What city and state do you live in? Maybe someone is near you can take a look?
Yes, my nissan dealer isnt too friendly. The last visit they were nicer, but between the way they behave and their high prices Im likely to never own a new nissan again.
Depending on your state you may get by with lights on your dash. Other than not knowing your speed all your brake related features should be disabled like traction control, skid, anti lock brake and force distribution. So basically you have regular brakes before computers were involved. You should notice the cvt behaves differently too as it uses the abs sensor to know wheel speed to better select the cvt ratio for speed, throttle, etc.
Some states stick a sensor up your tail pipe, others plug a computer into your computer port, others just check things.
