Solution:

Only have 1 driver installed at any one time.

His software is not Nissan Consult 3 Plus R2R version. He need to use a bridge tool to connect a non-original VCI device. Because the non-R2R software only supports the original VCI, this is due to the limitations of Nissan software.

Here is the method on how to use a third-party VCI with Consult 3 Plus non-R2R version.

 

The functions of the RLink X7 are becoming more and more powerful as you use it. To use non-R2R version software with Rlink X7, you need to use a cracked small tool (C3PTool) in combination with this software. Here we share the connection method and the fact that we successfully solved the problem and cleared the fault codes.
