Clearing Diagnostic Trouble Codes: Notes
WARNING: This page is about a different car, the 2001 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not disconnect vehicle battery to clear DTCs. This will erase operating information from Keep-Alive Memory (KAM). To clear KAM, disconnect negative battery cable for at least 24 hours.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
