Lol. You like to program ? RAM? No man just change the RAM and Enjoy.
I'm having problems with my cable. When I connect to the usb port it is recognized by the pc, the green after flashing is fixed. But when I try to make a diagnosis to any car he says he finds nothing. How can I fix?
After jerking around with my lexia conecting only with pc but not with car tested all the above methods but nothing . At first i didnt have 5 volts on pic and relays not working i managed to repair that after same thing relays dont working. Started reprograming all the chips one by one everthing ok with the chips. Finaly tried to reprog 25x80 it turned out to be the problem faulty eprom. Got an old broken laptop with bios eprom 25x80 reprogrammed with the file posted here and voala . Works like charm. Thanks to all participating in this post

After conecting to vehicle lexia stopped working. Came home and stared reprograming all the mcus again.Everything ok except the 25x80 eprom which had memory changed. Reprogramed again with the file posted here and tested on the bench, relays started clicking again everthing ok , removed power suply reconected again same thing stopped working , everything okk except relays dont click. Reprogramed the 25x80 again with seeprog, put software write protection and lifted pin 3 and conected with pin 4 and everthing works like charm tested on three vehicles several times still havent tested CAN VAN vehicle thou.

Solved with re soldering of the all components on the boards. Thanks to everyone for help.
Yesterday I had a problem,which is slightly different from other.The interface is not working but was able to run software.So, RAM memory and USB device was correct.Relays did not want to clicking.That two parts I replaced it with one working interface and again everything is ok,without any MCU programming.Best regards.
