Flash Electrically Erasable Programmable Read Only Memory
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2002 Mercury Sable, 2002 Mercury Mountaineer, 2002 Mercury Grand Marquis, 2002 Mercury Cougar, and 2002 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
Flash Electrically Erasable Programmable Read Only Memory (EEPROM) is an Integrated Circuit (IC) within PCM. This IC contains software code required by PCM to control powertrain. EEPROM can be electrically erased and then reprogrammed without removing PCM from vehicle. If a software change is required to PCM, PCM can be reprogrammed through Data Link Connector (DLC) using scan tool.
