is written on the chip it is activated and when it is read the bits are decoded as instructions When writing to an EPROM the drain and source terminals are grounded A high voltage channeled through the control gate travels through the silicon oxide to the floating gate and causes electrons to flow through it and then become trapped This causes the gate to change its contents from a zero to a 1 If the voltage is removed the gate is uncharged and the contents of the EEPROM are erased EEPROMs can be used to store calibration coefficients of sensors bootloader configurations and the statuses of remote keyless system components They can also be used to maintain state between power transitions This is essential for ICs powered by batteries since a sudden loss of power will cause the chip to reset There are a variety of methods to reprogram an EEPROM however the majority of them require that the vehicle be in a particular state at the time It may be necessary for example to disconnect the ECU and battery or remove the chip and place it on an test board Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip This can be a lengthy process and can
