WHAT IS OBD?
Craftsman 14063 1
WHAT IS OBD?
The Code Reader 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 cars and light trucks 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 Code Reader, is required to retrieve these codes, which
consumers and professionals use as a starting point for repairs.
The Code Reader provides the additional ability to retrieve Anti-Lock
Brake System (ABS) DTCs from most Chrysler/Jeep, Ford/Mazda,
GM/Isuzu, Honda/Acura and Toyota/Lexus vehicles. Refer to Vehicle
Applications - ABS on page 32 for vehicles covered.

Safety Precautions
SAFETY FIRST
Craftsman 14063 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 trouble-shooting, 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 Code Reader to or disconnecting the Code
Reader 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.
The vehicle's battery produces highly flammable hydrogen
gas. To prevent an explosion, keep all sparks, heated items
and open flames away from the battery.
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.

The Code Reader is designed to work on all OBD 2 compliant vehicles.
All 1996 and newer vehicles (cars and light trucks) sold in the United
States are OBD 2 compliant. This includes all Domestic, Asian and
European vehicles.
Some 1994 and 1995 vehicles are OBD 2 compliant. To find out if a
1994 or 1995 vehicle is OBD 2 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 OBD 2 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.

COMPUTER ENGINE CONTROLS
The Introduction of Electronic Engine Controls
As a result of increased air pollution (smog) in large cities,
such as Los Angeles, the California Air Resources Board
(CARB) and the Environmental Protection Agency (EPA)
set new regulations and air pollution standards to deal with
the problem. To further complicate matters, the energy crisis of
the early 1970s caused a sharp increase in fuel prices over a
short period. As a result, vehicle manufacturers were not only
required to comply with the new emissions standards, they also
had to make their vehicles more fuel-efficient. Most vehicles
were required to meet a miles-per-gallon (MPG) standard set by the U.S.
Federal Government.
Precise fuel delivery and spark timing are needed to reduce vehicle
emissions. Mechanical engine controls in use at the time (such as
ignition points, mechanical spark advance and the carburetor)
responded too slowly to driving conditions to properly control fuel
delivery and spark timing. This made it difficult for vehicle manufacturers
to meet the new standards.
A new Engine Control System had to be designed and integrated with
the engine controls to meet the stricter standards. The new system had
to:
Respond instantly to supply the proper mixture of air and fuel for any
driving condition (idle, cruising, low-speed driving, high-speed
driving, etc.).
Calculate instantly the best time to “ignite” the air/fuel mixture for
maximum engine efficiency.
Perform both these tasks without affecting vehicle performance or
fuel economy.
Vehicle Computer Control Systems can perform millions of calculations
each second. This makes them an ideal substitute for the slower
mechanical engine controls. By switching from mechanical to electronic
engine controls, vehicle manufacturers are able to control fuel delivery
and spark timing more precisely. Some newer Computer Control
Systems also provide control over other vehicle functions, such as
transmission, brakes, charging, body, and suspension systems.
Electronic Computer C
o
ntrol Systems make it possible
for vehicle manufacturers to comply with the tougher
emissions and fuel efficiency standards mandated by
State and Federal Governments.
Onboard Diagnostics
COMPUTER ENGINE CONTROLS
Craftsman 14063 9
,
The Basic Engine Computer Control System
The on-board computer is the heart of the Computer
Control System. The computer contains several programs
with preset reference values for air/fuel ratio, spark or
ignition timing, injector pulse width, engine speed, etc.
Separate values are provided for various driving conditions,
such as idle, low speed driving, high-speed driving, low load,
or high load. The preset reference values represent the ideal
air/fuel mixture, spark timing, transmission gear selection,
etc., for any driving condition. These values are programmed
by the vehicle manufacturer, and are specific to each vehicle model.
Most on-board computers are located inside the vehicle behind the dashboard,
under the passenger’s or driver’s seat, or behind the right kick panel. However,
some manufacturers may still position it in the engine compartment.
Vehicle sensors, switches, and actuators are located throughout the
engine, and are connected by electrical wiring to the on-board computer.
These devices include oxygen sensors, coolant temperature sensors,
throttle position sensors, fuel injectors, etc. Sensors and switches are
input devices. They provide signals representing current engine
operating conditions to the computer. Actuators are output devices. They
perform actions in response to commands received from the computer.
The on-board computer receives information inputs from sensors and
switches located throughout the engine. These devices monitor critical
engine conditions such as coolant temperature, engine speed, engine
load, throttle position, air/fuel ratio etc.
The computer compares the values received from these sensors with its
preset reference values, and makes corrective actions as needed so
that the sensor values always match the preset reference values for the
current driving condition. The computer makes adjustments by
commanding other devices such as the fuel injectors, idle air control,
EGR valve or Ignition Module to perform these actions.
The Computer Control System consists of an on-board
computer and several related control devices (sensors,
switches, and actuators).
