Parameter Identification (PID)

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 manual, 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.

Accessing Generic OBD II PIDs:

New Generation STAR (NGS) Tester
1. Perform safety precautions.
2. Connect New Generation STAR (NGS) to On-Board Diagnostics II (OBD II) Data Link Connector (DLC).
3. Turn key ON or start vehicle.
4. Select VEHICLE & ENGINE SELECTION menu (OPTIONAL).
5. Select NEW VEHICLE YEAR & MODEL (OPTIONAL).
6. Select year, engine, model with the appropriate qualifier, if needed (i.e., transmission, 49 state, California) (OPTIONAL).
7. Select GENERIC OBD II FUNCTIONS.
- Press CONT button if all OBD II monitors are not complete.
8. Select PID/DATA MONITOR.
9. Select the PIDs, press TRIGGER.
10. Select START to begin.







Generic OBD II PID List
X = Freeze Frame PID (refer to Freeze Frame Access for more information)
*OL = Open loop, have not satisfied conditions for closed loop.
CL = Closed loop using HO2S(s) as feedback for fuel control.
OL Drive = Open loop due to driving conditions (heavy accel).
OL Fault = Open loop due to vehicle system fault.
CL Fault = Closed loop fuel control, but fault with HO2 Sensor(s).
