Output State Check
WARNING: This page is about a different car, the 1987 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The Output State Check is used as an aid in servicing output actuators associated with the EEC-IV system. It allows you to energize and de-energize most of the system output actuators on and off on command.
This mode is entered after all codes have been received from KEY ON/ENGINE OFF (KOEO) and CONTINUOUS SELF-TEST. At this time, leave SELF-TEST activated and depress throttle. Each time throttle is depressed, the output actuators will change state (go from on to off, or off to on).
