In the case of reading using a serial tool, you need to find the diagnostic connector (OBD2) present inside the car to map before you can proceed with the reading of the original file.Īlientech has developed two serial programmers which perform the previews task: Then you’ll have to read data stored inside the chip using an EPROM programmer Alientech trades Galep in this regard. In the first case you need also the equipment for welding/unsoldering memory chip on the printed circuit board of the unit, so you must remove the ECU from the vehicle and open the box which protects the electronic board. By connecting a tool for reading data from the microcontroller.By connecting a tool for serial reading to the diagnosis connector (OBD2).By unsoldering the memory chip (EPROM) and reading the data stored.The reading can be achieved in three ways: BDMpro, lettore for comunicazione con microcontrollore.Generally you need a tool to read the file stored inside the memory of engine control unit.Īlientech produces and trades the following devices: To simplify the explanation will be described only the tools developed by Alientech Srl. Each part of this document describes in detail all the steps you need to understand before proceeding with the following part.
