1.Safety Precautions and Warnings
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:
●Always perform automotive testing in a safe environment.
●Do not attempt to operate or observe the tool while driving a vehicle. Operating
or observing the tool will cause driver distraction and could cause a fatal
accident.
●Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
●Wear safety eye protection that meets ANSI standards.
●Operate the vehicle in a well ventilated work area: Exhaust gases are
●Use extreme caution when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous voltages
●Put the transmission in PARK (for automatic transmission) or NEUTRAL
(for manual transmission) and make sure the parking brake is engaged.
●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.
●Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
●Don't connect or disconnect any test equipment while the ignition is on or the
engine is running.

2.1 On-Board Diagnostics (OBD) II
2.2 Diagnostic Trouble Codes (DTCs)
1) Whether the Malfunction Indicator Light (MIL) is commanded 'on' or 'O';
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
The first generation of On-Board Diagnostics (called OBD I) was developed by
the California Air Resources Board (CARB) 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
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. 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 “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 below follow three pieces
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board
computer diagnostic system in response to a problem found in the vehicle. These
codes identify a particular problem area and are intended to provide you with a
guide as to where a fault might be occurring within a vehicle. OBD II Diagnostic
Trouble Codes consist of a five-digit alphanumeric code. The first character, a letter,
identifies which control system sets the code. The other four characters, all
numbers, provide additional information on where the DTC originated and the
operating conditions that caused it to be set. Below is an example to illustrate the

Readiness Monitors are indicators used to find out if all of the emissions

tests on specific systems and components to ensure that they are performing
Currently, there are eleven OBD II Readiness Monitors (or l/M Monitors) defined
by the U.S. Environmental Protection Agency (EPA). Not all monitors are supported
by all vehicles and the exact number of monitors in any vehicle depends on the

continuously tested by the vehicle’s OBD II system, while others are tested only
under specific vehicle operating conditions. The continuously monitored

OBD II tested will be reported as “OK”. The purpose of recording readiness status is
to allow inspectors to determine if the vehicle’s OBDII system has tested all the
emissions systems. This is handy to know before bringing vehicle to a state
In order for the OBD monitor system to become ready, the vehicle should be
driven under a variety of normal operating conditions. These operating conditions
may include a mix of highway driving and stop and go, city type driving, and at
least one overnight-o period. For specific information on getting your vehicle’s

Malfunction Indicator Light (MIL) – Malfunction Indicator Light (Service Engine
Soon, Check Engine) is a term used for the light on the instrument panel. It is to
alert the driver and/or the repair technician that there is a problem with one or
more of vehicle’s systems and may cause emissions to exceed federal standards.
If the MIL illuminates with a steady light, it indicates that a problem has been
detected and the vehicle should be serviced as soon as possible. Under certain
conditions, the dashboard light will blink or flash. This indicates a severe problem
and flashing is intended to discourage vehicle operation. The vehicle onboard
diagnostic system can’t turn the MIL o until necessary repairs are completed or
The powertrain control module (PCM) sets a monitor to “OK” after an
appropriate drive cycle has been performed. The drive cycle that enables a Monitor
and sets readiness codes to “OK” varies for each individual monitor. Once a monitor
is set as “OK”, it will remain in this state. A number of factors, including erasing of
diagnostic trouble codes (DTCs) with a code reader or a disconnected battery, can
result in Readiness Monitors being set to “INC” (incomplete). Since the three
continuous monitors are constantly evaluating, they will be reported as “OK” all of
the time. As long as there are no DTCs stored in memory, the vehicle is running in
accordance with the OBD II guidelines. If testing of a particular support

OBD II Drive Cycle – A specific mode of vehicle operation that provides
conditions required to set all the readiness monitors applicable to the vehicle to the
“ready” condition. The purpose of completing an OBD II drive cycle is to force the
vehicle to run its onboard diagnostics. Some form of a drive cycle needs to be
performed after DTCs have been erased from the PCM’s memory or after the battery
has been disconnected. Running through a vehicle’s complete drive cycle will “set”
the readiness monitors so that future faults can be detected. Drive cycles vary
depending on the vehicle and the monitor that needs to be reset. For vehicle

The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized
16-cavity connector where diagnostic scan tools interface with the vehicle's
on-board computer. The DLC is usually located 12 inches from the center of the
instrument panel (dash), under or around the driver's side for most vehicles. If the
Data Link Connector is not located under the dashboard, a label should be there
revealing its location. For some Asian and European vehicles, the DLC is located
behind the ashtray and the ashtray must be removed to access the connector. If the
DLC cannot be found, refer to the vehicle's service manual for the location.

the area of the car interior seen at right (black arrow).
