WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

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 article.
After determining the possible "system(s)", refer to the appropriate article in this service information to identify the worn or damaged "components".
After identifying the 'components", identify the "cause" of the failure.
