Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions Section.
    NOTE
    On this vehicle, the control module is referred to as the Brake Actuator.

  2.  
  3. Drain brake fluid.
    NOTE
    Do not let brake fluid sit on painted surfaces, as it will eat through the paint. Wash it off immediately.

  4.  
  5. Disconnect the negative battery cable.
  6.  
  7. Separate the radiator reserve tank hose.
  8.  
  9. Remove the radiator reserve tank assembly.
  10.  
  11. Release the lock lever and disconnect the actuator connector.
  12.  
  13. Using Special Tool: SST: 09023-00101, disconnect the 6 brake lines from the actuator assembly with bracket.

  14.  
  15. Use tags or make a memo to identify the places to reconnect:
    1. 1: To Front Wheel Cylinder RH.
    2.  
    3. 2: To Front Wheel Cylinder LH.
    4.  
    5. 3: To Rear Wheel Cylinder RH.
    6.  
    7. 4: To Rear Wheel Cylinder LH.
    8.  
    9. 5: From 1st Master Cylinder.
    10.  
    11. 6: From 2nd Master Cylinder.
      CAUTION
      Do not damage the brake lines and wire harness.

    12.  

  16.  
  17. Remove the 3 bolts and brake actuator assembly with bracket from the body.

  18.  

To install:

  1. Install the brake actuator with bracket with the 3 bolts and tighten to 14 ft. lbs. (19 Nm).
    CAUTION
    Be careful not to damage the brake tubes and wire harness.

  2.  
  3. Connect the brake actuator connector.
  4.  
  5. Using SST (SST: 09023-00101), connect each brake line to the correct position of the brake actuator and tighten to 11 ft. lbs. (15 Nm).
  6.  
  7. Fill reservoir with brake fluid.
  8.  
  9. Bleed master cylinder.
  10.  
  11. Bleed brake line.
  12.  
  13. Check brake fluid leakage and check fluid level in reservoir.
  14.  
  15. Connect cable to negative battery terminal.
  16.  
  17. For systems with VSC, perform the yaw rate sensor zero point calibration.
    NOTE
    While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it and keep it in a stationary condition. (Do not start the engine.)


    NOTE
    Be sure to do this on a level surface (with an inclination of less than 1 degree).

  18.  
  19. Procedures for test mode: Turn the ignition switch off.
    1. Using SST (SST: 09843-18040) or equivalent, connect and terminals TS and CG of the DLC3.
    2.  
    3. Check that the steering wheel is in the straight- ahead position and move the shift lever to the P position. DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position.
    4.  

  20.  
  21. Obtain the zero point of the yaw rate sensor and acceleration sensor:
    1. Turn the ignition switch ON.
    2.  
    3. Keep the vehicle in the stationary condition on a level surface for 2 seconds or more.
    4.  
    5. Check that the VSC warning light is blinking in TEST MODE.
      NOTE
      If the VSC warning light does not blink, perform zero point calibration again.


      NOTE
      The zero point calibration is performed only once after the system enters the test mode.


      NOTE
      Calibration cannot be performed again until the stored data is cleared once.

    6.  

  22.  
  23. Turn the ignition switch off and disconnect the SST from the DLC3.
  24.  
  25. Check the brake actuator using a hand-held tester, as follows:
    1. Connect a hand-held tester to the DLC3.
    2.  
    3. Start the engine and run at idle.
    4.  
    5. Select the ACTIVE TEST mode on the hand-held tester.
      NOTE
      Please refer to the hand-held tester operator-s manual for more information.

    6.  
    7. Inspect actuator motor operation.
    8.  
    9. With the motor relay on, check the actuator motor operation noise.
    10.  
    11. Turn the motor relay off.
    12.  
    13. Depress the brake pedal and hold it for about 15 seconds. Check that the brake pedal cannot be depressed.
    14.  
    15. With the motor relay on, check that the pedal does not pulsate.
      NOTE
      Do not keep a motor relay on for more than 5 seconds continuously. When operating it continuously, set an interval of more than 20 seconds.

    16.  
    17. Turn the motor relay off and release the brake pedal.
    18.  
    19. Inspect right front wheel operation.
      CAUTION
      Never turn on the solenoids in a manner different to those described below.

    20.  
    21. With the brake pedal depressed, perform the following operations.
    22.  
    23. Turn the SFRH and SFRR solenoids on simultaneously, and check that the pedal cannot be depressed.
      NOTE
      Do not keep a solenoid turned on for more than 5 seconds continuously. When operating it continuously, set an interval of more than 20 seconds.

    24.  
    25. Turn the SFRH and SFRR solenoids off simultaneously, and check that the pedal can be depressed.
    26.  
    27. Turn the motor relay on, and check that the pedal returns.
      NOTE
      Do not keep a motor relay turned on for more than 5 seconds continuously. When operating it continuously, set an interval of more than 20 seconds.

    28.  
    29. Turn the motor relay off and release the brake pedal.
    30.  
    31. INSPECT OTHER WHEEL OPERATION
    32.  
    33. Using the same procedure, check the solenoids of the other wheels.

      Left front wheel: SFLH, SFLR
       
      Right rear wheel: SRRH, SRRR
       
      Left rear wheel: SRLH, SRLR
