      3. Select "Brake Line Air Bleeding", and bleed air from 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 air bleeding, tighten each bleeder plug.

  2. BLEED BRAKE LINE (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 lines to be bled 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 line bleeding 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 bleeding the brake lines or DTCs may be stored.
      A shift state other than park (P) is selected.
      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 (yellow) will blink and a buzzer will sound while performing brake line bleeding, this is not a malfunction.
    1. Remove all 4 wheels.

      Refer to PROCEDURE - Step 1 [11/2015 - 12/2018] , or refer to PROCEDURE - Step 1 [12/2018 - ]
