A method of checking the operating characteristics of an electronic unit (1) fitted on a wheel (2) of a vehicle (3) and adapted to transmit, to a central processing unit (7), data frames representative of operating parameters of the wheel according to a procedure for transmitting streams (A) of frames (a) consisting in ordering n successive transmissions of each data frame. This checking method consists in analyzing, on the transmission of each stream of data frames, the number m of data frames actually acquired by the central processing unit (7), so as to deduce from the successive analyses a reception ratio Tr representative of the ratios Σm/Σn, and in ordering the transmission, by the central processing unit (7), of a preventive indication when the reception ratio Tr becomes less than a predetermined reception threshold.
