I purchased AE a few months ago. I first connected it to my truck and everything worked fine. Randomly the live data meter readings started reading all zero values for me. I called AE and they worked with me and determined that I had a bad connector so they shipped me a new one. I tried hooking it up to my truck and the live data meters are still only reading zero. I also can't perform any KOER/KOEO tests. The strange thing is I can use the software on a couple other trucks perfectly. What could be the problem with my truck?
