STEP 9. Check the wiring harness between A-13X
front fog lamp relay connector terminal No.2 and
C-219 ETACS-ECU connector terminal No.67.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-33, and repair if necessary.
• Check the output lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the wiring harness.
STEP 10. Retest the system
Check that the front fog lamps illuminate normally.
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 :
Replace the ETACS-ECU and register the
ID codes (Refer to

DIAGNOSIS PROCEDURE
STEP 1. Connector check: A-52 front fog lamp
(LH) connector or A-53 front fog lamp (RH)
connector
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector.
STEP 2. Check the bulbs of the front fog lamps
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. Resistance measurement at the A-52
front fog lamp (LH) connector or A-53 front fog
lamp (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-52 front fog lamp (LH)
connector terminal No.1 and body earth
• Resistance between A-53 front fog 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 5.
NO :
Go to Step 4.
