Welcome, I'm Chris (aka-Moose).

  • WORK TIME, I am here 7 days a week but not all hours of the day, do not worry I will respond.
  • FEES, I am a user of the website like you, not an employee. Any fee or account questions need to be addressed to the website.
  • PHONE CALLS, I will never offer nor ask you to pay more for a call, calls and memberships are pushed by the website.
  • UPLOADED LINKS, if I upload dropbox links, without the phone app use the box on the top right for direct download.
  • RATING ANSWERS, please let me know what you need from me so you are pleased with my answer.

As long as all the power and ground wires to the ECM are good, the data link connector power fuse is good. Then this communication issue will be to blame on damaged communication wires or another bad module affecting the communication wiring circuit. Can you do wire testing and diagnosis.

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5-star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris

What Customers are Saying:

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
