Abstract: PURPOSE: A programming system of an ECU(Engine Control Unit) for a vehicle is provided to promote the common use of parts for an ECU by mounting the ECU including an operation program and mapping data in a memory in a vehicle and installing the operation program and mapping data selectively according to input key codes. CONSTITUTION: A programming device of an ECU consists of a start key(10), an IC(Integrated Circuit) chip(20), a start key assembly(30), an interrogator(40), a communication unit(50), and an ECU(60). The IC chip is mounted on a holder unit(11) of the start key. The IC chip includes a communication circuit for transmitting/receiving RF(Radio Frequency) signals and a memory having key codes. The start key assembly feeds power to the interrogator, the communication unit, and the ECU when a driver inserts the start key to turn on main power. The interrogator transmits a signal requiring a key code to the IC chip and feeds a key code signal to the communication unit by converting the radio key code signal into a wire key code signal. The interrogator includes an antenna(41) for transmitting/receiving radio signals. The communication unit transfers the wire signal to the ECU by filtering the signal. The ECU deletes unnecessary elements of operation software and mapping data in a memory according to the key code and controls engine start with the other operation software and mapping data.
