Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Output State Check
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 KOEO and CONTINUOUS SELF-TEST. At this time, leave SELF-TEST activated and depress throttle. Each time throttle is depressed and released, the output actuators will change state (go from on to off, or off to on).
