KOEO OUTPUT STATE SELF-TEST is a functional test of PCM performed on demand with ignition on and engine off. This test is designed to cycle outputs high and low. After pressing "Trigger" to start test, you must then press and release accelerator pedal to cycle outputs high: solenoids, WAIT TO START indicator, Injector Driver Module (IDM) relay, Transmission Control Indicator Light (TCIL), Fuel Delivery Control Signal (FDCS), Cylinder Identification (CID) and IDM Electronic Feedback (EF). The second time accelerator pedal is pressed and released, outputs are cycled low, with exception to glow plug relay which is cycled on for 5 seconds when accelerator is pressed and released the first time only. This self-test does not set DTCs.
