Thanks, I have seen that post. If I have understood this post correctly I need USB cable with FTDI chip? I have tried cable (made from Nokia CA-35 cable) without FTDI chip and it won't detect ECU.
I can't find anywhere wiring diagram for LC-01 diagnostic cable so tried combination RX TX GND and TX RX GND (didn't connect nothing to 12v socket)
I have successfully made cable for diagnostic. Unfortunately my LC01 is broken. I want to replace it with LCS-V05E. Since cable connector is not same I need to re-wire connector.
Can someone be so kind help me to figure out those wires with question marks? Here is the photo of LC01 connector:
