NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-129 <front or side LH>, C-113 
<rear RH> or C-111 <side RH> and junction block 
connector C-210 <front LH, side or rear RH>, C-217 
<rear LH> or C-214 <front RH or 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.

INSPECTION PROCEDURE I-3: Any of the turn-signal lamps does not illuminate. <RH drive vehicles>

CAUTION

Whenever the ECU is replaced, ensure that the 

input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If any of the turn-signal lamp does not illuminate nor-

mally, wiring harness connector(s) or the bulb may 

be defective.

POSSIBLE CAUSES

• Defective turn-signal lamp bulb

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Connector check: A-39 <front RH> or 

A-31 <front LH> headlamp assembly connector, 

A-01 <side RH> or A-02 <side LH> side 

turn-signal lamp connector, F-08 <rear RH> or 

F-14 <rear LH> rear combination lamp connector, 

C-02 <turn-signal indicator lamp> and C-01 

<turn-signal indicator lamp (LH)> 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 turn-signal lamps 
or the turn-signal indicator lamps.
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.
