I have have even reset the PCM an fuses it still did it then some how I put it in kph an it stoped doing it, so we will see apt to do diagnostic on Thursday. Thanks thoughFirst thing I would check are both ends of the battery connection. If all ok, hi need to have battery and alternator checked.
Please let us know what you find
I found if I plug into the 110 outlet on my dash it also sends it into battery save mode.
