BRAKE ACTUATOR(for LHD) REMOVAL

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. REMOVE FRONT WHEEL LH

  3. REMOVE ABS MOTOR RELAY


    1. A0021WD

      With the power switch off, remove the 2 ABS motor relays (ABS MOTOR NO. 1 relay and ABS MOTOR NO. 2 relay) in order to disable brake control.

  4. PERFORM ACCUMULATOR ZERO DOWN


    1. A00207RC01
      *a 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.


      Chassis > ABS/VSC/TRC > Utility
      Tester Display
      ECB Utility

      Tech Tips

      Using the GTS to perform accumulator 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.

  5. DRAIN BRAKE FLUID

    Note

    If brake fluid leaks onto any painted surface, immediately wash it off.

  6. REMOVE BATTERY SERVICE HOLE COVER LH
