      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

        SAE J1704 or FMVSS No. 116 DOT4

    2. Replace the brake fluid.
      1. Connect the Techstream to the DLC3 and turn the power switch on (IG).
      2. Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Air Bleeding/AHB-R Utility.

        Chassis > ABS/VSC/TRAC > Utility 

        Tester Display
        Air Bleeding/AHB-R Utility
      3. Select "Brake Line Air Bleeding", and replace the brake fluid following the instructions on the Techstream.

        HINT: 

        When the brake pedal is released, the piston inside the master cylinder may take longer than the brake pedal to return to its original position. Therefore, make sure to wait for 1 second or more between each depression of the brake pedal.

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

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

    3. Install the brake master cylinder reservoir filler cap assembly.
    4. Clear the DTCs.

      Refer to DTC CHECK / CLEAR [06/2018 - ]

    5. Turn the Techstream off then turn the power switch off.
    6. Inspect for brake fluid leaks.
  2. REPLACE BRAKE FLUID (when Not Using the Techstream) 
    NOTE:
    • Performing the following procedure enters 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 blinks (yellow) to indicate that ECB (Electronically Controlled Brake system) Invalid Mode is selected.
    • Be sure to confirm that the brake warning light is blinking (yellow) throughout the brake fluid replacement procedure.
    • If any of the following conditions are met, ECB (Electronically Controlled Brake system) Invalid Mode is canceled and the brake warning light (yellow) turns off. Do not allow ECB (Electronically Controlled Brake system) Invalid Mode to be canceled while replacing brake fluid or DTCs may be stored.
      The shift lever is moved from P to any other position.
      The power switch is turned on (READY).
      The power switch is turned off.
      The parking brake is released.
      The vehicle speed is more than 0 km/h (0 mph).
    • Do not rotate any brake disc while ECB (Electronically Controlled Brake system) Invalid Mode is selected.
    • Although the brake warning light will blink (yellow) and a buzzer will sound while performing fluid replacement, this is not a malfunction.
    1. Remove all 4 wheels.

      See step  1

    2. Enter 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 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 (yellow).

      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

        SAE J1704 or FMVSS No. 116 DOT4

    4. Replace the brake fluid.

      HINT: 

      When replacing the brake fluid using vacuum, the brake fluid bottle can be inverted and placed on the reservoir filler opening.

      1. Connect a vinyl tube to the bleeder plug of the front disc brake cylinder assembly RH.
      2. Depress the brake pedal several times with approximately 1 second between each depression, and then loosen the bleeder plug with the pedal depressed.*1
      3. When brake fluid stops coming out, tighten the bleeder plug and then release the brake pedal for 1 second or more.*2

        HINT: 

        When the brake pedal is released, the piston inside the master cylinder may take longer than the brake pedal to return to its original position. Therefore, make sure to wait for 1 second or more between each depression of the brake pedal.

      4. Repeat steps *1 and *2 until new brake fluid comes out.
      5. Tighten the bleeder plug completely.

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

      6. Replace brake fluid from the front disc brake cylinder assembly LH using the same procedure as for the RH side.
      7. Connect a vinyl tube to the bleeder plug of the rear disc brake cylinder assembly LH.
      8. Depress the brake pedal several times with approximately 1 second between each depression, and then loosen the bleeder plug with the pedal depressed.*3
      9. When brake fluid stops coming out, tighten the bleeder plug and then release the brake pedal for 1 second or more.*4

        HINT: 

        When the brake pedal is released, the piston inside the master cylinder may take longer than the brake pedal to return to its original position. Therefore, make sure to wait for 1 second or more between each depression of the brake pedal.

      10. Repeat steps *3 and *4 until new brake fluid comes out.
      11. Tighten the bleeder plug completely.

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

      12. Replace brake fluid from the rear disc brake cylinder assembly RH using the same procedure as for the LH side.
      13. Turn the power switch off.
    5. Inspect for brake fluid leaks.
    6. Adjust the brake fluid level in the reservoir.

      Refer to PROCEDURE - Step 2
