Diagnostic method for monitoring a plug-in connection

摘要

A diagnostic method for monitoring at least one plug-in connection ( 4 ) to an antenna ( 1 ), a diagnostic signal is supplied via the antenna signal path toward the antenna ( 1 ). The diagnosis signal bypasses an active circuit ( 31 ) in the antenna signal path. In the event of a defective plug-in connection ( 4 ), the diagnostic signal influences the power supply of the active circuit ( 31 ). If the power consumption is outside a predefined window, an error is signaled.
