Q: Battery change. Do you do computer reset after battery change?

asked by on November 18, 2016

Will all data still in memory? Do I still need to go to the the dealer to reset the computer?

My car has 48000 miles.
My car has an automatic transmission.

Hi there:

The ECU contains a small battery inside of it that acts as a back up when the battery drains or is removed; which ensures that data is not wiped away when the battery is replaced. There is no need to reset the computer per say, but if you had any error codes that indicated a problem existed; then you’ll need to have a professional mechanic complete a check engine light inspection.
