Symptom Chart

WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Refer to the wiring diagrams for connector numbers stated in the pinpoint tests.

NOTE: If multiple symptoms occur refer to PRINCIPLES OF OPERATION for switch system power (SSP) feature. A failure of an SSP feature, an individual, or all SSP relays will cause multiple failure symptoms and DTCs. When diagnosing multiple symptoms and DTCs, it is essential to determine if all the symptoms and DTCs are controlled by the SSP feature.
