Step 7. Retest the system.

Check that the turn-signal lamps and the indicator 
lamps illuminate normally.

Q: Is the check result normal?

The lamps illuminate normally at both high and low 
beams. : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

The front turn-signal lamps do not illuminate. : 

Replace the socket.

The side turn-signal lamps do not illuminate. : 

Replace the socket.

The rear turn-signal lamps do not illuminate. : 

Replace the socket assembly.

The turn-signal indicator lamps do not illuminate. : 

Replace the combination meter.

FOG LAMP

INSPECTION PROCEDURE L-1: The front fog lamps do not illuminate normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

OPERATION
The ETACS-ECU operates this function in 
accordance with the input signals below.

•

Tail lamp switch

•

Headlamp switch

•

Front fog lamp switch

If the front fog lamps do not illuminate normally, 
these input signal circuit(s) or the ETACS-ECU may 
be defective.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Malfunction of the front fog lamp switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check that the tail lamps and headlamps 
operate.

Check that the tail lamps and headlamps illuminate 
normally.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Check the tail lamps and the headlamps 
(Refer to trouble symptom chart 

P.54B-41

).

Step 2. Pulse check

Check the input signals below, which are related to 
the front fog lamps.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

3.

The ignition switch (IG1) signal is not received. : 

Refer to inspection procedure N-2 "The 
ignition switch (IG1) signal is not received 

P.54B-301

."

The tail lamp switch signal is not received. : 

Refer 

to inspection procedure N-5 "The column 
switch (lighting and turn-signal lamp switch) 
signal is not received 

P.54B-319

."

The headlamp switch signal is not received. : 

Refer to inspection procedure N-5 "The 
column switch (lighting and turn-signal lamp 
switch) signal is not received 

P.54B-319

."

The front fog lamp switch signal is not received. : 

Refer to inspection procedure N-15 "The 
front fog lamp switch signal is not received 

P.54B-367

."

Step 3. Connector check: A-05X front fog lamp 
relay connector.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the defective connector.

Step 4. Check the front fog lamp relay.

Refer to GROUP 54A 

−

 Front fog lamp 

P.54A-82

.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the front fog lamp relay.

Step 5. Measure the voltage at the A-05X front fog 
lamp relay connector.

(1) Remove the front fog lamp relay, and measure at 

the relay box side.

(2) Check the voltage between the front fog lamp
