Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you!
When communicating through the OBD2 port, Key on or Engine Running is fine. As for why he was unable? Lets try something. Do you have a Auto Zone near you? They offer free scans. If you swing by there and see if they can communicate with your computer. If they can, take the print out from auto zone saying no codes showing that communication is fine, it could be the inspection stations equipment. If your in California, Auto Zone does not offer this. But normally I would like to try another scanner before I condemn the OBD2 port. It's extremely rare for it not to work!
Do you think you can do that and return and let me know how you made out?
Your welcome.. Please return and let me know how you make out!
