7. Select “AIR REL INHIBIT” in “ACTIVE TEST”.
8. Loosen the bleeder valve and bleed air with the brake pedal depressed.

NOTE:

Air bleeding is allowed to start from either right or left.

9. After a complete air bleeding, tighten bleeder valve to the specified torque.
10. Check that the fluid level is the reservoir tank is within the specified range after air bleeding.

AIR RELEASE OF SUCTION DRAIN SYSTEM

CAUTION:

• Monitor the fluid level in the reservoir tank during the air bleeding.

• Perform the air bleed procedure within 30 seconds after the transmission of the signal from CON-

SULT-III. When the air bleed is performed afterward, the re-transmission of the signal from CON-

SULT-III is needed.

NOTE:

Air bleed from the bleeder valve is not necessary since this operation is to return brake fluid (air).
1. Turn ignition switch OFF.
2. Connect CONSULT-III.
3. Turn ignition switch (READY).
4. When performing air bleed, following conditions are required.

- Test mode diag code

5. Select “AIR REL DRAIN” in “ACTIVE TEST”.
6. Step on the brake pedal and return brake fluid to reservoir tank.
7. Ensure that no air (bubble) is contained in the brake fluid circulated from reservoir tank.

AIR RELEASE OF REAR WHEEL SYSTEM

CAUTION:

• Monitor the fluid level in the reservoir tank during the air bleeding.

• Always use new brake fluid for refilling. Never reuse the drained brake fluid.
1. Turn ignition switch OFF.
2. Connect 2 motor relays.
3. Connect CONSULT-III.
4. Turn ignition switch (READY).

NOTE:

If CONSULT-III is freezed, erase the DTC.

5. Confirm accumulator pressure level by using “DATA MONITOR” in CONSULT-III.
a. Select “ACC PRESS SEN” in “DATA MONITOR”.
b. Ensure that this voltage is over 3.42 V.
c.

If voltage is under 3.42 V, then step on the brake pedal several time.

7. Connect a vinyl tube to the bleeder valve of the rear brake.
8. Select “AIR REL INHIBIT” in “ACTIVE TEST”.
9. Loosen the bleeder valve and bleed air with the brake pedal depressed.
10. Ensure that there is no air leakage from the bleeder.
11. After a complete air bleeding, tighten bleeder valve to the specified torque.
12. Check that the fluid level is the reservoir tank is within the specified range after air bleeding.

AIR RELEASE OF POWER SUPPLY SYSTEM

CAUTION:

• Monitor the fluid level in the reservoir tank during the air bleeding.

• Always use new brake fluid for refilling. Never reuse the drained brake fluid.

• Perform the air bleed procedure within 10 seconds after the transmission of the signal from CON-

SULT-III. When the air bleed is performed afterward, the re-transmission of the signal from CON-

SULT-III is needed.

NOTE:

• No need to step on the brake pedal.

• Air bleeding is necessary for the front left brake only.
1. Turn ignition switch OFF.
2. Connect CONSULT-III.
3. Turn ignition switch (READY).
4. Connect a vinyl tube to the bleeder valve of the front left brake.
5. When performing air bleed, following conditions must be met.

• ABS relay No.1 and No.2: ON

• Parking brake: ON

• Shift position: P range

• Vehicle speed: 0 km/h (0 MPH)

• Normal power supply voltage

• Normal communication with HV

• ABS motor relay No.1 and No.2 are set

• No failure of brake system (except following items)

- Motor relay

- Accumulator

- Fluid level switch

- Calibration for each sensors and linear solenoid

- Test mode diag code

6. Select “AIR REL PWR SPLY 2” in “ACTIVE TEST”.
7. Loosen the bleeder valve.
8. Ensure that there is no air leakage from the bleeder.
9. After a complete air bleeding, tighten bleeder valve to the specified torque.

AIR RELEASE OF STROKE SIMULATOR SYSTEM

Air Bleed of Stroke Simulator System 1

CAUTION:

Perform the air bleed procedure within 30 seconds after the transmission of the signal from CONSULT-

III. When the air bleed is performed afterward, the re-transmission of the signal from CONSULT-III is

needed.

NOTE:

• Air bleed from the bleeder is not necessary in this stage.

• This process is performed to send air contained in the stroke simulator to piping. Pedal operation only and

no need of air bleed from the bleeder.
