STEP 2. Check headlight assembly connector A-56 
(position light:RH) or A-37 (position light:LH), license plate 
light connector F-07 (RH) or F-03 (LH), rear combination 
light connector D-14 (LH) or D-09 (RH), or rear side marker 
light connector F-10 (RH) or F-16 (LH) for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.
Q: Is headlight assembly connector A-56 (position 

light:RH) or A-37 (position light:LH), license plate light 
connector F-07 (RH) or F-03 (LH), rear combination light 
connector D-14 (LH) or D-09 (RH), or rear side marker 
light connector F-10 (RH) or F-16 (LH) in good 
condition?
YES : Go to Step 3.
NO :  Repair the damaged parts.

STEP 3. Bulb check.
Check the bulb(s) of the light that does not illuminate.
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Replace the bulb(s) of the light that does not 

illuminate.

STEP 4. Resistance measurement at headlight assembly 
connector A-56 (position light:RH) or A-37 (position 
light:LH), license plate light connector F-07 (RH) or F-03 
(LH), rear combination light connector D-14 (LH) or D-09 
(RH), or rear side marker light connector F-10 (RH) or F-16 
(LH).
(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 
connector A-37 (position:LH), A-56 (position:RH) (termi-
nal No. 6) and body ground.

•

Measure the resistance between license plate light con-
nector F-03 (LH), F-07 (RH) (terminal No. 1) and body 
ground.

•

Measure the resistance between rear combination light 
connector D-14 (LH), D-09 (RH) (terminal No. 4) and 
body ground.

•

Measure the resistance between rear side marker light 
connector F-16 (LH), F-10 (RH) (terminal No. 1) and 
body ground.

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 6.
NO :  Go to Step 5.

STEP 5. Check wiring harness between headlight 
assembly connector A-56 (position light:RH) or A-37 
(position light:LH) (terminal No. 6),license plate light 
connector F-07 (RH) or F-03 (LH) (terminal No. 1), rear 
combination light connector D-14 (LH) or D-09 (RH) 
(terminal No. 4), or rear side marker light connector F-10 
(RH) or F-16 (LH) (terminal No. 1) and the body ground.
Check the ground wires for open circuit.
NOTE: Before the wiring harness check, check the intermedi-
ate connectors F-15 and F-18 <rear side marker light>, or and 
repair that if necessary.
Q: Is the wiring harness between headlight assembly 

connector A-56 (position light:RH) or A-37 (position 
light:LH) (terminal No. 6),license plate light connector 
F-07 (RH) or F-03 (LH) (terminal No. 1), rear combination 
light connector D-14 (LH) or D-09 (RH) (terminal No. 4), 
or rear side marker light connector F-10 (RH) or F-16 
(LH) (terminal No. 1) and the body ground in good 
condition?
YES : Go to Step 8.
NO :  Repair the wiring harness.

STEP 6. Check ETACS-ECU connector C-304 <headlight 
assembly> or C-311 <license plate light and rear side 
marker light> for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is ETACS-ECU connector C-304 <headlight assembly> 

or C-311 <license plate light and rear side marker light> 
in good condition?
YES : Go to Step 7.
NO :  Repair the damaged parts.

STEP 7. Check Wiring harness between headlight 
assembly connector A-56 (position light:RH) or A-37 
(position light:LH) (terminal No. 4),license plate light 
connector F-07 (RH) or F-03 (LH) (terminal No. 2), rear 
combination light connector D-14 (LH) or D-09 (RH) 
(terminal No. 2), or rear side marker light connector F-10 
(RH) or F-16 (LH) (terminal No. 2) and ETACS-ECU 
connector C-304 (terminal No. 7, 6) <headlight assembly>, 
C-311 (terminal No. 10, 13) <license plate light and rear 
side marker light>.
Check the output lines for open circuit.
NOTE: Before the wiring harness check, check the intermedi-
ate connectors D-12 <license plate light>, F-15 and F-18 <rear 
side marker light> and repair that if necessary.
Q: Is the wiring harness between headlight assembly 

connector A-56 (position light:RH) or A-37 (position 
light:LH) (terminal No. 4),license plate light connector 
F-07 (RH) or F-03 (LH) (terminal No. 2), rear combination 
light connector D-14 (LH) or D-09 (RH) (terminal No. 2), 
or rear side marker light connector F-10 (RH) or F-16 
(LH) (terminal No. 2) and ETACS-ECU connector C-304 
(terminal No. 7, 6) <headlight assembly>, C-311 
(terminal No. 10, 13) <license plate light and rear side 
marker light> in good condition?
YES : Go to Step 8.
NO :  Repair the wiring harness.

STEP 8. Retest the system.
Check that the position light, front side marker light, rear side 
marker light, or license plate light illuminate normally.
Q: Does the position light, front side marker light, rear side 

marker light, or license plate light work normally?
YES <The light illuminate normally at both high and low 
beams.> : The trouble can be an intermittent malfunction 

(Refer to GROUP 00 

− How to use 

Troubleshooting/inspection Service Points 

− How to 

Cope with Intermittent Malfunction

).

NO <When the position light does not illuminate> : 

Replace the position light socket.

NO <When the front side marker lights do not 
illuminate> : Replace the front side marker light socket.
NO <When the license plate light does not illuminate> : 

Replace the license plate light socket.

NO <When the rear side marker lights do not illuminate> 
: 

Replace the rear side maker light socket.
