Diagnosis by Symptom Index Directions
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
- Using the Diagnosis by Symptom Index, select the Concern/Symptom that best describes the condition.
- Refer to the routine indicated in the DIAGNOSIS BY SYMPTOM INDEX .
- Always begin diagnosis of a symptom with:
- preliminary inspections.
- verifications of condition.
- checking the fluid levels.
- carrying out other test procedures as directed.
- Begin with the Electrical Routine, if indicated. Follow the reference or action required statements. Always carry out the on-board diagnostic tests as required. Never skip steps. Repair as required. If the concern is still present after electrical diagnosis, then proceed to the Hydraulic/Mechanical Routine listed.
- The Hydraulic/Mechanical Routines list possible hydraulic or mechanical components that could cause the concern. These components are listed in the removal sequence and by most probable cause. All components listed must be inspected to ensure correct repair.
NOTE:
Not all concerns and conditions with electrical components will set a 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 Routine listed.
