For NVH concerns, it is necessary to classify the customer's concern into one of the 3 categories: noise, vibration or harshness. The reason for this is that a customer concern may consist of a combination of symptoms involving noise and vibration, or vibration and harshness. In cases where there are combination symptoms, you, the technician, need to know which diagnostic path to follow: noise, vibration or harshness. For example, if a customer has a concern involving a noise and a vibration, determine that it is vehicle speed-related, and follow the vibration diagnostic path.
