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?

YES : 

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.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

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

Step 1. Connector check: C-03 fog lamp switch 
connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Check the rear fog lamp switch.

Refer to GROUP 54A 

−

 Rear fog lamp 

P.54A-85

.

Q: Is the check result normal?

YES : 

Go to Step 3.

Step 3. Measure the resistance at the C-03 fog 
lamp switch connector.

(1) Remove the fog lamp switch, and measure at the 

wiring harness side.

(2) Continuity between C-03 fog lamp switch 

connector terminal No.2 and body earth

OK: 2

Ω

 or less
