Inspection and Verification

  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage.
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  4. If the cause is not visually evident, verify the symptom and refer to the «SYMPTOM CHART: EXTERNAL CONTROLS»(ref-635244-S08010535252014070200000) .

DTC DESCRIPTION

Symptom Chart: External Controls

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices.

REFER to: DIAGNOSTIC METHODS .

In most circumstances the PCM sets a DTC to help guide with the diagnostics. Refer to the DTC CHART before using the Symptom Chart. The Symptom column lists the vehicle condition. The Possible Sources 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 cause 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.
