I have a 1990 Oldsmobile Delta 88, While I was driving down the highway today my car beeped 5 times. It sounded exactly like I turned the key to the on position to start the car...but I was driving on the highway. Seat belt was on, brake was fine, no dash lights, car ran fine while it was beeping. What could case the car to beep while driving?
Also where on the transmission are the ECM grounds located?
