Bleeding Step 1 (IBAU ECU OFF)
NOTE:
- IBAU filled with brake oil should be used for bleeding.
- Disconnect the negative (-) battery terminal to turn off IBAU ECU.
- Set the air bleeding tool (SST: 09580-3D100) and the cap of SST (0K585-E8100) to reservoir tank and make pressure (0.3 - 0.35 MPa (43.5 - 50.7 psi)) to it.
- Initiate air bleeding on all bleed screws in the following sequences until air bubbles no longer appear in the fluid. After air bleeding, close the bleed screws.
(1) IBAU (2 bleed screws) (2) 4 wheels (RR -> RL -> FR -> FL)
- Perform air bleeding while stepping on the brake pedal and opening bleed screws; then, close bleed screws and release the brake pedal. Perform this procedure 10 times.
- Bleed screw sequence: (1) IBAU (2 bleed screws) (2) 4 wheels (RR -> RL -> FR -> FL)
- Repeat it until air bubbles no longer appear in the fluid
- Be cautious that air come in the brake line with opening the bleed screws too much.
