I have a 2016 titan xd with a 5 L cummins. When I hooked up my hpv12 to it only the tach and ect worked. If I buy 4 credits, will I get full function on all level to check codes and write changes?
I need to check codes, add fuel at cold weather start up and check soot loads in the dpf. I know these trucks are rare and Nissan has stopped making them but I would like to be able to tune this engine and possibly the trans.
