service vehicle soon light

I have the same problem except it only comes on at night time. There is a connection between the service vehicle soon light and the headlight - DRL light system.

The service vehicle soon is really like ABS system code. I don't think you have the correct scanner for that. You can't use a Check Engine Light scanner for that type of code it is a different type of Computer. So, have a shop with the proper scanner check your car out. http://repairpal.com/oldsmobile-repair-in-salina-oklahoma
