Step 3. Resistance measurement at the A-39 
<front RH> or A-31 <front LH> headlamp 
assembly connector, the A-01 <side RH> or A-02 
<side LH> side turn-signal lamp connector, the 
F-08 <rear RH> or F-14 <rear LH> rear 
combination lamp connector, the C-02 
<turn-signal indicator lamp> combination meter 
connector

(1) Disconnect the connector, and measure at the 

wiring harness side.

(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?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

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.
