Hi I'm Kevin the engine system service light will come on if the vehicle ECU( computer that controls engine) picks up on a problem with the engine . Most problems are emissions related and won't cause any problems to drive if the car thinks the fault will cause damage to engine it will limit power output . The only way to read what is causing fault is by plugging car in using a diagnostic scanner this will give a fault code relating to where the car thinks the fault lies and will allow further testing of component to confirm fault
