Clearing Fault Codes
WARNING: This page is about a different car, the 2004 Mercury Marauder, 2004 Mercury Grand Marquis, and 2004 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
- Connect scan tool to Data Link Connector (DLC), located under left-side of instrument panel. Turn ignition switch to RUN position. Follow manufacturer's instructions for scan tool being used.
- The scan tool will retrieve DTCs again after clearing DTCs, and if any remain they will be displayed. Hard DTCs will be re-displayed after clearing DTCs since they cannot be cleared from RCM memory.
