STEP 6. Check the wiring harness from A-117
position lamp (LH) connector terminal No.1 or A-
37 position lamp (RH) connector terminal No.1, F-
05 <vehicles with rear body> or F-22 <vehicles
without rear body> licence plate lamp (LH)
connector terminal No.2 or F-06 <vehicles with
rear body> or F-21 <vehicles without rear body>
licence plate lamp (RH) connector terminal No.2
to C-218 ETACS-ECU connector terminal No.15.

NOTE:

Prior to the wiring harness inspection, check junction
block connectors C-210 <position lamp>, C-221
<licence plate lamp-LHD>, C-204 <licence plate
lamp-RHD> and intermediate connectors F-07
<licence plate lamp>, C-31 <licence plate lamp-
RHD>, 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.

The lamps 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 ).

When the position lamps do not illuminate :

Replace the position lamp socket.

When the licence plate lamps do not illuminate :

Replace the licence plate lamp socket.

Inspection Procedure 5: One of the headlamps does not illuminate. <2-bulb type>

COMMENTS ON TROUBLE SYMPTOM
When one of the headlamps does not illuminate, the
wiring harness connector(s), the bulb or the fuse may
be defective or burned out.

DIAGNOSIS PROCEDURE

STEP 1. Connector check: A-116 headlamp (LH)
connector or A-126 headlamp (RH) connector

Q: Is the check result normal?

YES <Either of LH side and RH side does not
illuminate> :

Go to Step 2.

YES <Low-beam of LH side or RH side does not
illuminate> :

Go to Step 5.

YES <High-beam of LH side or RH side does not
illuminate> :

Go to Step 9.

NO <The connectors are not in good condition> :

Repair the defective connector.

STEP 2. Resistance measurement at the A-116
headlamp (LH) connector or the A-126 headlamp
(RH) 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-116 headlamp (LH)

connector terminal No.2 and body earth

• Resistance between A-126 headlamp (RH)

connector terminal No.2 and body earth

OK: Continuity exists (2

Ω or less)

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Go to Step 3.
