Abstract
The invention concerns a method of verifying the proper working of a transponder mounted on a rotating mobile element of a vehicle, characterized in that it includes the steps of: a) measuring a temperature value by means of a temperature sensor connected to the transponder; b) detecting breach of a overheat threshold; c) a monitoring operation carried out by a reader arranged in the vehicle and provided for communicating with the transponder, consisting in executing a command on one of the temperature sensitive elements of the transponder; d) the reader determining the state of the transponder as a function of the response or absence of any response to the command to be executed: (i) if the response is correct, the transponder is operational; (ii) if the response is incorrect, or in the absence of any response, the transponder is not operational.
