For your safety, read this manual thoroughly before operating your
Scan Tool. Always refer to and follow safety messages and test
procedures provided by the manufacturer of the vehicle or eq uipment
being tested.
The safety messages presented below and throughout this user’s
manual are reminders to the operator to exercise extreme care when
using this test instrument.
Read All Instructions
Read, understand and follow all safety messages and instructions in
this manual and on the test equipment. Safety messages in this section
of the manual contain a signal wor d with a three-p art message and, in
some instances, an icon.
Safety Messages
Safety messages are provided to help prevent personal injury and
equipment damage. All safety messages are introduced by a signal
word. The signal word indicates the level of the hazard in a situation.
The types of safety messages are.
Indicates a possible hazardous situation which, if not
avoided, will result in death or serious injury to
operator or bystanders.
Indicates a possible hazardous situation which, if not
avoided, could result in death or serious injury to
operator or bystanders.
Indicates a possible hazardous situation which, if not
avoided, may result in moderate or minor injury to
operator or bystanders.
Indicates a condition which, if not avoided, may result
in damage to test equipment or vehicle.
Safety Precautions
!
Type Styles Used:
Safety messages contain three different type styles.
• Normal type states the hazard.
• Bold type states how to avoid the hazard.
• Italic type states the possible consequences of not avoiding the
hazard.
Icons used:
An icon, when present, gives a graphical description of a po te nt ial
hazard.
Example:
Engine systems can malfunction expelling fuel, oil
vapors, hot steam, hot toxic exhaust gases, acid,
refrigerant and other debris.
Safety goggles and protective gloves must be worn
by the operator and any byst anders. Even if everyday
eyeglasses have impact resistant lenses, they are
NOT safety glasses.
•Avoid making an accidental connection between the
battery terminals. Do not place uninsulated metal
tools on the battery.
•When removing battery cables, remove the gro und
cable first.
•Avoid sparks when connecting or disconnecting
power leads to the battery.
•Make sure ignition is off, headlights and other
accessories are off and vehicle doors are closed
before disconnecting the battery cables.
-
This also helps prevent damage to on-board computer systems.
•Always disconnect the battery ground connections
before servicing electrical system components.
Explosion can cause injury.
Risk of poisoning.
•Use this Scan Tool in locations with mechanical
ventilation providing at least 4 air changes per hour .
Engine exhaust contains odorless gas which can be
lethal.
•Route the exhaust outside while testing with the
engine running.
•Block drive wheels before performing a test with
engine running.
•Unless instructed otherwise:
- set parking brake
- put gear selector in neutral for manual transmissions
- put gear selector in park for automatic transmissions
- disconnect release mechanism on the automatic
parking brake release for testing and reconnect when
testing is completed.
• Do not leave a running engine unattended.
A moving vehicle can cause injury.
Risk of equipment or circuit damage.
•Unless specifically directed by manufacturer, make
sure ignition is off before connecting or
disconnecting connectors or any vehicle electrical
terminals.
•Do not create a short between b attery terminals with
a jumper wire or tools.
Improper equipment use can cause equipme nt or circu it
damage.
Misdiagnosis may lead to incorrect or improper repair
and/or adjustment.
•Do not rely on erratic, questionable, or obviously
erroneous test information or results.
- If test information or results are erratic, questionable,
or obviously erroneous, make sure all connections
and data entry information are correct and test
procedures were performed correctly.
- If test information or results are still suspic ious, do
not use them for diagnosis.
Improper repair and/or adjustment may cause vehicle o r
equipment damage or unsafe operation.
Some vehicles are equipped with air bags.
•Follow service manual warnings when working
around air bag components or wiring.
- If service manual instructions are not followed, an air
bag may deploy unexpectedly, resulting in injury.
- Note an air bag can still deploy several minutes after
ignition key is off (or even if vehicle battery is
disconnected) because of a special energy reserve
module.

On-board diagnostics version II (OBD II) is a system that the Society of
Automotive Engineers (SAE) developed to standardize automotive
electronic diagnosis.
Beginning in 1996, most new vehicles sold in the United States were
fully OBD II compliant.
2
✓ Technicians can now use the same tool to test any OBD II
compliant vehicle without special adapters. SAE established
guidelines that provide:
❒ A universal connector, called the DLC, with dedicated pin
assignments.
❒ A standard location for th e DLC, visible under the dash on driver’s
side.
❒ A standard list of diagnostic trouble codes (DTCs) used by all
manufacturers.
❒ A standard list of parameter identification (PID) data used by all
manufacturers.
❒ Ability for vehicle systems to record operating conditions when a
fault occurs.
❒ Expanded diag nostic capabi lities that records a code whenever a
condition occurs that affects vehicle emissions.
❒ Ability to clear stored codes from the vehicle’s memory with a
Scan Tool.
SAE Publications
SAE has published hundreds of pages of text defining a standard
communication protocol that establishes hardware, software, and
circuit parameters of OBD II systems.
• SAE publishes recommendations, not laws, but the Environmental
Protection Agency (EPA) and California Air Resources Board
(CARB) made many of SAE’s recommenda tions legal require ment s.
