ABSTRACT:
A passive start and entry (PASE) system monitors a signal strength of a LF signal detected by a fob. The fob reports the signal strength back to an electronic control unit using an RF signal. The electronic control unit compares the signal strength to a predetermined threshold. If the signal strength is below the threshold, the electronic control unit determines that the fob may not be receiving the LF transmission due to interference and takes corrective action.
