    PERFORM ACCUMULATOR PRESSURE ZERO DOWN


    1. B004WUTC01
      *a MAX Line
      *b MIN Line

      Drain the brake fluid in the brake master cylinder reservoir assembly to near the MIN line.

    2. Connect the GTS to the DLC3 with the power switch off.

    3. Check that the parking brake is applied, and turn the power switch on (IG).

    4. Turn the GTS on and enter the following menus: Chassis / ABS/VSC/TRC / Utility / ECB (Electronically Controlled Brake System) Utility / Zero Down.


      1. Chassis > ABS/VSC/TRAC > Utility
        Tester Display
        ECB Utility




      Tip:

      Using the GTS to perform accumulator pressure zero down causes the pressurized brake fluid in the accumulator to be returned to the brake master cylinder reservoir assembly.

    5. When the buzzer sounds, turn the power switch off.

    6. Turn the GTS off and disconnect the GTS from the DLC3.
