3	Repair as necessary. Did you complete the repair?	System OK	--
4	Disconnect the actuator at the door. Inspect the range of the door travel and the effort required to move it. Does the door move freely through its entire range of travel so that it can close at both ends of the range?	Go to Step 5	Go to Step 3
5	Inspect the travel of the actuator by turning the control knob with the engine running. Is the actuator travel OK?	Go to Step 6	Go to Step 7
6	Reinstall the actuator. Recheck the system using the Control Settings/Correct Results tests in this procedure. Does the system perform properly?	System OK	Go to Step 9
