WARNING: This page is about a different car, the 2002 Ford Pickup and 2002 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The purpose is to verify how compuvalve and actuator circuit respond to a sensor input. Access AFCM, select, monitor and record appropriate sensor PID(s). Create a condition to cause an input condition to change and observe PID or actuator signal circuit change, with use of a scan tool.
