Parameter Identification (PID) Access: Description
WARNING: This page is about a different car, the 2004 Ford Pickup Heritage. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Always access PCM PIDs before AFCM PIDs.
The parameter identification (PID) mode allows access to certain data values, analog and digital inputs and outputs, calculated values and system status information. Throughout the service information articles there will be references to these PID values.
