Using Output State Control (OSC) and Monitoring PIDs: Notes
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
To confirm that the OSC value was sent by the NGS or WDS and the PCM has accepted the OSC command, a corresponding PID for each OSC parameter must be monitored. After sending the OSC value, the corresponding PID value should be the same as the OSC value. Additional PIDs should be monitored to help the technician accurately diagnose the transmission. The following is a list of PIDs to monitor while using OSC.
