Diagnostic Charts

Charts are a simple way of expressing the relationship between basic logic and a physical system of components. They help discover the cause of a condition in the least time. Diagnostic charts combine many areas of diagnosis into one visual display:
^ probability of certain things occurring in a system
^ speed of checking certain components or functions before others
^ simplicity of carrying out certain tests before others
^ elimination of checking huge portions of a system by carrying out simple tests
^ certainty of narrowing down the search to a small portion before carrying out in-depth testing

The fastest way to find a condition is to work with the tools that are available. This means working with proven diagnostic charts and the correct special equipment for the system.

A number of NVH diagnosis testers are suitable for use on Ford vehicles. These are designed to locate mechanical noise, wind induced noise and squeaks and rattles. They are particularly useful for locating engine noises, worn wheel bearings, tire noise, suspension squeaks and plastic component rattles.

The equipment is available from the FSE/Rotunda program.
