Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode that helps beginners while experienced technicians can use Expert Mode.

The EEPROM Method EEPROM is an acronym for electrically erasable memory that is programmable (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It is programmed using individual bytes, which can be accessible using an address. Each byte can be either a 1 (or one of the numbers). If a byte has been recorded to the chip it is activated. The bits are then decoded into instructions when the byte is read. When writing to an EPROM, the drain and source terminals are grounded. A high voltage channeled from the control gate passes through the silicon oxide to the floating gate which causes electrons to flow into it and then become trapped. The gate's contents to change from a 0 to 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased. EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless system components. They can also be used to maintain status between power changes. This is important for ICs powered by batteries because a sudden loss in power can 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 particular state. It might be necessary, for example to disconnect the ECU and battery or remove the chip and place it on the test board. The contents of the EEPROM chip can be read by an EEPROM Reader and then copied onto another chip. It can be a lengthy process, and it is difficult to obtain the correct information.
