Brake Fluid Pressure Sensor/Switch: Description and Operation
The pressure switch monitors the pressure accumulation in the accumulator and is turned off when the pressure becomes lower than a prescribed level.
When the pressure switch is turned off, the switching signal is sent to the control unit. Upon receiving the signal, the control unit activates the pump
motor relay to operate the motor.
