FLUID CHECK

M1221011500066

Refer to GROUP 27, On-vehicle service 

P.27-28

.

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.51-15

.)

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 cancelled auto-
matically. Also, using the clear key on the scan tool, the 
activation can be forcibly cancelled.

•

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

• Keep the fluid level above the oil filter while air-bleed-

ing. If you fail to do so, an "air layer" will be present 
below the oil filter. This can cause the fluid not to be 
added below the oil filter.

• If the fluid level should have decreased below the oil fil-

ter, squeeze and release the feed hose so that the fluid 
should be added below the oil filter.

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.27-28

.)

12.Install the engine room under cover front B assembly. (Refer 

to GROUP 51, Under cover 

P.51-15

.)

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.
