Let me run down my recent OBC message. Parked the car outside when I got home from work. I was about to go to bed so I moved the car into the garage and noticed that the trans program message appeared. The only thing I have noticed the past couple days was a squeal from what I thought was the belts that I have been waiting to get looked at. Could this be related?
I researched that this might be caused by a battery getting low. It is starting to get cold here in Nashville. If I checked the battery voltage from the OBC would this give me an indication of the need to change the battery.
