So i have a 2017 nissan versa that recently had a transmission replaced under warranty. Afterwards I went to have the emissions done and they told me that they wont do it because my engine light isn't coming on. I dont understand maybe my car is in a special mode? Because the a/c doesnt turn on either. However when I disconnect, and reconnect the battery the engine light works until I start the car. Then it goes off and never comes back on until I disconnect the battery. Normally it should come on when you put the key in and turn it to ACC but it doesnt even turn on for that. And for that reason I cant get the emissions done. If it's a special mode how do I take it out or fix it?
