Replacement [11/2015 - ]: Procedure

  1. REPLACE BRAKE FLUID (for Using the Techstream) 
    NOTE:
    • Add brake fluid carefully and check that the fluid level remains between the MIN and MAX lines on the brake fluid reservoir.
    • Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.
    1. Disengage the 4 claws and 6 guides, and separate the center No. 1 cowl top ventilator louver.

    2. Replace brake fluid.
      1. Remove the brake master cylinder reservoir filler cap assembly.

      2. Add brake fluid into the reservoir 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 ignition switch to ON (IG).
      4. Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Air Bleeding.
      5. Select "Usual air bleeding" on the Techstream display, 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.

        front bleeder plug 

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

        rear bleeder plug 

        Torque: 8.5 N*m (87 kgf*cm, 75 in.*lbf) 

      7. Install the brake master cylinder reservoir filler cap assembly.
    3. Clear the DTCs (Refer to DTC CHECK / CLEAR [11/2015 - ] ).
    4. Turn the Techstream off and turn the ignition switch off.
    5. Inspect for brake fluid leaks.
    6. Engage the 4 claws and 6 guides to install the center No. 1 cowl top ventilator louver.
  2. REPLACE BRAKE FLUID (for not Using the Techstream) 
    NOTE:
    • Performing the following procedure will enable 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 enabled.
    • 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 cancelled, 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 ignition switch is turned to ON (READY).
      The ignition switch is turned off.
      The parking brake is released.
      The vehicle speed is not 0 km/h (0 mph).
    • Do not rotate the front disc or rear drum while ECB (Electronically Controlled Brake system) Invalid Mode is enabled. If the front disc or rear drum is rotated, ECB (Electronically Controlled Brake system) Invalid Mode may be cancelled.
    • 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 for 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.
    • Do not stand the fluid can on the reservoir inlet. Doing so will cause brake fluid to overflow.
    1. Remove all 4 wheels.
    2. Enable ECB (Electronically Controlled Brake system) Invalid Mode.
      1. Perform the procedure listed below in 1 minute.
        1. Turn the ignition switch to 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 in 5 seconds.
        3. Move the shift lever to P and then depress the brake pedal more than 8 times in 5 seconds.
        4. Move the shift lever to N and then depress the brake pedal more than 8 times in 5 seconds.
        5. Move the shift lever to P.
      2. Check that the brake warning light / yellow is blinking.

      2. Add brake fluid into the reservoir 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 *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.

      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 operating.*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 the brake booster pump assembly operating and depress the brake pedal again.
      11. Tighten the bleeder plug, then release the brake pedal.*4
