Check engine light on
Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.

The "service vehicle" light is a problem with the Body Control module, not the Powertrain Control module and most of the generic code readers won't be able to access those codes. You will likely need a professional scan tool.
