Parameter Identification (PID): Description
WARNING: This page is about a different car, the 1997 Ford Aspire. However, it is still accessible from the selected car via links, so may be relevant.
The Parameter Identification (PID) mode allows the technician to view data values (PCM inputs and outputs) in real time. Generic PIDs are common to all vehicles and any OBD-II scan tool can access them. Ford Specific (non-generic) PIDs can be accessed using New Generation Star (NGS) scan tool.
