How do you reset the Service Engine Soon light on a 1992 Tempo GL?

1. Turn the ignition switch to the "On" position, but do not start the engine.

2. Locate the diagnostic connector under the dash on the driver's side. It is a black plastic connector with a 16-pin plug.

3. Connect the negative battery terminal.

4. Short pins 1 and 16 for no less than 1 second; then open them.

5. Turn off the ignition, wait at least 10 seconds and then restart the engine. The indicator light should now be turned off.
