Output State Check
WARNING: This page is about a different car, the 1993 Mazda Navajo. However, it is still accessible from the selected car via links, so may be relevant.
Check is used as an aid in servicing output actuators associated with EEC-IV system. It allows technicians to energize and de-energize most system output actuators on command. This mode is entered from KOEO SELF-TEST after all codes have been retrieved. With self-test activated, depress throttle to initiate test sequence. Each time throttle is depressed and released, output actuators will change state (from on to off or off to on).
