摘要： A method is provided for selectively providing power to at least one component of a vehicle-based receiver module for determining the presence and validity of a transmitted RF signal. The RF signal is a request signal for activating a respective vehicle accessory function. Power is provided to a receiver for a first period of time. The receiver is operated to receive any RF signal that may be present from a remote transmitting device. A received signal strength indicator (RSSI) associated with operating the receiver is determined. A determination is made whether the RSSI is greater than a first predetermined threshold. The power is terminated to the receiver after the first period of time if the RSSI is not greater than the first predetermined threshold.
