STEP 2. Check headlight assembly (LH) connector A-40,
rear combination light (LH) connector F-25, taillight (LH)
connector F-24, license plate light connector F-18 (LH) and
F-15 (RH) for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Is headlight assembly (LH) connector A-40, rear
combination light (LH) connector F-25, taillight (LH)
connector F-24, license plate light connector F-18 (LH)
and F-15 (RH) in good condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
STEP 3. Resistance measurement at headlight assembly
(LH) connector A-40, rear combination light (LH) connector
F-25, taillight (LH) connector F-24, license plate light
connector F-18 (LH) and F-15 (RH).
(1) Disconnect the connector, and measure at the wiring
harness side.
(2) Measure the resistance between the connector of light
which does not illuminate and the body ground.
•
Measure the resistance between headlight assembly
(LH) connector A-40 (terminal 6) and the body ground.
•
Measure the resistance between rear combination light
(LH) connector F-25 (terminal 1) and the body ground.

•
Measure the resistance between taillight (LH) connector
F-24 (terminal 1) and the body ground.
•
Measure the resistance between license plate light (LH)
connector F-18 (terminal 1) and the body ground.
•
Measure the resistance between license plate light (RH)
connector F-15 (terminal 1) and the body ground.
OK: The measured value should be continuity
exists (2
Ω or less).
Q: Does the measured resistance value correspond with
this range?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check the wiring harness between headlight
assembly connector, rear combination light connector, tail
light connector or license plate light and the body ground.
Check the ground line for open circuit.
• Check the wiring harness between headlight assembly (LH)
connector A-40 (terminal 6) and the body ground.
• Check the wiring harness between rear combination light
(LH) connector F-25 (terminal 1) and the body ground.
• Check the wiring harness between taillight (LH) connector
F-24 (terminal 1) and the body ground.
NOTE: Also check intermediate connector F-27 for loose,
corroded, or damaged terminals, or terminals pushed back
in the connector. If intermediate connector F-27 is dam-
aged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
.
• Check the wiring harness between license plate light (LH)
connector F-18 (terminal 1) and the body ground.
• Check the wiring harness between license plate light (RH)
connector F-15 (terminal 1) and the body ground.
Q: Is the wiring harness between headlight assembly
connector, rear combination light connector, tail light
connector or license plate light and the body ground in
good condition?
YES : Go to Step 7.
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.
STEP 5. Check ETACS-ECU connectors C-304 <position
light> and C-311 <taillight or license plate light> for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connectors C-304 <position light> and
C-311 <taillight or license plate light> in good
condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection

STEP 6. Check wiring harness between headlight
assembly connector, rear combination light connector,
taillight connector or license plate light and ETACS-ECU
connector.
Check the power supply line for open circuit or short circuit.
• Check the wiring harness between headlight assembly (LH)
connector A-40 (terminal 4) and ETACS-ECU connector
C-304 (terminal 3).
• Check the wiring harness between rear combination light
(LH) connector F-25 (terminal 3) and ETACS-ECU connec-
tor C-311 (terminal 10).
NOTE: Also check intermediate connectors D-17 for loose,
corroded, or damaged terminals, or terminals pushed back
in the connector. If intermediate connector D-17 is dam-
aged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
.
• Check the wiring harness between taillight (LH) connector
F-24 (terminal 2) and ETACS-ECU connector C-311 (termi-
nal 10).
NOTE: Also check intermediate connectors D-17 and F-27
for loose, corroded, or damaged terminals, or terminals
pushed back in the connector. If intermediate connector
D-17 or F-27 is damaged, repair or replace the connector
as described in GROUP 00E, Harness Connector Inspec-
tion
• Check the wiring harness between license plate light (LH)
connector F-18 (terminal 2) and ETACS-ECU connector
C-311 (terminal 10).
NOTE: Also check intermediate connectors D-17 for loose,
corroded, or damaged terminals, or terminals pushed back
in the connector. If intermediate connector D-17 is dam-
aged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
.
• Check the wiring harness between license plate light (RH)
connector F-15 (terminal 2) and ETACS-ECU connector
C-311 (terminal 10).
NOTE: Also check intermediate connectors D-17 for loose,
corroded, or damaged terminals, or terminals pushed back
in the connector. If intermediate connector D-17 is dam-
aged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
.
Q: Is the wiring harness between headlight assembly
connector, rear combination light connector, taillight
connector or license plate light and ETACS-ECU
connector in good condition?
YES : Go to Step 7.
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.
