1. A hydraulic pressure controller for a vehicle, the controller comprising:
a hydraulic pressure control mechanism including a brake control valve for controlling a hydraulic pressure of a brake fluid; and
a control substrate including a brake control circuit that controls an operation of the brake control valve,
wherein the control substrate includes a suspension control circuit that controls an operation of a suspension control valve for controlling a damping force of a suspension of the vehicle, a first relay that enables energization between the brake control valve and a power supply when the first relay is in a closed state, and that shuts off energization between the brake control valve and the power supply when the first relay is in an open state, and a second relay that is separate from the first relay, that enables energization between the suspension control valve and the power supply when the second relay is in a closed state, and that shuts off energization between the suspension control valve and the power supply when the second relay is in an open state.
