After trying many many times in the last 5 months I was able to get the Service wrench reset. Don't know what I did different but it finaly worked. Am getting ready to take a trip over the 4th of july from Tampa Florida area to Indianapolis Indy. All said and done it should be around 2500 miles total. Going to change oil and filter right before I go, just replaced waterpump and coolant a few weeks ago. Hoping no unexpected issues. Happy Motoring.
