When writing into an EPROM the drain and source are grounded A high voltage channeled through the control gate travels through the silicon oxide to the floating gate which causes electrons to flow through it and become trapped The gates contents to change from a 0 a 1 If the voltage is removed from the gate it becomes uncharged and the EEPROM contents are erased EEPROMs are often used to store calibration coefficients for sensors bootloader configurations and also the status of remote keyless system components They can also be used to preserve state between power transitions This is

require the vehicle to be in a certain state For example it may be necessary to disconnect the ECU from the battery or to take the EEPROM out and solder it to the test board The contents of the EEPROM
