tire size and odometer
 

I am moving up from the stock 14" to 15" do i need to reset anything? And my odometer and trip stop workin how can i fix this??

does the speedometer still work?
If just the odometer portion has quit, the stepper motor on the speedo cluster is bad.
When changing tire size there is nothing to reset to compensate for the difference

yes the speedometer works just the odometer and trip dont.
