Using Output State Control and Accessing PIDs
WARNING: This page is about a different car, the 2009 Mercury Milan and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
To confirm that the output state control value was sent by the scan tool and the PCM has accepted the output state control substitution, a corresponding PID for each output state control parameter must be monitored. Additional PIDs should be monitored to help the technician adequately diagnose the transmission.
