Instrument Cluster EEPROM

The instrument cluster contains a data storage area that saves data even when you remove the battery power. This data storage area is called Electrically Erasable Programmable Read Only Memory (EEPROM). The instrument cluster uses this data storage area in order to store the following information:
^ Odometer information
^ Option information
^ Manufacturing information

The EEPROM area is an integral part of the instrument cluster microprocessor, and cannot be serviced separately.
