More than three years ago, I purchased a Bluetooth ELM327 OBD2 Auto Car Diagnostic Scan Tool.
Since that time, I have been trying to make it work on my Nissan Tiida (Versa) using all the software utilities I can find on Android market with bad luck. I have also tested it on Nissan Qashqai, but still did not work. It worth mentioning that I have tested the tools on may models of other car makers, and it worked flawlessly. After some research I found out that Nissan have made some protection on the used protocol so Engine Control Unit can only be interfaced to ConsultIII systems used at Nissan service centers.
Recently, with the introduction on new OBDII software tools, I have installed many of them, but still with bad luck, so I made a new deeper research and found that some people used the following a tool called "Car Gauge Pro" and it works fine when setting the protocol to "14230-4 (Fast Init)". So, I tried this set up and finally got it working.
Note: Both the OBDII scanner and the software have to support "14230-4 (Fast Init)" protocol
I. Download and install "Car Gauge Pro" from Google play store
II. Plugin your OBDII scanner into car OBD port.
III. Get your phone paired with OBDII scanner through bluetooth.
IV. Start "Car Gauge Pro" and do the following:
