Saturn was the Rocky Balboa of the automotive world. Well, sort of. It was Rocky if the Gipper had gone into massive debt betting against Rocky, and then had to sell off Rocky's internal organs -- one at a time -- to pay his loan sharks. Saturn had everything going for it, including worldwide rebranding under the Saab and Opel names, attractive pricing, a bright future with the Ion and Sky, and all the best tech that GM had to offer. While fate may have intervened to cut Saturn's upward trajectory, the original L-series' sophisticated computer and the processes used to reset it remain the same.

Plug a scan tool into the Onboard Diagnostics, Series II port. You can find it hanging under the dashboard, just above the gas and brake pedals. Plug the scanner tool into the Saturn's OBD2 port, turn the car's key to the "on" position and then turn the scanner on. After the scanner boots up, select "ECM" -- engine control module -- from the menu. You may need to go through a couple of different menus to get to the engine control module.
2Select "Clear DTCs" -- diagnostic trouble codes -- both current and stored. "Current" DTCs indicate a problem that the car is experiencing now; you can clear the current code, but it'll come right back when you start the car unless you fix the problem that caused it. Stored DTCs are just that; they're problems that the car has experienced, but which are no longer actively affecting it.
3Write down any stored or active codes before you delete them. Those stored DTCs are there for a reason -- to give you early warning of intermittent problems before they become permanent ones.
