• Pump motor:
The pump motor turns on and applies pressure to each brake when braking is activated in the TCS and stability
control state. When in the pressure reduction mode, it causes the brake fluid in the reservoir to return to the master
cylinder.
• Brake master cylinder pressure sensor:
This sensor detects the brake hydraulic pressure in the primary piping when brake is applied in the normal
condition. Also, it detects the pump motor driving state when brake is applied in the TCS and Stability Control state.
• Inlet solenoid valve:
In the ABS, TCS and Stability Control state, this valve is activated in the pressure keeping and pressure reduction
modes to open the fluid passage, thereby restricting increase of the hydraulic pressure applied to the brake caliper.
• Outlet solenoid valve:
In the ABS, TCS and Stability Control state, this valve is activated in the pressure reduction mode to open the fluid
passage, thereby lowering the hydraulic pressure kept in the brake caliper.
• Cut solenoid valve:
When brake is applied in the TCS and Stability Control state, this valve is activated to close the fluid passage,
thereby causing the hydraulic pressure generated by the pump motor to apply to the brake caliper.
• Low pressure solenoid valve:
When brake is applied in the TCS and Stability Control state, this valve is activated to open the fluid passage from
the master cylinder to the pump motor.
Steering angle sensor
The steering angle sensor is assembled with the contact coil as a unit and mounted to the steering column. Detecting
the angle as the steering wheel is turned, it sends that information to the ESP® control module.
