Changing battery re tune?

[Big Mike 74]

This is probably a dumb question but if I change the battery in the car is it going to need to be re tuned.?

Nope. The tune is Not affected.

The car will need to potentially relearn trims, shifting, and a few other things though so take it easy for a few days so everything learns properly.

make sure the battery monitoring system is reset to learn the new battery parameters, otherwise it may not charge correctly.

How do you reset it?

The dealer or a shop with IDS software has to do it. Not a DIY thing, as it is not part of the KAM reset.
