Introduction
WHAT IS OBD?
3100j 1
WHAT IS OBD?
The diagnostic tool is designed to work on all OBD2 compliant
vehicles. All 1996 and newer vehicles (cars, light trucks and SUVs)
sold in the United States are OBD2 compliant.
One of the most exciting improvements in the
automobile industry was the addition of on-
board diagnostics (OBD) on vehicles, or in more
basic terms, the computer that activates the
vehicle’s “CHECK ENGINE” light. OBD1 was
designed to monitor manufacturer-specific
systems on vehicles built from 1981 to 1995.
Then came the development of OBD2, which is
on all 1996 and newer vehicles sold in the U.S. Like its predecessor,
OBD2 was adopted as part of a government mandate to lower vehicle
emissions. But what makes OBD2 unique is its universal application for
all late model cars and trucks - domestic and import. This sophisticated
program in the vehicle’s main computer system is designed to detect
failures in a range of systems, and can be accessed through a universal
OBD2 port, which is usually found under the dashboard. For all OBD
systems, if a problem is found, the computer turns on the “CHECK
ENGINE” light to warn the driver, and sets a Diagnostic Trouble Code
(DTC) to identify where the problem occurred. A special diagnostic tool,
such as the diagnostic tool, is required to retrieve these codes, which
consumers and professionals use as a starting point for repairs.
The diagnostic tool provides the additional ability to retrieve enhanced
DTCs from most Chrysler/Jeep, Ford/Mazda, GM/Isuzu, Honda/Acura
and Toyota/Lexus vehicles, as well as Anti-Lock Brake System (ABS)
DTCs, Supplemental Restraint System (SRS) DTCs and vehicle
information. The types of enhanced data available depends on the
vehicle make.
To learn more about vehicle Computer Control Systems and
OBD2, see COMPUTER ENGINE CONTROLS on page 15.

Safety Precautions
SAFETY FIRST!
3100j 3
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.
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 diagnostic tool to or disconnecting
the diagnostic tool from the vehicle’s Data Link Connector
(DLC).
To avoid personal injury, instrument damage and/or
damage to your vehicle; do not use the diagnostic tool
before reading this manual.

Safety Precautions
SAFETY FIRST!
4 3100j
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.

VEHICLES COVERED
The diagnostic tool is designed to work on all OBD2 compliant vehicles.
All 1996 and newer vehicles (cars and light trucks) sold in the United
States are OBD2 compliant.
Federal law requires that all 1996 and newer cars and light
trucks sold in the United States must be OBD2 compliant; this
includes all Domestic, Asian and European vehicles.
Some 1994 and 1995 vehicles are OBD2 compliant. To find out if a
1994 or 1995 vehicle is OBD2 compliant, check the following:
1. The Vehicle Emissions Control Information (VECI) Label. This
label is located under the hood or by the radiator of most vehicles. If
the vehicle is OBD2 compliant, the label will state “OBD II
Certified.”
2. Government Regulations require that all
OBD2 compliant vehicles must have a
“common” sixteen-pin Data Link
Connector (DLC).
Some 1994 and 1995 vehicles have 16-pin connectors but are
not OBD2 compliant. Only those vehicles with a Vehicle
Emissions Control Label stating “OBD II Certified” are OBD2
compliant.
Data Link Connector (DLC) Location
The 16-pin DLC is usually
located under the instrument
panel (dash), within 12 inches
(300 mm) of center of the panel,
on the driver’s side of most
vehicles. It should be easily
accessible and visible from a
kneeling position outside the
vehicle with the door open.

On some Asian and European vehicles the DLC is located
behind the “ashtray” (the ashtray must be removed to access it)
or on the far left corner of the dash. If the DLC cannot be
located, consult the vehicle’s service manual for the location.
BATTERY REPLACEMENT
Replace batteries when the battery symbol is visible on display
and/or the 3 LEDS are all lit and no other data is visible on screen.
1. Locate the battery cover on the back of the diagnostic tool.
2. Using a Phillips head screwdriver, remove the screw from the
battery cover.
3. Slide the battery cover off (use your fingers).
4. Replace batteries with three AA-size batteries (for longer life, use
Alkaline-type batteries).
5. Reinstall the battery cover and screw on the back of the diagnostic
tool.
Adjustments After Battery Installation
The first time the unit is turned on, you must select the desired display
language (English, French or Spanish) and unit of measurement (USA
or Metric) as follows:
1. Press the POWER/LINK button
to turn the diagnostic tool “ON.”
The Select Language screen
displays.
2. Use the UP and DOWN
buttons, as necessary, to highlight the
desired display language.
3. When the desired display language is
selected, press the ENTER button
to confirm your selection.
The Select Unit screen displays.
4. Use the UP and DOWN
buttons, as necessary, to highlight the
desired unit of measurement.
5. When the desired unit of measurement is selected, press the
ENTER button to confirm your selection.
After the initial language and unit of measurement selections
are performed, these, as well as other settings, can be
changed as desired. Proceed to “ADJUSTMENTS AND
SETTINGS” on page 85 for further instructions.
