WARNING: This page does not describe the selected car, but rather 29 other vehicles, including the 2007 Mercury Mountaineer, 2007 Mercury Monterey, 2007 Mercury Montego, 2007 Mercury Milan, and 2007 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.

All diagnosis begins in the SYMPTOM CHARTS article with QT Step 1: 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 Step 2: 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 Step 3: No Diagnostic Trouble Codes (DTCs) Present Symptom Chart. If no PCM DTCs are present and the vehicle symptom is not listed in Step 2: No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index, the technician should go to the appropriate service information article to continue diagnosis.
