i tried searching without any luck, after i changed the car battery, the on board computer is stuck on mpg now and i can no longer change it. windows have been reset but i have not found any other things that had to be done after changing the battery, anybody else have this problem or solution to fix this. thanks!

 

I can't help but I have a similar problem. Dealer changed the battery and now the steering wheel control to change radio stations is not working.

Mine is an 03 ES330.

 

guess i am not the only one, hopefully somebody has an easy fix for us
