Identify the Condition

NVH usually occur in four areas:

• Tires
• Engine accessories
• Suspension
• Driveline

It is important, therefore, that an NVH concern be isolated into its specific area(s) as soon as possible. The easiest and quickest way to do this is to carry out the Road Test as outlined. To assist in the diagnosis and testing procedure(s), use a suitable approved NVH diagnosis tester.
