Diagnostic Procedure Overview

DIAGNOSTIC PROCEDURE OVERVIEW

Qualifying the symptom by the particular sensation present can help narrow down the cause. Always use the "symptom" to "system" to "component" to "cause" diagnosis technique. This diagnostic method divides the problem into related areas to correct the customer concern.
- Verify the "symptom".
- Determine which "system(s)" can cause the "symptom" using the diagnostic tools.
- After determining the possible "system(s)", refer to the appropriate Component or System to identify the worn or damaged "components".
- After identifying the "components", identify the "cause" of the failure.
