Replacement [10/2014 - ]: Procedure

  1. REPLACE BRAKE FLUID (When Using the Techstream) 
    NOTE:
    • Add brake fluid carefully and check that the reservoir level remains between the MIN and MAX lines on the brake fluid reservoir.
    • As brake fluid may overflow when replacing brake fluid, do not place the fluid can on the reservoir filler opening.
    1. Replace the brake fluid.
      1. Remove the brake master cylinder reservoir filler cap assembly.

      2. Add brake fluid to the reservoir until the fluid level is between the MAX and MIN lines on the brake fluid reservoir.

        Brake Fluid

        SAE J1703 or FMVSS No. 116 DOT3

      3. Connect the Techstream to the DLC3 and turn the power switch on (IG).
      4. Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Air Bleeding.
      5. Select "Usual air bleeding", and replace the brake fluid following the instructions on the Techstream.

        HINT: 

        It is not necessary to disconnect the reservoir level switch connector.

      6. After replacing brake fluid, tighten each bleeder plug.

        Torque: 8.3 N*m (85 kgf*cm, 73 in.*lbf) 

    2. Clear the DTCs (Refer to DTC CHECK / CLEAR [10/2014 - ] ).
    3. Turn the Techstream off and turn the power switch off.
    4. Inspect for brake fluid leaks.
    5. Install the brake master cylinder reservoir filler cap.
  2. REPLACE BRAKE FLUID (When not Using the Techstream) 
    NOTE:
    • Performing the following procedure will select ECB (Electronically Controlled Brake system) Invalid Mode without using the Techstream.
    • ECB (Electronically Controlled Brake system) Invalid Mode allows the brake fluid to be replaced without using the Techstream.
    • The brake warning light (yellow) will blink to indicate when ECB (Electronically Controlled Brake system) Invalid Mode is selected.
    • Be sure to inspect that the brake warning light (yellow) is blinking while replacing the brake fluid.
    • When one of the following conditions is met, ECB (Electronically Controlled Brake system) Invalid Mode is canceled, and DTCs may be stored. Do not cancel ECB (Electronically Controlled Brake system) Invalid Mode while replacing brake fluid.
      The shift lever is moved to any other position from P.
      The power switch is turned on (READY).
      The power switch is turned off.
      The parking brake is released.
      The vehicle speed is not 0 km/h (0 mph).
    • Do not rotate the brake disc while ECB (Electronically Controlled Brake system) Invalid Mode is selected.
    • When replacing the brake fluid from the brake line, do not depress the brake pedal to operate the brake booster pump assembly for more than 100 seconds. If the brake booster pump assembly is operated more than 100 seconds, ECB (Electronically Controlled Brake system) Invalid Mode is automatically finished and DTCs may be stored.
    • Add brake fluid carefully and check that the fluid level remains between the MIN and MAX lines on the brake fluid reservoir.
    • As brake fluid may overflow when replacing brake fluid, do not place the fluid can on the reservoir filler opening.
    1. Remove all 4 wheels.
    2. Select ECB (Electronically Controlled Brake system) Invalid Mode.
      1. Perform the procedure listed below within 1 minute.
        1. Turn the power switch on (IG) with the shift lever in P and the parking brake applied.
        2. Move the shift lever to N and then depress the brake pedal more than 8 times within 5 seconds.
        3. Move the shift lever to P and then depress the brake pedal more than 8 times within 5 seconds.
        4. Move the shift lever to N and then depress the brake pedal more than 8 times within 5 seconds.
        5. Move the shift lever to P.
      2. Check that the brake warning light is blinking.

      2. Add brake fluid to the reservoir until the fluid level is between the MAX and MIN lines on the brake fluid reservoir.

        Brake Fluid

        SAE J1703 or FMVSS No. 116 DOT3

      3. Connect a vinyl tube to the bleeder plug of the front disc brake cylinder assembly RH.
      4. Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1
      5. When fluid stops coming out, tighten the bleeder plug, and then release the brake pedal.*2
      6. Repeat steps *1 and *2 until all the air in the brake fluid is completely bled out and new brake fluid comes out.
      7. Tighten the bleeder plug completely.

        Torque: 8.3 N*m (85 kgf*cm, 73 in.*lbf) 

      8. Replace the brake fluid from the front disc brake cylinder assembly LH using the same procedure as for the RH side.
      9. Connect a vinyl tube to the bleeder plug of the rear disc brake cylinder assembly LH.
      10. Loosen the bleeder plug while depressing and holding the brake pedal, and replace the brake fluid with the brake booster pump assembly and solenoid running.*3
        NOTE:
        • Be sure to keep the brake pedal depressed.
        • Do not depress the brake pedal to operate the brake booster pump assembly for more than 100 seconds. When performing this procedure continuously, release the brake pedal to stop brake booster pump assembly operation and depress the brake pedal again.
      11. Tighten the bleeder plug, then release the brake pedal.*4
      12. Repeat steps *3 and *4 until all the air in the brake fluid is completely bled out and new brake fluid comes out.
      13. Tighten the bleeder plug completely.

        Torque: 8.3 N*m (85 kgf*cm, 73 in.*lbf) 

      14. Replace the brake fluid from the rear disc brake cylinder assembly RH using the same procedure as for the LH side.
      15. Turn the power switch off.
    4. Inspect for brake fluid leaks.
