Nissan DataScan II (NDSII) is an essential diagnostic software for Nissan and Infiniti vehicles. It allows you to read trouble codes, view real-time engine parameters, and perform critical functions like idle air volume learning.

Open the software, go to Settings > Communication , and select the matching COM port. Set the baud rate (usually 9600 or 10400 for Consult II).

However, one of the most common hurdles users face is the process. Many users download the software, but without a properly generated and installed activation key, NDS2 remains in "Demo Mode"—severely limiting its functionality.

If your diagnostic laptop is air-gapped (never connected to the internet), use this method.

Return to the NDS II software's Activation window and into the appropriate field . Click the Unlock button .

Log in to the Nisscan Member's Area using the credentials provided in your purchase confirmation email.

Plug the 16-pin OBD2 end of your cable into your Nissan's diagnostic port (usually located under the steering column). Connect the USB end to your laptop.

Follow these steps to get the software onto your PC before activating it.

To activate , you must first generate a unique Registration Code from the software itself and then exchange it for an Activation Key on the Nisscan website. Standard Activation Steps
