Clearing Diagnostic Trouble Codes
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
After repairs are performed, use scan tool and manufacturer's instructions to clear or erase DTC from PCM memory.
