Step 6. Retest the system.

Check that the front door switch (RH) signal is 
received normally.

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 : 

Replace the ETACS-ECU.

INSPECTION PROCEDURE N-5: The column switch (lighting, turn-signal lamp and headlamp washer 
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 column switch (lighting, 
turn-signal lamp and headlamp washer switch) is 
used to operate the functions below. If the signal is 
abnormal, these functions will not work normally.

•

Lamp reminder function

•

Headlamp and tail lamp

•

Fog lamp

•

Turn signal lamp

•

Headlamp washer

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the column switch connector.

Check that the wiper and washer switch connector, 
the lighting switch connector and the switch body 
connector are in good condition.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Check the column switch (lighting switch

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the column switch.

Step 3. Use the MUT-II/III to confirm a diagnosis 
code.

Check that the ETACS-ECU sets a diagnosis code.

Q: Is the diagnosis code set?

YES : 

Refer to diagnosis code chart
