I suggest you buy a $20 OBD-II code reader off Amazon; you can get one that has display, or one that blue tooths to your smart phone. Then you can google the error code to determine issue by chassis/ engine.
Hi I got a 1997 Gulfstream frienship 102, and code reader will not work on it but try disconnecting the neg batter cable for a few minets and re coneting, it that may reset it.
