I have Launch X431 Master that can diagnose Nissan and Ford USA up to 2012, but always saying communication error with ECU when I use OBDII 16 pin socket on them, does that means it cant diagnose these vehicles?
If It can work on Ford USA can it reprogram the key?
All of the older X431-Masters use a TF Flash Memory card that must have the CAN BUS files and the Super-16 files to support the matching Super-16e
CAN-BUS OBD2-16 pin connector. You may require to REFORMAT existing Flash memory card and only download the CAN-BUS files and Super-16 first.
Then you can try to download your previous history diagnostics software back onto the Flash memory card again.
