The other day got a pressure light, but it flashed for 20 seconds first implying there is a problem with the signal (broken or dead TPMS). Every day it came on. Got a new one thinking maybe one of the batteries were dead and went to the wheel shop to get the dead one replaced. The scanner got a signal from all 4 TPMS and the pressures were all ok. The light was still on so we plugged into the serial port and it reported all was ok and the light went out. Drove to a few places after that with no problems, then later on the way home, it came back on, flashing first like before. Any suggestions? Could it have to do with the fact that I have an aftermarket tune?

Don't all jump in at once! Lol. Anyway, as an update, went to Nissan today and their sensor reader couldn't get a signal from two of my TPMS'. So that's where I'm going to start.
