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 (E  lectrically P  rogrammable R  ead O  nly M  emory)
• EEPROM (E  lectrically E  rasable P  rogrammable R  ead O  nly M  emory)

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.
