are converted into instructions when the byte is read When writing to an EPROM the drain and source terminals are grounded A high voltage from the control gate tunnels into the silicon oxide before it is able to reach the floating gate This causes electrons to flow to it and become trapped The gates contents to change from a zero to a 1 When the voltage is cut off the gate is uncharged and the contents of the EEPROM 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 maintain the state of the system between power transitions This is essential for ICs powered by batteries since a sudden loss of power will cause the chip reset There are a couple of methods to reprogram an EEPROM However most of them require the car to be in a specific state It might be necessary for instance to disconnect the ECU and battery or remove the chip and place it on the test board Then the contents of the EEPROM can be read by an EEPROM reader and transferred to a different chip This can be a lengthy process and it can be difficult to get the correct data Many
