(2) Measure the resistance between the defective 

lamp connector terminal and body earth.

•

Resistance between A-39 <front RH> headlamp 

assembly connector terminal No.7 and body 
earth

• Resistance between A-31 <front LH> head-

lamp assembly connector terminal No.7 and 
body earth

•

Resistance between A-01 <side RH> side 

turn-signal lamp connector terminal No.1 and 
body earth

• Resistance between A-02 <side LH> side 

turn-signal lamp connector terminal No.1 and 
body earth

•

Resistance between F-08 <rear RH> rear combi-

nation lamp connector terminal No.5 and 
body earth

• Resistance between F-14 <rear LH> rear 

combination lamp connector terminal No.5 
and body earth

•

Resistance between C-02 <turn-signal indicator 

lamp> combination meter terminal No.48 and 
body earth

OK: 2 

Ω or less

Q: Is the check result normal?

Step 4. Check the wiring harness from A-39 
<front RH> or A-31 <front LH> headlamp 
assembly connector terminal No.7, A-01 <side 
RH> or A-02 <side LH> side turn-signal lamp 
connector terminal No.1, F-08 <rear RH> or F-14 
<rear LH> rear combination lamp connector 
terminal No.5, or C-02 <turn-signal indicator 
lamp> combination meter connector terminal 
No.48 to body earth.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 5. Connector check: C-226 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the defective connector.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-129 <front or side LH>, C-127 
<rear LH> or C-111 <side RH> and junction block 
connector C-210 <front, side or rear LH>, C-217 
<rear RH> or C-214 <turn-signal indicator lamp>, 
and repair if necessary.

• Check the output lines for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair the wiring harness.

Step 7. Retest the system.
Check that the turn-signal lamps and the indicator 
lamps illuminate normally.

Q: Is the check result normal?

The lamps illuminate normally at both high and low 
beams. : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

The front turn-signal lamps do not illuminate. : 

Replace the socket.

The side turn-signal lamps do not illuminate. : 

Replace the socket.

The rear turn-signal lamps do not illuminate. : 

Replace the socket assembly.

The turn-signal indicator lamps do not illuminate. : 

Replace the combination meter.
