Diagnosis By Symptom Index Directions

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Use the Symptom Index to select the Concern/Symptom that best describes the condition.
  2. Refer to the routine indicated in the DIAGNOSIS BY SYMPTOM INDEX .
  3. Always begin diagnosis of a symptom with:
    1. preliminary inspections.
    2. verification of conditions.
    3. checking fluid levels.
    4. carrying out other test procedures as directed.
    4. NOTE: Not all concerns and conditions with electrical components will set a Diagnostic Trouble Code (DTC). Be aware that the components listed may still be the cause. Verify correct function of these components prior to proceeding to the hydraulic/mechanical components listed.
    NOTE: When the battery is disconnected or a new battery is installed, certain transmission operating parameters can be lost. The Powertrain Control Module (PCM) must relearn these parameters. During this learning process, you may experience slightly firm shifts, delayed or early shifts. This operation is considered normal and will not affect the function of the transmission. Normal operation will return once these parameters are stored by the PCM.
  4. Follow the reference or action statements. Always carry out the on-board diagnostic tests as necessary. Never skip steps. Repair as necessary. If the concern is still present after the electrical components have been diagnosed, proceed to the hydraulic/mechanical components listed.
  5. The list contains only possible hydraulic or mechanical components that may cause or contribute to the concern. These components are listed in the removal sequence and by most probable cause. All components listed must be inspected to make sure repair is correct.
