I used CG FC200 to test my audi bosh edc17cp14 tc1796, but it prompted me connection failed,and let me check if the connection is correct. I also tested on other ECUs, all failed as well.

You didn’t connect the FC200 to your ECU correctly. The brown and purple wires were not connected.
Please follow the wiring diagram in the CG FC200 software to connect again.
