Important Safety Information
Work Area Safety
1� Keep your work area clean and well lit�
Cluttered benches and dark
areas may cause accidents�
2� Do not connect or disconnect the
Code Reader while the ignition
is on or the engine is running�
3� DO NOT attempt to operate
the Code Reader while driving
the vehicle. Have a passenger
operate the Code Reader.
4� Before testing a vehicle, engage the
parking brake and chock the tires�
5� NEVER smoke or allow a spark or
flame in vicinity of battery or engine�
6� Carbon Monoxide is produced
while the vehicle’s engine is
operating and is deadly in a closed
environment. Early signs of carbon
monoxide poisoning resemble the flu,
with headaches, dizziness, or nausea�
If you have these signs, the work
area may not be vented properly� Get
fresh air immediately� Operate the
vehicle in a well-ventilated work area�
7� Do not operate the Code Reader
in explosive atmospheres, such
as in the presence of flammable
liquids, gases, or heavy dust�
8� Keep a fire extinguisher suitable for
gasoline/chemical/electrical fires nearby�
9� Use extreme caution when working
around the ignition coil, distributor
cap, ignition wires and spark plugs�
These components create hazardous
voltages when the engine is running�
10� Keep bystanders, children and visitors
away while operating the Code Reader�
11� This product is not a toy� Do not allow
children to play with or near this item�
12� Use as intended only�
13� Inspect before every use; do not use
if parts are loose or damaged�
14� Do not place the Code Reader
on any unstable surface�
15� Handle the Code Reader with care� If
the Code Reader is dropped, check
for breakage and any other conditions
that may affect its operation�
16� Keep the Scan Tool dry, clean,
free from oil, water or grease�
Use a mild detergent on a clean
cloth to clean the outside of the
Scan Tool, when necessary�
17� Store the Code Reader and
accessories in a locked area
out of the reach of children�
18� Maintain product labels and
nameplates� These carry
important safety information�
If unreadable or missing, contact
Harbor Freight Tools for a replacement�
Electrical Safety
1� Do not use the Code Reader
while standing in water�
2� Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators�
3� Do not expose the Code Reader to rain
or wet conditions�
Water entering the Code Reader
increases the risk of electric shock.
Page 4 For technical questions, please call 1-888-866-5797. Item 64981
4� Make sure your hands are dry before
operating the Code Reader�
Personal Safety
1� Wear ANSI-approved safety

tired or under the influence of
drugs, alcohol, or medications� A
moment of interruption can result
in serious personal injury�
4� People with pacemakers should
consult their physician(s) before
use� Electromagnetic fields in close
proximity to heart pacemaker could
cause pacemaker interference
or pacemaker failure�
5� The warnings, precautions, and
instructions discussed in this instruction
manual cannot cover all possible
conditions and situations that may
occur� It must be understood by the
operator that common sense and
caution are factors which cannot
be built into this product, but must

Overview
OBD II On-Board Diagnostics
It is required by the EPA that all 1996 and
newer vehicles sold in the United States be
equipped with an OBD II computer system�
OBD II is an early warning system
designed to monitor engine, transmission,
and emissions control components by
performing specific diagnostic tests�
When a fault condition is detected, the
system captures important data and
activates the “Check Engine” light�
If the light comes on, the vehicle might have
a condition that wastes fuel, shortens engine
life, or causes excessive air pollution� If
the problem that caused the light to come
on is addressed, for instance a loose gas
cap is tightened, the light will go out�
If the light comes on and stays on, a minor
engine fault condition is occurring and
should be addressed as soon as possible
If the light is blinking, a severe engine
fault condition is occurring and should
be addressed immediately�
The Code Reader connects to the vehicle’s
computer system and captures information
that can help identify the fault condition�
Vehicle Coverage
This Code Reader is designed to work with
all OBD II compliant vehicles, including
those equipped with a CAN bus�
OBD II was installed in some 1994 and
1995 model year gasoline vehicles�
To verify if a 1994 or 1995 vehicle is
OBD II compliant, check the Vehicle
Emissions Control Information label, which
is located in the engine compartment�

Diagnostic Trouble Code
A DTC is a five digit alphanumeric identifier for a fault condition identified
by the OBD II system� There are three types of DTCs:
1� Pending - When a fault condition
is identified during a Drive Cycle,
but does not meet enough
criteria to activate the MIL�
If the fault condition occurs during two
consecutive Drive Cycles, it will turn into
a Stored DTC and the MIL will activate�
2� Stored - A DTC is stored when a fault
condition has occurred that meets
enough criteria to activate the MIL�
3� Permanent - A stored DTC that can only
be cleared by the OBD II system, after
repairs are made, and a set number of
Driving Cycles have been completed�
