CAUTION / NOTICE / HINT

Note

While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch is turned on. Therefore, when servicing brake system components, do not depress the brake pedal or open/close the doors while the auxiliary battery is connected.

PROCEDURE


  1. PRECAUTION

    Note

    After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

  2. DISCONNECT BRAKE BOOSTER PUMP CONNECTOR


    1. B004SBR

      With the power switch off, disconnect the 2 brake booster pump connectors.

  3. PERFORM ACCUMULATOR PRESSURE ZERO DOWN


    1. B004WAIC01
      *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.

      Tech Tips

      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.
