A multi-mode transmission for a powertrain system includes a high-voltage electrical system with a high-voltage battery and high-voltage electrical bus coupled to a power inverter electrically coupled to torque machines configured to transform electric power to torque. In an embodiment, a device receives pressure data from at least one pressure sensor, where the pressure sensor is associated with furniture used for an individual to sleep. Based on the outcome of the comparing step, decisions are made as to how to update the data records of the first and second databases. Thereafter, the weight of the processed fluid reservoir may be checked to confirm that sufficient fluid has been pumped back into the reservoir to remove the air.
