SYMPTOM PROCEDURES

Inspection Procedure 1: The both headlamp automatic levelling systems (right and left) do not work 
normally. 

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

2. If the fuel tank is not filled up, put weight in the 

luggage compartment to make up for the fuel 
shortage so that the weight will become 90% of 
full-state weight or heavier. (0.8 kg per litter)

3. There should be no other load in the vehicle other 

than driver or substituted weight of approximately 
75 kg placed in driver's position.

4. Connect the M.U.T.-III to the diagnosis connector 

(For how to connect the M.U.T.-III, refer to 
GROUP 00 

− Diagnosis function ).

5. Turn the ignition switch to "ON" position. (Do not 

start up the engine.)

6. Select the M.U.T.-III screen menu as follows.

(1) Select "ETACS" displayed on the "System 

selection" screen.

(2) Select "Special function."
(3) Select "HS initial position learning."

7. The ETACS-ECU initialisation is completed.

8. Repeat the procedure if a diagnosis code is set by 

turning the ignition switch from "LOCK (OFF)" to 
"ON" again.

9. Perform the headlamp aiming (Refer to Headlamp 

Aiming

OPERATION CHECK OF HEADLAMP AUTOMATIC LEVELLING

M1540303400117

With this inspection, it is simply checked that the 
headlamp automatic levelling motor incorporated in 
the headlamp assembly moves in accordance with 
the vehicle posture.

INSPECTION PROCEDURE

1. Park the vehicle on a level surface.

2. Turn the ignition switch to "ON" position. (Do not 

start up the engine.)

3. At the front or rear jack up point, raise the front 

wheels or rear wheels off the earth.

4. Turn ON the headlamp switch.

5. When the front wheels are raised, the upward 

headlamp beam is controlled with the control 
value applicable to the present vehicle posture, 
and the headlamp beam moves downward.

6. When the rear wheels are raised, the downward 

headlamp beam is controlled with the control 
value applicable to the present vehicle posture, 
and the headlamp beam moves upward.

HEADLAMP AUTOMATIC LEVELLING MOTOR DRIVE TEST

M1540302100425

With this inspection, the headlamp automatic level-
ling motor incorporated in the headlamp assembly is 
forcibly activated and checking the motor for normal 
operation is possible.

DRIVE TEST PROCEDURE (WHEN THE 
M.U.T.-III IS USED)

1. Connect the M.U.T.-III to the diagnosis connector 

(For how to connect the M.U.T.-III, refer to 
GROUP 00 

− Diagnosis function ).

2. Turn the ignition switch to "ON" position. (Do not 

start up the engine.)

3. Turn ON the headlamp switch.

4. Select the M.U.T.-III screen menu as follows.

(1) Select "ETACS" displayed on the "System 

selection" screen.

(2) Select "Actuator test."
(3) Select "A/L actuator."
(4) The headlamp beam moves downward if 

"20%" is set for the "Value select" and upward 
if "80%" is set for the "Value select".

5. The drive test is completed.

DRIVE TEST PROCEDURE (WHEN THE 
M.U.T.-III IS NOT USED)

1. Turn the hazard warning lamp switch to the ON 

position.

2. Within 10 seconds after turning the ignition switch 

from OFF to the ON position (do not start up the 
engine), turn the headlamp switch from OFF to 
ON 5 times repeatedly. If you fail to do this, turn 
the ignition switch to OFF once and repeat from 
the beginning.

3. Within 30 seconds after you complete the step 

above successfully, turn off the hazard warning 
lamp switch.

4. The headlamp beam moves downward for 

approximately 3 seconds and upward for 3 
seconds. Then the beam returns to the position 
applicable to the present vehicle posture.

5. The drive test is completed.
