I came home yesterday and the neighbors son was changing the battery in her 2001 ml350. afterwords the asr esb light was on. I searched and it looks like it could be a problem with brake switch but i also saw a thread that asked if someone had changed the battery and the result was a light on. what would cause this?

The steering angle sensor must be re-synchronized by going from lock to lock several times.

thanks for the responses, She bought the truck used a few years ago and the dealer she got it from promised her a manual but never came through. Is the procedure listed here?
