A process to check a connection between a battery (2) supplying a low-voltage network (1) of a motor vehicle (12), the voltage of which is less than the voltage of a high-voltage network (6) of the motor vehicle (12), and the low-voltage network (1); wherein a DC voltage converter (5), which is configured for exchanging electrical power between the high-voltage network (6) and the low-voltage network (1), connects the high-voltage network (6) to the low-voltage network (1); wherein a DC voltage converter (5) modulates the output voltage into the low-voltage network at a modulation frequency; wherein the current hereby applied and the voltage hereby applied are measured by the battery (2), and a resistance value is determined and evaluated with respect to at least one connection criterion, according to which a connection fault is determined when at least one connection criterion is not fulfilled.
