BRAKE ACTUATOR ON-VEHICLE INSPECTION

PROCEDURE


  1. CONNECT GTS


    1. Warm up the engine.

    2. Turn the engine switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch to ON.

    5. Turn the GTS on.

    6. Enter the following menus: Chassis / ABS/VSC/TRC / Active Test.

      Tech Tips

      Refer to GTS operator's manual for further details.

  2. INSPECT ACTUATOR MOTOR OPERATION


    1. Enter the following menus: Active Test / Motor Relay.


      Chassis > ABS/VSC/TRC > Active Test
      Tester Display
      Motor Relay

    2. Turn the motor relay on, and check for actuator motor operation sounds.

      Note

      Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, set an interval of more than 20 seconds between operations.

    3. Turn the motor relay off.

    4. Depress the brake pedal and hold it for approximately 15 seconds. Check that the brake pedal cannot be depressed further.

    5. With the motor relay on, check that the pedal does not pulsate.

      Note

      Do not keep a motor relay on continuously for more than 5 seconds. When operating it continuously, set an interval of more than 20 seconds between operations.

    6. Turn the motor relay off and release the brake pedal.

  3. INSPECT RIGHT FRONT WHEEL OPERATION

    Note

    Do not turn on a solenoid in a manner different than described below.


    1. Enter the following menus: Active Test / ABS Solenoid.


      Chassis > ABS/VSC/TRC > Active Test
      Tester Display
      ABS Solenoid

    2. Turn the SFRH and SFRR solenoids on simultaneously, and check that the pedal cannot be depressed.

    3. Turn the SFRH and SFRR solenoids off simultaneously, and check that the pedal can be depressed.

    4. Turn the motor relay on, and check that the pedal returns.

      Note

      Do not keep the motor relay on continuously for more than 5 seconds. When operating it continuously, set an interval of more than 20 seconds between operations.

    5. Turn the motor relay off and release the brake pedal.

  4. INSPECT OTHER WHEEL OPERATION


    1. Using the same procedure, check the solenoids of the other wheels.
