Sorry for the late reply I was away on vacation

I have the battery tender connected directly to the battery. That's how this whole thing started as I loosened then removed the nut on the negative post to put on the battery tender lug I temperarily lost connection between battery and cable.

I did try resetting it with the battery tender disconnected and still no luck. One thing I noticed is that my battery voltage was only 12.5 volts after I unplugged the tender. I would have expected the voltage to be higher.

Also, I was using the tool connected to the OBD port however will try resetting using the connection under the hood as Hornedfrog mentioned.
