Safety Precautions
SAFETY FIRST!
SAFETY FIRST!
This manual describes common test procedures used by experienced
service technicians. Many test procedures require precautions to avoid
accidents that can result in personal injury, and/or damage to your
vehicle or test equipment. Always read your vehicle's service manual
and follow its safety precautions before and during any test or service
procedure. ALWAYS observe the following general safety precautions:
When an engine is running, it produces carbon monoxide,
a toxic and poisonous gas. To prevent serious injury or
death from carbon monoxide poisoning, operate the vehicle
ONLY in a well-ventilated area.
To protect your eyes from propelled objects as well as hot
or caustic liquids, always wear approved safety eye
protection.
When an engine is running, many parts (such as the
coolant fan, pulleys, fan belt etc.) turn at high speed. To
avoid serious injury, always be aware of moving parts.
Keep a safe distance from these parts as well as other
potentially moving objects.
Engine parts become very hot when the engine is running.
To prevent severe burns, avoid contact with hot engine parts.
P RND L
Before starting an engine for testing or troubleshooting,
make sure the parking brake is engaged. Put the
transmission in park (for automatic transmission) or
neutral (for manual transmission). Block the drive wheels
with suitable blocks.
Connecting or disconnecting test equipment when the
ignition is ON can damage test equipment and the vehicle's
electronic components. Turn the ignition OFF before
connecting the Scan Tool to or disconnecting the Scan
Tool from the vehicle’s Data Link Connector (DLC).
To prevent damage to the on-board computer when taking
vehicle electrical measurements, always use a digital
multimeter with at least 10 megOhms of impedance.
Fuel and battery vapors are highly flammable. To prevent
an explosion, keep all sparks, heated items and open
flames away from the battery and fuel / fuel vapors. DO
NOT SMOKE NEAR THE VEHICLE DURING TESTING.
Don't wear loose clothing or jewelry when working on an
engine. Loose clothing can become caught in the fan,
pulleys, belts, etc. Jewelry is highly conductive, and can
cause a severe burn if it makes contact between a power
source and ground.

CODE RETRIEVAL PROCEDURE
Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
Never replace a part based only on the DTC definition.
Each DTC has a set of testing procedures, instructions and
flow charts that must be followed to confirm the location of
the problem. Always refer to the vehicle's service manual
for detailed testing instructions.
Check your vehicle thoroughly before performing
any test.
ALWAYS observe safety precautions whenever working on a
vehicle.
1. Turn the ignition off.

12. Read and interpret Diagnostic Trouble Codes/system condition
using the display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the display) as
visual aids to make it easier to determine engine system
conditions.
„
Green LED – Indicates that all engine
systems are “OK” and operating
normally. All monitors supported by
the vehicle have run and performed
their diagnostic testing, and no trouble
codes are present. All Monitor icons
will be solid.
„
Yellow LED – Indicates one of the
following conditions:
A. A PENDING CODE IS PRESENT – If
the yellow LED is illuminated, it may
indicate a Pending code is present.
Check the display for confirmation. A
Pending code is confirmed by the
presence of a numeric code and the
word PENDING.
B. MONITOR NOT RUN STATUS – If
the display shows a zero (indicating
there are no DTC’s present in the
vehicle’s computer memory), but the
yellow LED is illuminated, it may be
an indication that some of the
Monitors supported by the vehicle
have not yet run and completed their
diagnostic testing. Check the display
for confirmation. All Monitor icons that
are blinking have not yet run and
completed their diagnostic testing; all
Monitor icons that are solid have run
and completed their diagnostic testing.
10
Using the Scan Tool
CODE RETRIEVAL PROCEDURE
„
Red LED – Indicates there is a
problem with one or more of the
vehicle’s systems. The red LED is
also used to indicate that DTC(s)
are present. In this case, the
Malfunction Indicator (Check Engine)
lamp on the vehicle’s instrument
panel will be illuminated.
„
DTC’s that start with “P0”, “P2” and
some “P3” are considered Generic
(Universal). All Generic DTC definitions are the same on all OBD2
equipped vehicles. The Scan Tool automatically displays the code
definitions (if available) for Generic DTC’s.
„
DTC’s that start with “P1” and some “P3” are Manufacturer specific
codes and their code definitions vary with each vehicle manufacturer.
13. If more than one DTC was retrieved, and to view Freeze Frame
Data, press and release DTC/FF as necessary.
Each time DTC/FF is pressed and released, the Scan Tool will
scroll and display the next DTC in sequence until all DTCs in its
memory have displayed.
„ Freeze Frame Data (if available) will display after DTC #1.
„ In
OBD2 systems, when an
emissions-related engine malfunction
occurs that causes a DTC to set, a
record or snapshot of engine conditions at the time that the malfunction
occurred is also saved in the vehicle’s
computer memory. The record saved
is called Freeze Frame data. Saved
engine conditions include, but are not
limited to: engine speed, open or closed loop operation, fuel system
commands, coolant temperature, calculated load value, fuel
pressure, vehicle speed, air flow rate, and intake manifold pressure.
If more than one malfunction is present that causes more than
one DTC to be set, only the code with the highest priority will
contain Freeze Frame data. The code designated “01” on the
Scan Tool display is referred to as the PRIORITY code, and
Freeze Frame data always refers to this code. The priority
code is also the one that has commanded the MIL on.
14. When the last retrieved DTC has been displayed and DTC/FF is
pressed, the Scan Tool returns to the “Priority” Code.
15. Determine engine system(s) condition by viewing the Scan Tool’s
display for any retrieved Diagnostic Trouble Codes, code definitions and
Freeze Frame data, interpreting the green, yellow and red LEDs.
„ If DTC’s were retrieved and you are going to perform the repairs
yourself, proceed by consulting the Vehicle’s Service Repair
Manual for testing instructions, testing procedures, and flow
charts related to retrieved code(s).

