1. I'm trying to connect to my car's ECU but I get an error message "Unable to open COM1".

The COM Port number that the NDS II software is trying to use is invalid. A COM Port number was assigned to your adaptor by the driver at the time of first installation. This COM Port number will need to be entered in the NDS II software under Settings->Communication.

If you don't know what Port number was assigned to your adaptor you can find in Device Manager under "Ports (COM & LPT)".


2. I'm unable to connect to BCM, TCM, ABS or SRS control module but I can connect to my ECM (engine ECU).

Some Nissan models may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. NDSII does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol. The GI section of Service Manual usually identifies what communication line is used for each module.


3. I can not login to members section to generate my activation key.
