Flash Electrically Erasable Programmable Read Only Memory (EEPROM)
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2016 Lincoln Navigator, 2016 Lincoln MKZ, 2016 Lincoln MKX, 2016 Lincoln MKT, and 2016 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
The flash EEPROM is an integrated circuit within the PCM. This integrated circuit contains the software code required by the PCM to control the powertrain. One feature of the EEPROM is that it can be electrically erased and then reprogrammed through the data link connector (DLC) without removing the PCM from the vehicle.
