Flash Electronically Erasable Programmable Read Only Memory (EEPROM)

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2022 Ford F-550 Super Duty, 2022 Ford F-450 Super Duty, 2022 Ford F-350 Super Duty, 2022 Ford F-250 Super Duty, and 2021 Ford F-550 Super Duty. 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 flash EEPROM is that it can be electronically erased and then reprogrammed without removing the PCM from the vehicle. The reprogramming is carried out through the DLC.
