Can not connect with nissan march k12 2003 mode. Because protocol issue l

The most common "protocol related" issues are:

• no power on ECU: engine does not started AND/OR key not at ON (II) position
• brake or bad contact of a signal wire in the diagnostic socket
• hanged adapter: need to be reset (unplug/plug back to the diagnostic socket)
• (partially) malfunction adapter ( https://incardoc.com/en-us/thread/Attention-Bad-Bluetooth-adapters-#post252 )
• your car have no or limited OBD-II support ( https://incardoc.com/en-us/article/what-cars-are-supported/ )

For the Nissan models without OBD-II support you might try conection via inner Nissan protocol Consult:
