Hi there:

The Service (or Service Engine) light is a warning light that is connected to the engine control unit (ECU) of a vehicle. The ECU is the brain of the car and monitors a number of systems, including mileage, engine temperature and performance and the efficiency of the entire system. There are scheduled intervals for service; and after the service has been completed, the warning light can be manually reset. If you look inside your glove compartment there is most likely a vehicle owner manual. The instructions for resetting the service light should be in that manual. If you complete those steps and the light is still on, have a mobile mechanic from our team complete a service light is on inspection. This will allow us to download any error codes trapped in the ECU and determine why the light is on.
