This was my first thought when I seen the code. I did run the battery nearly dead trying to start the vehicle initially. But after charging the battery and clearing this code it did not return. Also my X does have comfort access so it has the key fob with a replaceable battery and a backup slot in the vehicle. I tried starting the vehicle with the key in the backup slot just to help rule out an issue with the fob battery.

I do believe the vehicle does need a battery in the future, it had a few slow cranks during the recent brutal winter but now that it has warmed up I have not had an issue with starting until today so I dont think the battery is causing the issue? I did also connect a charger when I was trying to diagnose the issue and this did not seem to make a difference with the no start issue other than the starter audibly spinning the engine faster.
