DESCRIPTION

Each solenoid adjusts pressure which affects each wheel cylinder according to signals from the skid control ECU and controls the vehicle.
The master cut solenoid is closed and blocks the regulator pressure from the electronically controlled brake system control pressure when the system is normal. The master cut solenoid is open and sends the master cylinder and regulator hydraulic pressure to the non-assisted brake wheel cylinders during the fail-safe due to a system malfunction.

HINT:
If the supply voltage decreases, a drop in current may cause a DTC to be stored.

INSPECTION PROCEDURE

NOTICE:
When replacing the brake booster with master cylinder (skid control ECU or brake actuator), perform initialization and calibration of the linear solenoid valve (Click here).

1.CHECK DTC

  1. Clear the DTCs (Click here).
