FLUID CHECK

M1221011500066

Refer to GROUP 27, On-vehicle service 

P.27-29

.

BLEEDING

M1221011600052

CAUTION

At low temperature the fluid viscosity is so high that air 
bleeding becomes degenerated. Air bleeding should be 
done at normal temperatures {10 to 30

° C (50 to 86° F)}. 

1. Raise the vehicle.
2. Remove the engine room under cover front B assembly. 

(Refer to GROUP 51, Under cover 

P.51-16

.)

Bleeder screw

3. Remove the bleeder screw cap of the transfer, then connect 

the vinyl hose.

CAUTION

Before connecting or disconnecting scan tool, always turn 
the ignition switch to the LOCK (OFF) position.
4. Connect scan tool to the data link connector.(Refer to 

P.22A-9

.)

5. Position the steering wheel in a straight ahead direction.
6. Turn the ignition switch to the "ON" position.
7. Perform the actuator test (item No. 01) of scan tool to 

forcibly activate the hydraulic unit.
NOTE: 

.

The forced activation (item No. 01: Air bleeding mode) is 
continued for 5 minutes, then it will be canceled automat-
ically. Also, using the clear key on the scan tool, the acti-
vation can be forcibly canceled.

When the hydraulic unit functions are stopped due to the 
fail-safe, the forced activation cannot be performed.

8. From the straight-ahead position, gradually rotate the 

steering wheel to the right or left. Loosen the bleeder screw, 
and check that the air is bled with fluid.

CAUTION

• During the air bleeding, fill the fluid so that the fluid 

constantly remains in the oil reservoir.

• When the oil is filled into the empty oil reservoir, check 

that the oil is filled up under the filter inside the oil res-
ervoir.

9. After bleeding the air, tighten the bleeder screw.
10.Repeat Steps 7 and 8 for two to three times. After checking 

that air mixing is eliminated, tighten the bleeder screw to the 
specified torque.

Tightening torque: 5.0 

± 1.0 N⋅ m (44 ± 9 in-lb)

CAUTION

If the air bleeding is insufficient, the noise from the 
hydraulic unit occurs, which may deteriorate the pump 
durability.
11.After the air bleeding is complete, check the fluid 

level.(Refer to GROUP 27, On-vehicle service 

P.27-29

.)

ACD OPERATION CHECK

M1221011700060

CAUTION

Before connecting or disconnecting scan tool, always turn 
the ignition switch to the LOCK (OFF) position.
1. Connect scan tool to the data link connector.(Refer to 

P.22A-9

.)

2. Start the engine.
3. Position the steering wheel in a straight ahead direction.
4. Perform the actuator test (item No. 05) of scan tool to 

forcibly activate ACD.
NOTE: 

.

The forced activation (item No. 05: ACD operation check 
mode) is continued for 1 minute, then it will be canceled 
automatically. Also, using the clear key on the scan tool, 
the activation can be forcibly canceled.

When the ACD functions are stopped due to the 
fail-safe, the forced activation cannot be performed.

5. Rotate the steering wheel 180

°  or more to the right or left, 

and drive the vehicle at 20 km/h or less to check that the 
tight corner braking phenomenon occurs.
NOTE: 

.

The occurrence levels of body vibration and noise 
caused by the tight corner braking phenomenon will dif-
fer depending on the conditions of tire and road surface.

If the tight corner braking phenomenon does not occur, 
the system may have an abnormality. Therefore, check 
the hydraulic pressure.

HYDRAULIC PRESSURE CHECK

M1221011800089

1. Remove the rear wheel (RH), then remove the rear wheel 

splash shield.(Refer to GROUP 42A, Splash shield 

P.42A-13

.)

2. Raise the vehicle.

AC707692AC

3. Disconnect the hydraulic unit from the ACD pressure tube 

assembly. Then, connect the special tool below to the 
hydraulic unit side.

• Hose adapter (MB991705)

• Oil pressure gauge (MD998330)

CAUTION

Before connecting or disconnecting scan tool, always turn 
the ignition switch to the LOCK (OFF) position.
4. Connect scan tool to the data link connector.(Refer to 

P.22A-9

.)

5. Turn the ignition switch to the "ON" position.
6. Perform the actuator test (item No. 05) of scan tool to 

forcibly activate ACD.

NOTE: 

.

The forced activation (item No. 05: ACD operation check 
mode) is continued for 1 minute, then it will be canceled 
automatically. Also, using the clear key on the scan tool, 
the activation can be forcibly canceled.

When the ACD functions are stopped due to the 
fail-safe, the forced activation cannot be performed.

CAUTION

During the hydraulic pressure check, fill the fluid so that 
the fluid constantly remains in the oil reservoir.
7. Check that the generated hydraulic pressure of the hydraulic 

unit is within the standard value.

Standard valve: 0.9 

 1.1 MPa (130  159 psi)

8. If the measured value exceeds the standard value, replace 

the hydraulic unit.

9. After applying oil to the flare nut thread of ACD pressure 

tube assembly, connect the assembly to the hydraulic unit, 
then tighten to the specified torque.

Tightening torque: 26 

± 4 N⋅ m (19 ± 3 ft-lb)

10.Perform the air bleeding. (Refer to 

P.22A-118
