Q: what are the B1 B2 ect. services? 95,000 miles on the car.
on 2009 Acura TL

It was working intermittenly for a while. Then the battery was disconnect for another problem, ever since then it won't even load the softeare. Just shoes message (check disc).

I can't open the back door!

The VSA light and a triangle with a exclamation symbol illuminates when I start my car. The car won't run right, until I turn the car off and restart it. Leaving the check engine light on. It also cuts off during down-shifting. Also, running the a/c for long periods of time, makes it run bad. Which also, makes the car cut off while driving. What could be causing these problems?
