Do Not Cure the Symptom and Leave the Cause

Lowering the pressure in a front tire may correct the condition of a vehicle leaning to one
side, but it does not correct the original condition.

Be Positive the Cause is Found

Double check findings.
What caused a worn component?
A loose transmission or engine mount could indicate that other mounts are also loose.

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 performing certain tests before others.
Elimination of checking huge portions of a system by performing simple tests.
Certainty of narrowing down the search to a small portion before performing 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.
