Title: EDC15C5 JTD ECU clone Post by: vgeorgiev on April 25, 2014, 04:19:11 AM Hi all,
I manage it. Here is how I did it: 1. Put the ECU on the bench and provide it with power. You can connect K line as well.

It seems that the car used this ecu went more than 500,000km. Unidiag log showed me 0xff 0xff 0xff.

Bottom left on the back side. (http://i105.photobucket.com/albums/m218/vrgeorgiev/IMG_0002_zps2eb53614.jpg) 4. Solder wires to SCL, SDA and VCC. Connect to programmer Note: When read/write the EEPROM DO NOT connect ECU power lines to power supply. You can use any EEPROM programmer you want. I do not have a COM port on my PC. That's why I used DIY (USB<->TTL<->AVR<->EEPROM) programmer. Do not ask me :) You can use JDM programmer with ICPROG or PonyProg software.

Read content of EEPROM. Here is what I got: http://1drv.ms/1jeAa4D (http://1drv.ms/1jeAa4D) I guess the odo is located at 0х28 0х29 0х0а. HW version is located from 0x5d to 0x65. Stored key numbers are located from 0x1ea to ox1f8. (http://i105.photobucket.com/albums/m218/vrgeorgiev/dump_before_zps56404489.png) 6. Download the new dump from here (http://www.techno-diag.com/pdf/index.php?dir=Immodatabase%2FIMMOOFFbins%2FFiat%2F) or here (http://1drv.ms/1jeDOvq). The trick is to set 0x00 at adresses from 0x1ea to ox1f8. (http://i105.photobucket.com/albums/m218/vrgeorgiev/immo_reset_zpsf6e925cc.png) 7. Program the new dump to the EEPROM and check the result. Like a virgin :) Next key will be programmed automaticaly. https://www.youtube.com/watch?v=4G5yAHhq1V4 (https://www.youtube.com/watch?v=4G5yAHhq1V4) (http://i105.photobucket.com/albums/m218/vrgeorgiev/immo_status_after_zpsad9f003a.png) The odo is clear now. If you do not want to clear the odo just use your dump and reset from 0x1ea to ox1f8. (http://i105.photobucket.com/albums/m218/vrgeorgiev/odo_after_zpsc3467b26.png) 8. Put new ECU in the car and ignition on. https://www.youtube.com/watch?v=yg6TOrmjOdo (https://www.youtube.com/watch?v=yg6TOrmjOdo) |
