Brake Actuator (W/ Vsc) -- On-Vehicle Inspection



1. CONNECT INTELLIGENT TESTER

  1. Turn the ignition switch off.

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine and idle it.

  1. Turn the intelligent tester on.

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



2. CHECK ACTUATOR MOTOR OPERATION
NOTICE:
Do not keep a motor relay on for more than 5 seconds. When operating it consecutively, wait 20 seconds between each operation.

  1. Turn the motor relay on and check the actuator motor operation noise.

  1. Turn the motor relay off.

  1. Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the initial depth of the pedal is maintained for the entire 15 seconds.

  1. Turn the motor relay on and check that the pedal does not pulsate.

  1. Turn the motor relay off and release the pedal.



3. CHECK RIGHT FRONT WHEEL OPERATION
NOTICE:
  1. Be sure to follow the procedures below when turning on a solenoid.
  2. Do not keep a solenoid on for more than 5 seconds. When operating it consecutively, wait 20 seconds between each operation.
  3. The pedal must not be depressed if only the reduction solenoid SFRR, SFLR, SRRR or SRLR is turned on.

  1. With the pedal depressed as much as possible, perform the following operations:

    1. Turn the SFRH solenoid on simultaneously, and check that the pedal cannot be depressed further.

    2. Turn the SFRR solenoid on simultaneously, and check that the pedal can be depressed further.

    3. Turn the motor relay on. Check that the pedal returns to the "depressed as much as possible" position.

    4. Turn the motor relay off and release the pedal.



4. CHECK OTHER WHEEL OPERATION

  1. Using the same procedures above, check the solenoids of the other wheels.
