Spark Advance PID's

The diagnostic tool will display the SPARKADDER PID when in the AFCM mode and the SPARKADV PID
when in the PCM mode. The SPARKADDER PID shown in the AFCM mode is the amount of spark advance
the compuvalve is requesting be added to the base vehicle spark advance. The SPARKADV PID shown in the
PCM mode is actual spark timing (including SPARKADDER) being sent to the engine.

INTRODUCTION

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 chart.

PIN VOLTAGE/PID VALUES charts 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
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.

TEST EQUIPMENT

In order to read Parameter Identification (PID) values, a New Generation Star (007-00500 ) scan tool,
Worldwide Diagnostic System (WDS) or other OBD-II compliant scan tool is required. A DVOM, 104-pin
Breakout Box and appropriate adapter cable are used to check PCM pin values. If a breakout box is not
available, PCM pin values can be checked by backprobing PCM connector.

TEST PROCEDURES

PIN VOLTAGE TESTING

Access PCM connector. See POWERTRAIN CONTROL MODULE LOCATIONS . If a breakout box is
available, disconnect negative battery terminal. Connect breakout box to PCM harness connector and PCM.
Reconnect negative battery cable. Take desired measurements between ground pin and specified pin on

NOTE:

For information pertaining to the gasoline portion, see PIN VOLTAGE CHARTS -
CUTAWAY, ECONOLINE, F450 SUPER DUTY, F550 SUPER DUTY, PICKUP & RV
CUTAWAY - GASOLINE & CNG article.

CAUTION: When battery is disconnected, vehicle computer and memory systems

may lose memory data. Driveability problems may exist until computer
systems have completed a relearn cycle. See COMPUTER RELEARN
PROCEDURES article in GENERAL INFORMATION before disconnecting
battery.
