NGS-Introduction 1-3

LESSON 1

NOTES GENERIC OBD II FUNCTIONS

The EPA OBD II requires that certain emission components be
monitored continuously so that malfunctions can be corrected
as soon as they occur. The NGS is designed to access these
codes.

OBD II also requires that all vehicles use the same codes for
these concerns.

Therefore, NGS will be able to access emission system
diagnostic trouble codes (DTCs) for any vehicle that complies
with OBD II.

NGS/OBD II functions also include a number of tests and
functions, these are detailed in the OBD II lesson of this
manual.

VIEW RECORDER AREAS

Many of the NGS functions allow you to record the parameter
identification numbers (PlDs) or DTCs for review at a later
time. In the case of PlDs, the data can be viewed on the NGS
screen in either graph or table form. Any data results can be
printed as well as viewed on the screen.

DIAGNOSTIC TROUBLE CODE LIBRARY

To aid you in diagnosing concerns, the NGS has a built-in
library of trouble codes and their meanings. The DTC library
can be accessed under the menu for each type of test (PCM,
ABS, etc.)

REPROGRAMMING THE EEC-V PCM

The NGS can be used to reprogram the EEC-V PCM. A Flash
Kit consisting of a data transfer card and a special cable is
required. Consult your NGS user guide for detailed information.

MENU TREE

The chart on page 3-3 shows the current menus and tests
available to the user of the New Generation Star tester .

These menus fall into three categories:

SET-UP MENUS

This menu allows the user to adjust certain NGS parameters,
e.g. LCD contrast.

VEHICLE SPECIFIC MENUS

These menus run tests on specified vehicles. They require that
a vehicle and an engine be selected before proceeding.

TOOL FUNCTION MENUS

These menus are for using the NGS as a generic diagnostic
tool. They can be used without specifically identifying the
vehicle being worked on. However , if a vehicle is selected PIDs
can be monitored while using tool functions.

GRAPHING PIDS

The graphing capability of NGS allows you to make visual
comparisons between closely related PlDs, to determine
whether or not their interaction is correct. It also allows you to
see a “glitch” that is not obvious on the table format.

Just as with the table display , up to four PlDs can be selected
for graphing, but only two at a time can be displayed. When the
graph display appears on screen, the names of the two
currently selected PlDs will appear - one on the right and one
on the left . If more than two PlDs have been selected for
viewing, you can change what is displayed on screen by using
the numeric keypad.

To change the left-hand PID, push number 2 on the numeric
keypad.

To change the right-hand PID, push the number 9 on the

be selected.

The diagnostic trouble code library is accessed by selecting
diagnostic data link from the main menu.

1. Select the system (PCM, ABS, etc.)

2. Select DIAGNOSTIC TROUBLE CODE LIBRARY.

3. The screen that appears shows the following:

4. The selected vehicle (94 3.8L AUTO MUST ANG in the
example)

5. The selected diagnostic trouble code (DTC) - (P0100 in the
example). Use the scroll bar to change the DTC.

6. The selected group (powertrain, chassis, etc.) ­(POWERTRAIN in the example). Use the numeric keypad keys
to switch groups.

In this example:
P = powertrain
C = chassis
B = body
U = network
To find the definition of a code you are familiar with, or which

came up during a test, push the numeric keypad number that
corresponds to FIND. In this example, it is number 7.

LESSON 6

NOTES

GENERIC OBD II - ON-BOARD DIAGNOSTICS

A major reason for the development of the New Generation
Star (NGS) tester was to meet the requirements of the new
EP A OBD II requirements for continuous monitoring of
emissions and related systems. Among other requirements,
OBD II calls for standardized emission codes and a
standardized means of accessing them. NGS meets these
requirements.

The Ford NGS program card covers a wide range of tests that
may need to be completed as part of proper emissions control.
The generic OBD II functions are more limited because they
are designed to apply to all vehicles by all manufacturers. In
general, use the generic OBD II functions only if you need
freeze frame data or if you are diagnosing emissions concerns
on a non-Ford vehicle.

SELECTING AN OBD II EEC-V VEHICLE

The generic OBD II functions module is designed so that you
do not have to select a vehicle prior to utilization.

When NGS is connected to an EEC-V vehicle and powered
up, it begins to search for the appropriate link to determine
whether it is connected to an EEC-V, or other OBD II vehicle.
If the link is found, NGS allows you to proceed into the generic
OBD II functions module. If the link is not found, NGS displays
an error screen, explaining to you the possible causes for not
finding the link. Upon linking to the EEC-V system, NGS begins
to communicate with the vehicles’ processors to determine
which PlDs are available and which PlDs are not available.

LESSON 6

NOTES

Freeze frame is a “snapshot” of operation conditions at the
time a MIL illuminating DTC occurs.

Freeze frame information is certain parameter identification
data (PID) at the time of the DTC. The data appearing in these
critical PlDs is locked into the freeze frame data memory
location.

The critical PlDs, their acronyms, descriptions and units of
measure are shown in the chart.

Freeze frame data is reached from the generic OBD II
functions menu.

Freeze frame data appearing on the NGS screen is for the
first detected emission related concern. That means that if
more than one emission related concern is encountered, the
first one detected will have freeze frame data available.

The exceptions to this are the DTCs for adaptive fuel at limit
(P1 130 and P1150) and the misfire DTCs(P0300 through
P0308). These eleven DTCs have priority access to the
freeze frame storage area.

For example, the PCM detects a misfire or adaptive fuel
concern after another MIL level DTC has placed data in the
freeze frame memory location. The data for the misfire or
adaptive fuel concern always overwrites the data for the lower
priority DTC.

The freeze frame memory location is then locked to prevent
overwriting of the misfire or adaptive fuel information.
