Output State Check
WARNING: This page is about a different car, the 1994 Mazda Navajo. However, it is still accessible from the selected car via links, so may be relevant.
Output state check is used as an aid for servicing EEC-IV system output actuators. It allows technicians to operate most output actuators on command. This mode is entered from KOEO SELF-TEST after all codes have been retrieved. Leave SELF-TEST activated, and depress throttle to initiate test sequence. Each time throttle is depressed and released, output actuators will change from on to off or off to on.
