Abstract
The invention relates to a device for remotely giving warning as to the state of wear of at least one blade of a windshield-wiper system of a vehicle comprising means for determining the wear of said blade and means for flagging said wear; said device is noteworthy in that it comprises at least one unit comprising a module called the removable diagnostic connector able to interact with a diagnostic service connector forming an on-board diagnostic input of the vehicle in order to establish a link with said diagnostic connector via the OBD protocol and means for communicating electronically that are coupled to the diagnostic connector and that are able to transmit, to a portable electronic apparatus, via a wireless link, a message indicating the wear of said blade when the means for determining the wear of the blade generate a signal referred to as a wear signal.
