A traction application executing on a vehicle control module receives a traction speed control input to control a traction wheel of the vehicle. Based on the traction speed control input, the traction application determines a setpoint value of a control attribute related to the traction wheel. A diagnostic supervisor receives a measured value of the control attribute related to the traction wheel, and the setpoint value from the traction application. The diagnostic supervisor comprises an empirically-based model of a traction system of the vehicle. Based on the setpoint value, a vehicle battery voltage, the measured value of the control attribute related to the traction wheel and the model, the diagnostic supervisor calculates a virtual value of the control attribute related to the traction wheel. Based on the virtual value and the measured value of the control attribute, the diagnostic supervisor determines a first operating condition of the traction system of the vehicle.
