Abstract: A system for testing a suspension system of a vehicle includes an inertial measurement module and a suspension fault detection module. The inertial measurement module is configured to, while the vehicle is not moving, collect sensor data from one or more inertial measurement sensors for different states of the suspension system. The sensor data is indicative of inertial states of the vehicle while the suspension system is in each of the different states. The suspension fault detection module is configured to, based on the sensor data and a set of thresholds, determine whether a fault exists with the suspension system, isolate and identify the fault, and perform a countermeasure based on the detection of the fault.
