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 (GET) 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 NGS to OBD II Data Link Connector (DLC).
3. Select VEHICLE & ENGINE SELECTION menu (OPTIONAL).
4. Select NEW VEHICLE YEAR & MODEL (OPTIONAL).
5. Select year, engine, model with the appropriate qualifier, if needed (i.e., transmission, 49 state, California) (OPTIONAL).
6. Select GENERIC OBD II FUNCTIONS.
7. If all OBD II monitors are NOT complete, press CONT button.
8. Select PID/DATA MONITOR.
9. Turn key ON or start vehicle.
10. Select the PIDs, press TRIGGER.
11. Select START to begin.

NOTES
X = Freeze Frame PID (refer to Freeze Frame Data Access for more information)
OL = Open loop, have not satisfied conditions for closed loop.
CL = Closed loop using oxygen sensor(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 oxygen sensor(s).
