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

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
