Section 85 (Engine Controls - Pin Voltage Charts): Introduction

WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2002 Mercury Villager, 2002 Mercury Mountaineer, 2002 Lincoln Navigator, 2002 Lincoln Blackwood, and 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

Parameter Identification (PID) mode allows access to certain data values, analog and digital inputs and outputs, calculated values, and system status information. There are 2 types of PID lists available. The first is a Ford specific PID list that can be accessed by using New Generation Star (NGS) scan tool or Worldwide Diagnostic System (WDS). The second is a Generic OBD-II PID list. This is a standard set of PIDs that all manufacturer's scan tools can access. Generic PIDs are located at the end of each PIN VOLTAGE/PID VALUES table.

PIN VOLTAGE/PID VALUES tables are used for diagnosing intermittent symptoms and faults that are unable to be resolved during self-diagnostics. Pin tests ensure the Powertrain Control Module (PCM) is receiving and transmitting proper voltage and other signals. If diagnosing a symptom, see appropriate symptom in REFERENCE VALUE SYMPTOM table under SYMPTOM TESTING under TEST PROCEDURES.

PID values are continuously updated when accessing PIDs from a specific PID list. Before performing tests, ensure mechanical conditions have been inspected and self-diagnostics has been attempted. Technical Service Bulletins (TSBs) may also be helpful in correcting a hard to diagnose problem.
