Abstract
An exemplary method to detect a wear condition of a suspension system component of a vehicle includes the steps of receiving suspension system component data from a vehicle sensor, calculating an amplitude of the suspension system component data as a function of frequency, monitoring the amplitude of the suspension system component data within a predetermined frequency range, determining whether the amplitude of the suspension system component data is greater than a predetermined threshold, and, if the amplitude is greater than the predetermined threshold, transmitting a diagnostic notification.

A method to detect a wear condition of a suspension system component of a vehicle, the method comprising:
- receiving suspension system component data from a vehicle sensor;
- calculating an amplitude of the suspension system component data as a function of frequency;
- monitoring the amplitude of the suspension system component data within a predetermined frequency range;
- determining whether the amplitude of the suspension system component data is greater than a predetermined threshold;
- and,
- if the amplitude is greater than the predetermined threshold, transmitting a diagnostic notification.
A system to detect a wear condition of a suspension component of a vehicle, comprising:
- at least one vehicle sensor;
- and
- an electronic controller in electronic communication with the at least one vehicle sensor, the electronic controller configured to
- receive suspension system component data from the vehicle sensor;
- calculate an amplitude of the suspension system component data as a function of frequency;
- monitor the amplitude of the suspension system component data within a predetermined frequency range;
- determine whether the amplitude of the suspension system component data is greater than a predetermined threshold;
- and,
- if the amplitude is greater than the predetermined threshold, transmit a diagnostic notification.
