Description
OE90C2620 is specially designed for FIAT motor
company cars. This chip allows to build a
complete diagnostic system using a PC or directly
in small device with LCD display. Some other
brand like Alfa and Lancia can be tested. All
diagnostic mode are implemented . Some
commands are implemented to allow direct access
to different ECUs. This chip is partially plug play
compatible with mobydic2600 Hardware and PCB.
