Stability control question
 

Traction control and rpm guage
Just had fired up my car today to get ready for the season
Had the battery disconnected for about 6-8 weeksover the winter
Just got an error that the stability control needs service
After warming up i noticed the the rpm guage did not work either

I take it it was due to the battery disconnect. Does any one know if This will reset or will I have to delete or get the codes cleared? Did any one experiance this problem

Maybe I should have trickle charged it?
