Abstract:
System and method to diagnose shock absorbers (7) on a vehicle (2) and where at least one of the vehicle's wheel axles are air suspended. A control unit (5) with at least one measuring device (4) connected thereto is provided and in which the measuring device (4) measures a signal that corresponds to the oscillations of the vehicle's wheel suspension. The control unit (5) analyzes the characteristic resonance frequency of the vehicle's wheel suspension.
