Abstract
The disclosure relates to a method for operating a capacitive sensor arrangement of a motor vehicle, a control unit being provided, the sensor arrangement having at least one electrode and a connection arrangement which is assigned to the electrode and has a connecting line and, on the latter, a connection on the electrode side and a connection on the control unit side, the electrode being controlled during a measurement routine by the control unit and the resulting distance values being determined on the basis of a measurement capacitance formed by the electrode with respect to a reference potential, the electrical connection state of the electrode being checked with respect to the connection to the control unit during a diagnostic routine by the control unit. It is proposed that the connection state is checked during the diagnostic routine by the control unit.
