Abstract

A method for monitoring the wheels (R1, R2, R3, R4) of a motor vehicle (10) for fault states, in particular for incorrect tire pressures, comprises the steps of: each wheel (E1, E2, E3, E4) to be monitored is assigned a wheel unit (E1, E2, E3, E4) which transmits data (D1, D2, D3, D4) to a central evaluation device (ECU) of the vehicle (10) at least in response to a trigger signal, the occurrence of a fault state and the wheel position (FL, FR, RL, RR) of the wheel (R1, R2, R3, R4) at which the fault state has occurred being indicated. The detection and the indication of the wheel position (FL, FR, RL, RR) of the wheel (R1, R2, R3, R4) at which the fault state has occurred can be triggered after the fault state has been indicated.
