Where is Data Stored in a Control Module?: Notes

The control modules used in our vehicles store data/information on one of the following:

• EPROM (Electrically Programmable Read Only Memory)
• EEPROM (Electrically Erasable Programmable Read Only Memory)

in essence these devices are similar to the harddrive of the PC (P  ersonal C  omputer) that many of us use daily to store the images and documents/files of information.
