TROUBLESHOOTING

ELECTRIC POWER STEERING (EPS)

NOTE: 

*

: The service data which begins with A or B 

must be used when the steering has become heavy 
without setting any diagnosis code.

When the EPS-ECU shut off electric power steering system operation.

When the diagnosis system stops the EPS-ECU, the 
M.U.T.-III display data will be unreliable.

ACTUATOR TEST REFERENCE TABLE

M1372007800092

The M.U.T.-III activates the following actuators for 
testing.

NOTE: If the EPS-ECU runs down, actuator testing 
cannot be carried out.

NOTE: Actuator testing is only possible when the 
vehicle is stationary.

ON-VEHICLE SERVICE

STEERING WHEEL PLAY CHECK

M1372001001262

1. With the engine running, position the front wheel 

in the straight ahead direction.

2. Measure the circumferential steering wheel play 

until the front wheels actually start operating while 
turning the steering wheel slightly in the left and 
right directions.

Limit value: 30 mm or less

ON-VEHICLE SERVICE

ELECTRIC POWER STEERING (EPS)

37-38

3. If the steering wheel play exceeds the limit value, 

check the steering shaft joint or steering linkage 
for looseness, and replace or repair the faulty 
components if necessary.

4. If the steering wheel play still exceeds the limit 

value after Step 3 is performed, position the 
steering wheel in the straight ahead position, and 
then apply the force (approximately 5 N) in the 
circumferential direction.

 

At this time, check if the circumferential steering 
wheel play is within the standard value.

Standard value: 16.5 mm or less

5. If the steering wheel play is outside the standard 

value after Step 4 is performed, remove the 
steering gear and linkage, and check and adjust 
the pinion total rotation torque(Refer to 

P.37-48

).

STEERING ANGLE CHECK

M1372001101850

CAUTION

After adjusting the steering angle, always per-
form calibration to make ASC-ECU learn the neu-
tral position of the steering wheel sensor. (Refer 
to GROUP 35C, On-vehicle Service 

− Steering 

Wheel Sensor Calibration .) <Vehicles with ASC>
1. Check that the wheel alignment is normal. (Refer 

to GROUP 33 

− On-vehicle Service, Front Wheel 

Alignment Check and Adjustment (Refer to .)

AC000756AB

2. Place the front wheel onto the turning radius 

gauge, and measure the steering angle.

Standard value:

Inner wheel

38

° 50' ± 1° 30'

(Difference 
between right and 
left wheels must 
be 2

°00’ or less)

Outer wheel (Reference value) 32

° 20'

assembly

3. If the measured value is not within the standard 

value, adjust the tie-rod ends (right and left), and 
repeat Steps 1 and 2.

4. If the measured value is not within the standard 

value after performing Step 3, replace the steering 
gear and linkage assembly. (Refer to 

P.37-48

.)

BALL JOINT DUST COVER CHECK

M1372008600820

1. Using your fingers, press the dust cover to check 

for a crack or damage.

2. If there are any cracks in the dust cover or it is 

damaged, replace the tie-rod end (Refer to 

P.37-48

).

NOTE: If the dust cover has a crack or damage, 
the ball joint could be damaged.

BALL JOINT ROTATION TORQUE CHECK

M1372011600381

CAUTION

• To prevent the ball joint thread from being 

damaged during operation, just loosen the 
tie-rod end mounting nut from the ball joint 
(do not remove it.). To remove the ball joint, 
use the special tools.

1. Use the special tool ball joint remover (MB991897 

or MB992011) to disconnect the tie-rod from the 
knuckle.
