Symptom Chart

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in SERVICE INFORMATION for information about these practices.

In most circumstances, the PCM sets DTCs to help guide with diagnostics. Refer to the DTC CHART  before using the symptom chart. The Condition column lists the vehicle condition. The Source column lists a detailed vehicle condition. The Action column lists the action to be performed to determine the cause of the condition. Each action lists the components that can caused the system and the individual components in that system. The components are listed in order of disassembly. Use the list of components and the required action to focus on disassembly inspections for the root cause of the concern.
