A slave node (46, 48, 50, 52) for use with a Local Interconnect Network (LIN network) (40) receives incoming messages from the LIN network (40) in a manner that reduces operating current, power consumption and/or operating temperature. The slave node (46, 48, 50, 52) generally includes an input circuit (60), an electronic processing device (62), associated components such as an Integrated Glass Fog Sensor (IGFS) unit (64), and a transmitting device (66) all mounted on a single circuit board. The input circuit (60), which can either be separate from or incorporated within the electronic processing device (62), pre-filters an incoming message from a LIN bus (42) such that it only wakes the transmitting device (66) out of its low-current sleep mode when required. Stated differently, the transmitting device (66) is removed from an incoming message path so that it is only active when it is transmitting an outgoing message.
