A vehicle includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator. A pedal feel simulator is coupled to the master cylinder through a switchable valve. An isolation valve is provided to isolate the braking circuit from the master cylinder and the simulator circuit. A controller is programmed to couple the simulator circuit to a pressure sensor positioned in the braking circuit at a designated diagnostic time during which the brake pedal is depressed to generate a brake pedal input while the vehicle is positively parked. Increased fluid pressure from the brake pedal input is observed with the sensor in the braking circuit. The controller checks whether the pressure-increase to brake pedal input relationship indicates efficacy of the simulator circuit for continued operation of brake-by-wire operation.
