Step 4. Check the wiring harness from C-03 fog
lamp switch connector terminal No.2 <L.H. drive
vehicles> or terminal No.6 <R.H. drive vehicles>
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

P.00-6

).

NO :

Repair the wiring harness.

Step 5. Connector check: C-219 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the defective connector.

Step 6. Check the wiring harness from C-219
ETACS-ECU connector No.54 to C-03 fog lamp
switch connector terminal No.5.

•

Check the input line for open circuit.

Q: Is the check result normal?

Go to Step 7.

NO :

Repair the wiring harness.

Step 7. Retest the system.

Check that the front fog lamp switch signal is
received normally.

INSPECTION PROCEDURE N-16: The rear fog lamp switch signal is not received.

CAUTION

Whenever the ECU is replaced, ensure that the
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
Input signal from the rear fog lamp switch is used to
operate the rear fog lamps. If the signal is abnormal,
the rear fog lamps will not illuminate and extinguish
normally.

POSSIBLE CAUSES

•

Malfunction of the fog lamp switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors
