The EEPROM Method

The EEPROM is an electrically erasable read-only memory programmable (EPROM). It is a permanent CMOS chip that stores data in computers as well as other electronic devices. It is programmed to store individual bits of data that can be accessed using an address. Each byte could be one or zero. When the byte is written on the chip, it becomes active and, when it is read, the bits are decoded into instructions.

When writing to an EPROM the source and drain terminals are grounded. A high voltage from the control gate passes into the silicon oxide before it gets to the floating gate. This allows electrons to flow to it and become trapped. This causes the gate to alter its content from a zero to a 1. When the voltage is cut off the gate ceases to be charged and the contents of the EEPROM are erased.

EEPROMs are typically 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 the state of the system between power transitions. This is particularly important for ICs that are powered by battery, since a sudden power loss will cause the chip to reset.

There are several methods to reprogram an EEPROM. However, most of them require that the car to be in a certain state. For instance, it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to an test board. Then the contents of the EEPROM can be read using an EEPROM reader and transferred to a different chip.

In most cases, a key or fob has to be programmed in order to be able to communicate with the car before it can be used to start the engine. The electronic keys found in the majority of newer cars are equipped with upgraded transponders that require a special programer to function properly. Professionals can accomplish this task efficiently, often within less than one minute.

Some cars may need more time to complete the process to complete, which can be accomplished by connecting the device to the OBD2 port. Certain cars might require EEPROM programming, which can take several days.
