NOTE: 

Prior to the wiring harness inspection, check junction 
block connector C-210, and repair if necessary.

• Check the output lines for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the wiring harness. Go to Step 23.

STEP 8. Retest the system.
Check that the front turn-signal lamps illuminate nor-
mally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ). Go to Step 23.

NO : 

Replace the front turn-signal lamp. Go to 
Step 23.

STEP 9. Connector check: A-114 side turn-signal 
lamp (LH) connector or A-101 side turn-signal 
lamp (RH) connector.

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Repair the defective connector. Go to Step 
23.

STEP 10. Check the bulb(s) of side turn-signal 
lamps.
Check the bulb(s) of the defective lamp.

Q: Is the check result normal?

YES : 

Go to Step 11.

STEP 11. Resistance measurement at the A-114 
side turn-signal lamp (LH) connector or A-101 
side turn-signal lamp (RH) connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance measurement between the defective 

lamp connector terminal and body earth.

• Resistance between A-114 side turn-signal 

lamp (LH) connector terminal No.1 and body 
earth

• Resistance between A-101 side turn-signal 

lamp (RH) connector terminal No.1 and body 
earth

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 13.

NO : 

Go to Step 12.

STEP 12. Check the wiring harness from A-114 
side turn-signal lamp (LH) connector terminal 
No.1 or A-101 side turn-signal lamp (RH) 
connector terminal No.1 and 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 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Repair the wiring harness. Go to Step 23.
