The EEPROM Method

EEPROM is the abbreviation for electrically eraseable programmable memory (EPROM). It is a nonvolatile CMOS chip that stores data in computers and other electronic devices. It is programmed to store individual bytes which can be accessed via an address. Each byte could be one or zero. When a byte has been recorded to the chip it is activated. The bits are encoded into instructions when the byte is read.

When writing to an EPROM, the source and drain terminals are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it is able to reach the floating gate. This causes electrons to flow in to it and become trapped. The gate's contents to change from a zero to one. When the voltage is removed the gate is uncharged and the contents of the EEPROM are erased.

EEPROMs are commonly 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 especially important for ICs that are powered by battery, since a sudden loss of power could cause the chip to reset.

There are a few ways to reprogram an EEPROM however, the majority of them require that the car be in a specific state at the time. For instance, it might be necessary to disconnect the ECU from the battery, or remove the EEPROM and solder it to an test board. Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip.

It is a lengthy process, and it can be difficult to obtain the correct data. Most people choose to have their cars reprogrammed professionally instead of doing it at home.

A professional can complete this task swiftly, often within less than an hour.

Certain vehicles may require more time to complete the process to complete, which can be accomplished by connecting the device to the OBD2 port.
