Hello all,
When trying to connect to an ECU in the car, the message "Failed to read test echo from the FTDI device" occurs at any baud rate or init.
I've spent quite a large time trying to understand why this happens.
The cable I am using the obdlinksx:
https://www.amazon.com/ScanTool-OBDLink-USB-Professional-Diagnostics/dp/B005ZWM0R4*I also have another cable from a company that specializes in the tuning of the cars I have tried to read. Funny thing is that cable is just a relabeled obdlinksx (the FTDI chip is the same: ft230xq; I have not seen any information against or for this chip with Nemoto)*
**I also have a genuine VCDS hex-net but understand that does not function with Nemoto
***Both cables can use other software to connect to the ECU on the cars, VCDS connects flawlessly with the hexnet so not an OBD port issue.
I have verified that the drivers are installed from the FTDI website.
I have attached screenshots of the device manager and Nemoto screens.
When connecting I have the key in and ignition on. The cars/ecus I have tried to connect to are B5 S4(Various ECUs and cars), B5 A4 2001 (M and CH ecu don't know the numbers off the top of my head), and B6 A4 (8E0909518AF and 8E0909518AK) all to no avail.
I have tried restarting the Nemoto software, unplugging the lead, removing the fuses for instruments, unplugging the cluster, and redownloading from the software.
Please advise and thank you in advance.
