Parameter Identification (PID) Description

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 Diagnostic Procedures, there will be references to PID values. Some of the PID references are from a generic OBD II PID list all scan tools must access. If a Ford PID is referenced and is not on this list, it can be accessed from the New Generation STAR (NGS) tester scan tool (or equivalent) through the Diagnostic Data Link Menu. If a Generic Scan Tool (GST) is used for non-generic OBD II PIDs, a string of characters may have to be entered.
