Abstract

The method comprises the steps of monitoring the wheels (R1, R2, R3, R4) of a motor vehicle having an antilock brake system (ABS), for fault states, in particular for incorrect tire pressures, 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. Each wheel (R1, R2, R3, R4) to be monitored is assigned a wheel unit (E1, E2, E3, E4) which monitors the respective wheel (R1, R2, R3, R4) for fault states, and wherein at least the wheel position (FL, FR, RL, RR) of a wheel (R1, R2, R3, R4) at which a fault state has occurred is determined by means of output signals of sensors (S1, S2, S3, S4) of the antilock brake system (ABS).
