the wiring harness between front combination light

(LH) connector A-18 (terminal 2) and ground 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 6. 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 7.
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 7. Check the wiring harness between front
combination light (LH) connector A-18 (terminal 1) and
ETACS-ECU connector C-219 (terminal 14).

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.
