Where is Data Stored in a Control Module?: Notes

WARNING: This page does not describe the selected car, but rather 333 other vehicles, including the 2007 BMW Z4, 2007 BMW X5, 2007 BMW X3, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

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.
