Warning Lights on When ECU Scanner Plugged In
I've been having this really weird problem for the past two weeks with my Z and I can't seem to figure it out, so I figured I would post it here in hopes of getting some help.
I recently installed a cat-back exhaust and a set of high flow cats. The car was in my garage up on jack stands for a few days with the negative battery cable disconnected. After the install was complete I reconnected the cable and the car ran fine. A few days later I plugged in my OBDII scanner to mess around with the torque app and I immediately noticed the airbag light, the VDC Light and the traction control light were all illuminated. I turned the car off and back on and the lights went off. Several minutes later they came back on. I turned the car off, pulled out the scanner and started the car and the lights never came back on. That is until I plugged the scanner in. I use this scanner on a few other cars and confirmed it was working fine in them. It only has issues when plugged in to the Z. I have briefly used it in the past in the Z with no issues. While plugged in I scanned for any fault codes, but none were found. When the scanner isn't plugged in the car runs fine and the traction control / VDC works without any issues. I'm not sure what to do about this. I've also read that for reasons unknown, the brake fluid can set off a number of dash lights, so I checked that and its fine. Again, this only happens when the scanner is plugged in. Any and all help will be most appreciated.

You have done all the appropriate troubleshooting. It's the scanner. Obviously it's not playing nice with the Z ecu.
Scanner plugged in = problem Scanner not plugged in = no problem. Get a different one. I use torque app as well with a $17 ebay Bluetooth plug in. No problems

I just borrowed a coworkers scanner. He happened to have it in the glove box of his car. I'm gonna give it a shot tonight when I get home. I seriously hope it my stupid $20 scanner and not something with my car.
