Each solenoid adjusts pressure which affects each wheel cylinder according to signals from the brake ECU and controls the vehicle.
The master cut solenoid (SMC1/2) is closed and blocks the master cylinder pressure from the Electronically Controlled Brake control pressure when the system is normal. The master cut solenoid is open and sends the master cylinder fluid pressure to the non-assisted brake wheel cylinders during the fail safe due to a system malfunction.

Diagnosis Procedure
CAUTION:
When replacing the brake ECU or brake actuator assembly, perform initialization of linear solenoid valve and calibration.
1.INSPECT BRAKE ACTUATOR ASSEMBLY
1. Disconnect the brake actuator connector.
2. Measure the continuity according to the value(s) in the table below.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace brake actuator assembly.
2.CHECK HARNESS AND CONNECTOR (BRAKE ECU - BRAKE ACTUATOR)
1. Turn the ignition switch OFF.
2. Disconnect the brake ECU connectors.
3. Measure the resistance to the value(s) in the table below.
Part 1:
Part 2:
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace harness or connector.
3.RECONFIRM DTC
1. Reconnect the brake ECU connectors and the brake actuator connector.
2. Clear the DTC.
3. Turn the ignition switch ON (READY).
4. Check if the same DTC is recorded.
Result:
A >> Check for intermittent problems (symptom simulation).
B >> Replace brake ECU.
Special Repair Requirement
1.ZERO ADJUSTMENT FOR EACH SENSOR AND OFFSET LEANING FOR LINEAR SOLENOID VALVE
After erasing brake ECU memories, perform zero adjustment of following sensors and initialization of linear solenoid valve.
^ Steering angle sensor: BRC-9, "PERFORM ZERO POINT OF STEERING ANGLE SENSOR: Description". Testing and Inspection
^ Yaw rate/side/decel G sensor: BRC-8, "PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR: Description". Testing and Inspection
^ Brake stroke sensor: BRC-9, "PERFORM ADJUSTMENT OF STROKE SENSOR: Description". Perform Adjustment of Stroke Sensor
^ Linear solenoid valve: BRC-7, "PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION: Description". Perform Initialization of Linear Solenoid Valve and Calibration
