Important Safety Information
To prevent personal injury or damage to vehicles and/or the Scan Tool, read this
instruction manual first and observe the following safety precautions, at a minimum,
whenever working on a vehicle:
1. Always perform automotive testing in a safe environment.
2. Wear safety eye protection.
3. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
4. Operate the vehicle in a well ventilated work area. Exhaust gases are poisonous.
5. Put blocks in front of the drive wheels and never leave the vehicle unattended while
running tests.
6. 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.
7. Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
8. Keep a fire extinguisher suitable for gasoline/ chemical/ electrical fires nearby.
9. Don't connect or disconnect any test equipment while the ignition is on or the engine
is running.
10. 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.
Service
There are no user serviceable parts. Scan Tool service must be performed only by qualified
repair personnel.

Overview
OBD II On-Board Diagnostics
The first generation of On-Board
Diagnostics (called OBDI) was developed
by the California Air Resources Board
(ARB) and implemented in 1988 to monitor
some of the emission control components
on vehicles. As technology evolved and
the desire to improve the On-Board
Diagnostic system increased, a new
generation of On-Board Diagnostic system
was developed. This second generation of
On-Board Diagnostic regulations is called
"OBD II".
The OBD II system is designed to monitor
emission control systems and key engine
components by performing either
continuous or periodic tests of specific
components and vehicle conditions.
Vehicle Coverage
This Scan Tool 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.
When a problem is detected, the OBD II
system turns on a warning lamp (MIL) on
the vehicle instrument panel to alert the
driver typically by the phrase of “Check
Engine” or “Service Engine Soon”.
The system will also store important
information about the detected malfunction
so that a technician can accurately find and
fix the problem. Here are three examples:
1. Whether the Malfunction Indicator
Light (MIL) is commanded 'on' or 'off';
2. Which, if any, Diagnostic Trouble
Codes (DTCs) are stored;
3. Readiness Monitor status.
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.

Definitions
• EOBD: European On-Board
Diagnostics
Essentially the same as OBD II, with
the same Data Link Connector and
Communication Protocols.
• Communication Protocol: Allows
different systems and sensors in a
vehicle to communicate.
There are currently five Protocols:
CAN Bus
J1850 VPW
ISO 9141-2
J1850 PWM
ISO 14230 KWP
• CAN: Controller Area Network
Message-based Communication
Protocol serial bus.
• CAN Vehicle
2008 and newer.
• Pre-CAN Vehicle
2007 and older.
• DLC: Data Link Connector
The 16-cavity connector on the vehicle
that allows communication between the
computer system and the Scan Tool.
Control
Modules
• Drive Cycle
A set of driving procedures that,
when met, provide the Enabling
Criteria for the I/M Monitors to run
and complete their diagnostic tests.
• Enabling Criteria
Operating conditions that must
occur during a Drive Cycle to
cause the I/M Monitors to run and
complete their diagnostic tests.
• MIL: Malfunction Indicator Lamp
The vehicle’s “Check Engine”
warning light that activates
when a DTC is stored.
• DTC: Diagnostic Trouble Code
A code stored in the computer
system’s memory, which helps to
identify the fault condition that is
causing the MIL to activate.
• Freeze Frame Data
Operating conditions that are
stored when a DTC is stored.
• PID - Parameter Identification Data
Data returned by the vehicle’s
Control Modules to the Scan Tool.
Control Modules are individual computers that operate and monitor different
systems in the vehicle. Control Modules vary depending on manufacturer.
ID codes are assigned to each Control Module, which are
defined by the vehicle’s Communication Protocol.
For example, a vehicle may use ID code $7E8 for the PCM and $7E9 for the TCM.

sub-systems of the vehicle.
There are two types of Monitors:
• Continuous: Monitors that
perform tests all the time while
the engine is running.
Gasoline Engine
Monitors
Continuous
MIS - Misfire
FUEL - Fuel System
CCM - Comprehensive Components
• Non-Continuous: Monitors that require
specific operating conditions to be met
during a Drive Cycle in order for the
Monitors to run their testing sequences.
Note: Not all Monitors are supported
by all vehicles.

Diagnostic Test Modes
Diagnostic Test Modes as described in the latest OBD II standard SAE J1979.
Note: Not all Modes are supported by all vehicles.
Mode $01 – Identifies the Powertrain
information and shows current data
available to the Scan Tool. This data
includes: DTC set, status of on-board tests,
and vehicle data such as engine RPM,
temperatures, ignition advance, speed, air
flow rates, and closed loop status for fuel
system.
Mode $02 –Displays Freeze Frame Data.
Same data as in mode 1, but it was
captured and stored when a malfunction
occurred and a DTC was set. Some of the
PIDs for Mode $01 are not implemented in
this mode.
Mode $03 –Displays the type of
Powertrain or emission related DTCs
stored by a 5 digit code identifying the
faults. There may be more than one
response message if there are more
trouble codes than will fit in the data bytes
of the response message, or if there are
more than one ECU computer responding.
Mode $04 –Used to clear DTCs and
Freeze Frame Data. This clears all DTCs
that may be set including freeze frame
data and Readiness Monitors.
Mode $05 –Oxygen Sensor Test Results.
This mode displays the oxygen sensor
monitor screen and the test results
gathered about the oxygen sensor.
Mode $06 –Non-Continuously Monitored
Systems test results. There are typically a
minimum value, a maximum value, and a
current value for each non-continuous
monitor. This data is optional, and it is
defined by a given vehicle maker if it's used.
Mode $07 –Request for DTCs (pending)
from Continuously Monitored Systems
after a single driving cycle has been
performed to determine if repair has fixed
aproblem. This is used by service
technicians to verify repair was performed
properly and after clearing DTCs.
Mode $08 –This special Control Mode
requests control of the on-board system,
test, or component bi-directionally (where
applicable). This mode is manufacturer
specific.
Mode $09 –Reports vehicle information.
This information includes vehicle VIN number
and calibration information stored in the
vehicle ECUs.
Mode $0A –Request Emission-Related
Diagnostic Trouble Codes with Permanent
Status. This mode is required for all
emissions-related DTCs. The presence of
permanent DTCs at an inspection without the
MIL illuminated is an indication that a proper
repair was not verified by the on-board
monitoring system.

Diagnostic Trouble Code
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.
