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

(LH) connector A-19 (terminal 1) and ETACS-ECU
connector D-222 (terminal 15) 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 8. 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 9.
NO : Replace the front turn-signal (RH) light bulb. Verify

that the turn-signal lights illuminate normally.

STEP 9. Check the ground circuit to the front combination
light (RH). Test at front combination light (RH) connector
A-35.
(1) Disconnect front combination light (RH) connector A-35 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 12.
NO : Go to Step 10.

STEP 10. Check front turn-signal light (RH) connector A-35
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is the front turn-signal (RH) connector A-35 in good

condition?
YES : Go to Step 11.
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 11. Check the wiring harness between front turn-
signal light (RH) connector A-35 (terminal 2) and ground.
Q: Is the wiring harness between front turn-signal light

(RH) connector A-35 (terminal 2) and ground 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 12. Check front turn-signal light (RH) connector A-35
and ETACS-ECU connector D-222 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are front turn-signal light (RH) connector A-35 and

ETACS-ECU connector D-222 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.
