DIAGNOSTIC PROCEDURE

Step 1. Connector check: A-30 <headlamp RH>, 
A-15 <headlamp LH> headlamp assembly 
connector or C-05 <high-beam indicator> 
combination meter connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Check the bulb(s) of the headlamps or the 
high-beam indicator lamp.

Check the bulb(s) of the defective lamp.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the bulb(s) of the defective lamp.

Step 3. Measure the resistance at A-30 
<headlamp RH>, A-15 <headlamp LH> headlamp 
assembly connector or C-05 <high-beam 
indicator> combination meter connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Check the resistance between the lamp 

connector and body earth.

•

Resistance between A-30 <right headlamp> 

headlamp assembly connector terminal No.2 
and body earth

•

Resistance between A-15 <left headlamp> 
headlamp assembly connector terminal No.2 
and body earth

•

Resistance between C-05 <high-beam indicator 

lamp> combination meter connector terminal 
No.8 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-30 
<right headlamp> or A-15 <left headlamp> 
headlamp connector terminal No.2, or C-05 
<high-beam indicator lamp> combination meter 
connector terminal No.8 to body earth.
