Section 3: Symptom Charts

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2009 Mercury Mountaineer, 2009 Mercury Milan, 2009 Mercury Mariner, 2009 Mercury Grand Marquis, and 2009 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

All diagnosis begins in Section 3 with QT Powertrain Control Module (PCM) Quick Test. If the PCM Quick Test is completed and no diagnostic trouble codes (DTCs) are retrieved, the technician is directed to the No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index  . The No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index contains the list of symptoms addressed, and directs the technician to the appropriate chart in the No Diagnostic Trouble Codes (DTCs) Present Symptom Charts  . If no PCM DTCs are present and the vehicle symptom is not listed in the No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index, the technician should go to the appropriate Diagnostic article part to continue diagnosis.
