    Abstract: A guard circuit of a diagnostic output line (K-line) of a control unit (ECU) in the event of a ground (GND) disconnection or of a "below ground" condition, where the diagnostic output line (K-line) comprises a first interface DMOS transistor (MI) with a source connected to ground and a drain coupled to the diagnostic output lines (VOUT) through a second DMOS transistor (MP) with a source connected to the output line (VOUT) and a drain connected to the source of the first DMOS transistor (MI), a comparator (COMP) of the voltage (VOUT) of the diagnostic output line with the potential of the ground node (GND), a two-input logic (AND) gate (A1), with an input connected to the output of the comparator (COMP) and the other input coupled to the gate of said first DMOS transistor (MI), whose output controls a current generator (I) forcing a current, limited by a resistor (R), on the diagnostic output line (VOUT), the gate of the second DMOS transistor (MP) being coupled to the connection node between the generator (I) and the limiting resistor (R), employs a third MOS transistor (M) for switching off the second DMOS transistor (MP), functionally coupled in parallel to the resistor (R) and controlled by a line comprising a second current generator (I 1 ) controlled through an inverter (INV) by the output of the comparator (COMP) and forcing a current through a voltage divider (R 1 , R 2 ) on said diagnostic output line (VOUT). The intermediate node of the voltage divider is coupled to a gate of the third MOS transistor (M), and a third current generator (I 2 ) connected between the gate of the third transistor (M) and ground is controlled by the output of the comparator (COMP) in phase to the first current generator (I) and in phase opposition to the second current generator (I 1 ).
