SAFETY PRECAUTIONS
SAFETY FIRST!
It is important that every user utilizing this product read all instructions and warnings included within this manual
to ensure your safety, the safety of others, and to prevent damage to this product & vehicles being diagnosed and
repaired. This manual describes common test procedures used by experienced service technicians. It is inferred that
the user has a good understanding of vehicle systems before using this product.
Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to
your vehicle or test equipment. At a minimum, the following safety standards should be followed whenever using this
product, or whenever working on a vehicle.
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 tire 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 tablet
to or disconnecting the tablet 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 ammable. To prevent an explosion, keep all sparks, heated
items, and open ames away from the battery and 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

Press and release DTC/FF/ to view additional stored codes. Each time DTC/FF/ is
pressed and released, the Diagnostic Tool will scroll and display the next DTC in sequence
until all DTCs in its memory have displayed.
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.
NOTE: 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 Diagnostic Tool display is referred to as the PRIORITY code

GLOSSARY
OBD2 Terminology
GLOSSARY
OBD2 TERMINOLOGY
The following terms and their denitions are related to OBD2 systems.
Powertrain Control Module (PCM) - The PCM is the OBD2 accepted term for the vehicle’s “on-board
computer.” In addition to controlling the engine management and emissions systems, the PCM also
participates in controlling the powertrain (transmission) operation. Most PCMs also have the ability to
communicate with other computers on the vehicle (ABS, ride control, body, etc.).
Monitor - Monitors are “diagnostic routines” programmed into the PCM. The PCM utilizes these programs
to run diagnostic tests, and to monitor operation of the vehicle’s emissions-related components or
systems to ensure they are operating correctly and within the vehicle’s manufacturer specications.
Currently, up to fteen Monitors are used in OBD2 systems. Additional Monitors will be added as the
OBD2 system is further developed.
NOTE: Not all vehicles support all fteen Monitors
Enabling Criteria - Each Monitor is designed to test and monitor the operation of a specic part of the
vehicle’s emissions system (EGR system, oxygen sensor, catalytic converter, etc.). A specic set of
“conditions” or “driving procedures” must be met before the computer can command a Monitor to run
tests on its related system. These “conditions” are known as “Enabling Criteria.” The requirements and
procedures vary for each Monitor. Some Monitors only require the ignition key to be turned “On” for them
to run and complete their diagnostic testing. Others may require a set of complex procedures, such
as, starting the vehicle when cold, bringing it to operating temperature, and driving the vehicle under
specic conditions before the Monitor can run and complete its diagnostic testing.
Complete / Incomplete - The terms “Complete” or “Incomplete” are used throughout this manual.
“Complete,” means the PCM has commanded a particular Monitor to perform the required diagnostic
testing on a system to ensure the system is operating correctly (within factory specications). The term
“Incomplete” means the PCM has not yet commanded a particular Monitor to perform diagnostic testing
on its associated part of the emissions system.
Trip - A Trip for a particular Monitor requires that the vehicle is being driven in such a way that all the
required “Enabling Criteria” for the Monitor to run and complete its diagnostic testing are met. The
“Trip Drive Cycle” for a particular Monitor begins when the ignition key is turned “On.” It is successfully
completed when all the “Enabling Criteria” for the Monitor to run and complete its diagnostic testing
are met by the time the ignition key is turned “Off.” Since each of the fteen monitors is designed to
run diagnostics and testing on a different part of the engine or emissions system, the “Trip Drive Cycle”
needed for each individual Monitor to run and complete varies.
OBD2 Drive Cycle - An OBD2 Drive Cycle is an extended set of driving procedures that takes into
consideration the various types of driving conditions encountered in real life. These conditions may
include starting the vehicle when it is cold, driving the vehicle at a steady speed (cruising), accelerating,
etc. An OBD2 Drive Cycle begins when the ignition key is turned “On” (when cold) and ends when the
vehicle has been driven in such a way as to have all the “Enabling Criteria” met for all its applicable
Monitors. Only those trips that provide the Enabling Criteria for all Monitors applicable to the vehicle to
run and complete their individual diagnostic tests qualify as an OBD2 Drive Cycle. OBD2 Drive Cycle
requirements vary from one model of vehicle to another. Vehicle manufacturers set these procedures.
GLOSSARY
OBD2 Monitors
26
Consult your vehicle’s service manual for OBD2 Drive Cycle procedures.
NOTE: Do not confuse a “Trip” Drive Cycle with an OBD2 Drive Cycle. A “Trip” Drive
Cycle provides the “Enabling Criteria” for one specic Monitor to run and complete
its diagnostic testing. An OBD2 Drive Cycle must meet the “Enabling Criteria” for all
Monitors on a particular vehicle to run and complete their diagnostic testing.
Warm-up Cycle - Vehicle operation after an engine off period where engine temperature rises at least
40°F (22°C) from its temperature before starting, and reaches at least 160°F (70°C). The PCM uses
warm-up cycles as a counter to automatically erase a specic code and related data from its memory.
When no faults related to the original problem are detected within a specied number of warm-up cycles,
the code is erased automatically.
OBD2 MONITORS
To ensure the correct operation of the various emissions-related components and systems, a diagnostic program was
developed and installed in the vehicle’s on-board computer. The program has several procedures and diagnostic
strategies. Each procedure or diagnostic strategy is made to monitor the operation of, and run diagnostic tests on, a
specic emissions-related component or system. These tests ensure the system is running correctly and is within the
manufacturer’s specications. On OBD2 systems, these procedures and diagnostic strategies are called “Monitors.”
Currently, fteen Monitors are supported by OBD2 systems. Additional monitors may be added because of Government
regulations as the OBD2 system grows and matures. Not all vehicles support all fteen Monitors. Additionally, some
Monitors are supported by “spark ignition” vehicles only, while others are supported by “compression ignition” vehicles
only.
Monitor operation is either “Continuous” or “Non-Continuous,” depending on the specic monitor.
CONTINUOUS MONITORS
Three of these Monitors are designed to constantly monitor their associated components and/or systems for proper
operation. Continuous Monitors run constantly when the engine is running.
= Comprehensive Component Monitor
= Misre Monitor
= Fuel System Monitor
NON-CONTINUOUS MONITORS
The other twelve Monitors are “non-continuous” Monitors. “Non-continuous” Monitors perform and complete their
testing once per trip.
