Diagnostic Theory
The shortest route to an accurate diagnosis results from:
System knowledge, including comparison with a known good system. System history, including repair history and usage patterns. Condition history, especially any relationship to repairs or sudden change. Knowledge of possible sources. Using a systematic diagnostic method that divides the system into related areas.
The diagnosis and correction of NVH symptoms requires:
A road or sytem test to determine the exact nature of the symptom. An analysis of the possible causes. Testing to verify the cause. Repairing any symptoms found. A road test or system test to make sure the cause has been corrected or brought back to within acceptable range.
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" diagnostic technique.This diagnostic method divides the problem into related areas to correct the customer concern.
Verify the "symptom". Determine which "symptoms(s)" can cause the "symptom" using the diagnostic tools described in this section. After determining the possible "system(s)" , refer to the appropriate section in this manual to identify the worn or damaged "components". After identifying the 'components" , identify the "cause" of the failure.
