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.

 Inspection Procedure 11: The column switch signal is not received.

COMMENTS ON TROUBLE SYMPTOM

The ETACS-ECU receives the column switch signal 
via the LIN communication. If there is an abnormality 
to column switch or LIN bus line, the lights and 
wiper/washer do not work normally.

PROBABLE CAUSES

• Malfunction of column switch

• Faulty LIN bus line

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if diagnosis code is set to the ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Refer to Diagnosis code chart 

P.54A-281

.

NO : 

Go to Step 2.

STEP 2. Column switch check

• Check the continuity for wiper switch. Refer to 

P.54A-206

.

• Check the continuity for column switch (switch 

body part). Refer to 

P.54A-207

.

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 column switch.

Inspection Procedure 12: The stop lamp switch signal is not received.

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
Immobilizer System 

− How to Register Key ID 

P.54A-33

.)

COMMENTS ON TROUBLE SYMPTOM

The stop lamp switch input signal is used for the 
operation judgment of the functions below. If the sig-
nal is abnormal, these functions will not work.

• ABS, ASC

• Shift lock mechanism

• OSS

• Cruise control system

PROBABLE CAUSES

• Malfunction of stop lamp switch
• Malfunction of stop lamp relay

*

• Malfunction of ETACS-ECU

• Damaged harness wires and connectors

NOTE: 

*

: The stop lamp relay cannot be inspected 

because it is a semiconductor relay.

DIAGNOSIS PROCEDURE

connector.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the connector(s) or wiring harness

STEP 4. Check of short to power supply, short to 
earth, and open circuit in STP line between 
ETACS-ECU connector and stop lamp switch 
connector.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the connector(s) or wiring harness

STEP 5. M.U.T.-III data list
Temporarily replace the stop lamp relay, and then 
depress the brake pedal.