CODE RETRIEVAL PROCEDURE
Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
Never replace a part based only on
the DTC definition. Each DTC has a set of testing
procedures, instructions and flow charts that must be
followed to confirm the location of the problem. Always
refer to the vehicle’s service manual for detailed testing
instructions.
Check your vehicle thoroughly before performing
any test.
ALWAYS observe safety precautions whenever working on a
vehicle.
1. Locate the vehicle’s Data Link Connector (DLC).

CODE RETRIEVAL PROCEDURES
Overview of Ford Code Retrieval Process
Ford's computer self-diagnostic system is
divided into four main sections:
1. "Key On Engine Off" (KOEO) Self-Test
2. "Continuous Memory" (CM) Self-Test
3. "Key On Engine Running" (KOER) SelfTest
4. Other EEC-IV System tests
These Self-Tests are specially designed to monitor and/or test the
various components and circuits that are controlled by the vehicle's
computer, and to save and/or transmit diagnostic test results to the
Scan Tool in the form of numerical fault codes.
The "Continuous Memory" Self-Test is designed to run continuously
whenever the vehicle is normal operation. If a fault is detected by the
"Continuous Memory" Self-Test, a fault code is saved in the vehicle's
computer memory for later retrieval.
Ford’s On-Board Diagnostic Self-Tests are designed in such a way that
in order to properly diagnose a problem, you must perform all the SelfTests, in the proper sequence.
As described previously, some tests are designed to detect problems
only when the vehicle is in normal operation. Some tests are designed
to activate components and detect problems only with the Key On and
Engine Off. Other tests are designed to activate components and test
their operation only with the Key On and Engine Running. Do not take
short cuts. If you fail to perform a test, or you perform a test out of
sequence, you might miss a problem that is only detected during that
part of the test.
Key On Engine Off (KOEO) Test
During the KOEO Self-Test, two groups of codes are retrieved
„
28
The first group of codes are called "KOEO codes". A "KOEO" icon
shows to indicate the code is a "KOEO" code.

Tool is re-linked to a vehicle to retrieve codes, any prior codes in its
memory are automatically cleared.
10. Follow the testing and repair procedures outlined in the vehicle's service
repair manual to correct DTCs. Codes should be addressed and
eliminated in the order they were received, erasing and retesting after
each repair is made to be sure the fault was eliminated. Code 12 will
appear alone when no other fault codes are present.
„ It may be necessary to test drive the vehicle to reset fault codes
13, 15, 24, 44, 45, and 55 after they have been erased.
Whenever codes 51, 52, 54, or 55 are displayed with other

Live Data Mode
VIEWING LIVE DATA
The Scan Tool lets you view "real-time" Live Data. This information
includes values (volts, rpm, temperature, speed etc.) and system status
information (open loop, closed loop, fuel system status, etc.) generated by
the various vehicle sensors, switches and actuators. These are the same
signal values generated by the sensors, actuators, switches and/or
vehicle system status information used by the vehicle's computer when
calculating and conducting system adjustments and corrections.
The real time (Live Data) vehicle operating information (values/status)
that the computer supplies to the Scan Tool for each sensor, actuator,
switch, etc. is called Parameter Identification (PID) Data.
Each PID (sensor, actuator switch, status, etc.) has a set of operating
characteristics and features (parameters) that serve to identify it. The
Scan Tool displays this information for each sensor, actuator, switch or
status that is supported by the vehicle under test.
WARNING: If the vehicle must be driven in order to perform a
troubleshooting procedure, ALWAYS have a second person
help you. One person should drive the vehicle while the other
person observes the Scan Tool data. Trying to drive and
operate the Scan Tool at the same time is dangerous, and
could cause a serious traffic accident.
