Abstract
A method for diagnosing a ground fault of a start/stop unit of a motor vehicle and a start/stop system implementing the method. The method comprises, in a preliminary phase, providing a driver device with a ground that can be switched between two positions and connecting a ground output of a start/stop device to the switchable ground. When the vehicle is in operation, at the time of a start/stop instruction: reading a first value of the signal at the input of the reading circuit, then temporarily switching the switchable ground from a first position connected to a ground of the vehicle to a second position connected to a ground resistor; reading a second value of the signal received by the reading circuit when the ground is switched to the ground resistor, and comparing the two read values in order to diagnose a short-circuit to ground fault of the start/stop unit.
