Abstract
A method for monitoring a subsystem installed in a motor vehicle involves a diagnostic unit checking the subsystem for system errors at least during driving cycles of the motor vehicle, the check being carried out for an occurrence as well as for a correction of a system error. The diagnostic unit carries out a misuse assessment based on a frequency of detection of the occurrence and/or the correction of the system error in order to determine whether the detected occurrence and/or the detected correction of the system error is/are based on misuse. If occurrence of the system error is detected, a restricted operating mode is activated or an activated restricted operating mode is continued in which drivability of the vehicle is restricted after a predefinable number of driving cycles has elapsed or after a predefinable travel distance has passed without the correction of the system error being detected.
