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.
. Wear safety eye protection that meets ANSI standards.
. Keep clothing,hair,hands,tools,test equipment,etc. away from all
moving or hot engine parts.
. Operate the vehicle in a well-ventilated work area:Exhaust gases are
poisonous.
. Put blocks in front of the drive wheels and never leave the vehicle
unattended
while running tests.
. 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.
. Put the transmission in P(for A/T) or N(for M/T) and make sure the
parking brake is engaged.
. Keep a fire extinguisher suitable for gasoline/chemical/electrical
fires nearby.

2. General Information
2.1 On-Board DiagnosticsOBDII
The first generation of On-Board Diagnostics(calle OBD I) 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 eigher 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
of “Check Engine” or “Service Engine Soon”. The system will also
store important information about the detected malfunction so follow
three pices of such valuable information:
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.
2.2 Diagnostic Trouble Codes (DTCs)
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
consists 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 set. Here below is an example to illustrate the structure
of the digits:
2

.3 Location of the Data Link Connector(DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic scan tools interface
with the vehicle’s side for most vehicles. If Data Link Connector is not
located under dashboard, a label should be there telling location. For
some Asian and European vehicles, the DLC is located behine 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.

2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBD II system is the Readiness Monitors
which are indicators used to find out if all of the emissions components have
been evaluated by the OBD II systemThey are running periodic tests on
specific systems and components to ensure that they are performing within
allowable limits
Currentlythere are eleven OBD II Readiness Monitors (or I/M Monitors)
defined by the U.SEnvironmental Protection Agency (EPA) Not all
monitors in any vehicle depends on the motor vehicle manufacturers
emissions control stragtegy
Continuous Monitors – Some of the vehicle components or systems are
continuously tested by the vehicle’s OBD II systemwhile others are tested
only under specific vehicle operating conditionsThe continuously monitored
components listed below are always ready:
1) Misfire
2) Fuel System
3) Comprehensive Components(CCM)
Once the vehicle is running the OBD II system is continuously checking
the above componentsmonitoring key engine sensorswatching for engine
misfireand monitoring fuel demands
Non-Continuous Monitors –Unlike the continuous monitorsmany
emissions and engine system components require the vehicle to be operated
under specific conditions before the monitor is readThese monitors are
termed non-continuous monitorsFor different ignition type enginesthe
available monitors are different too
4
The following monitors are to be used for spark ignition (Gasoling) engines
only:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air
7) Heated Catalyst
The following monitors are to be used for compression ignition (Diesel)
engines only:
1
EGR System
2
NMHC Catalyst
3
NOx aftertreatment
4
Boost pressure system
5
Exhaust gas sensor
6
PM filter
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM’s monitor
system has completed testing on each componentComponents that have
heen tested will be reported as “Ready”or “Complete”meaning they have
been tested by the OBD II systemThe purpose of recording readiness status
is to allow inspectors to determine if the vehicle’s OBD II system has tested
all the components and/or systems
The power-train control module (PCM) sets a monitor to “Ready” or
“Completeafter an appropriate drive cycle has been performedThe drive
cycle that enables a monitor and sets readiness codes to “Ready” varies for
each individual monitor Once a monitor is set as “Ready” or “Complete”
it will remain in this stateA number of factorsincluding erasing of
diagnostic trouble codes (DTCs) with a scan tool or a disconnected battery
can result in Readiness
Monitors being set to “Not Ready”Since the three
continuous monitors are constantly evaluatingthey will be reported as
“Ready” all of the timeif testing of a particular supported non-continuous
monitor has not been completedthe monitor status will be reported as “Not
Complete” or “Not Ready”
In order for the OBD monitor system to become readythe vehicle should be
driven under variety of normal operating conditions These operating
conditions may include a mix of highway driving and stop and gocity type
drivingand at least one overnight-off periodFor specific information on
getting your vehicle’s OBD monitor system readyplease consult your
vehicle owners manual

2.6 OBD II Definitions
Power-train Control Module (PCM) – OBD II terminology for the on-board
Computer that controls engine and drive train
Malfunction Indicator Light (MIL) – Malfunction Indicator Light (Service
Engine SoonCheck Engine) is a term used for the light on the instrument
panelIt 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 standardsIf the MIL illuminates with a steady lightit
indicates that a problem has been detected and the vehicle should be serviced
as soon as possibleUnder certain conditionsthe dashboard light will blink
or flashThis indicates a severe problem and flashing is intended to
discourage vehicle operationThe vehicle onboard diagnostic system can not
turn the MIL off necessary reairs are completed or the condition no longer
exists
DTC Diagnostic Trouble Codes (DTC) that identify which section of the
emission control system has malfunctioned
Enabling Criteria Also termed Enabling ConditionsThey are the
vehicle-specific events or conditions that must occur
within the engine before
the various monitors will setor runSome monitors require the various to
follow a prescribed “drive cycle” routine as part of the enabling criteria
Drive cycles vary among vehicles and for each monitor in any particular
vehicle
OBD II Drive Cycle A specific mode of vehicle operation that
provides conditions required set all the readiness monitors completing and
OBD II drive cycle is to force the vehicle to run its onboard diagnostics
Some 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 detectedDrive cycles vary depending
on the vehicle and the monitor that needs to be resetFor vehicle specific
drive cycleconsult the vehicle’s
Owners Manual
Freeze Frame Data
When an emissions related fault occursthe OBD
II system not only sets a code but also records a snapshot of the vehicle
operating parameters to help in identifying the problemThis set of values is
referred to as Freeze Frame Data and may include important engine
parmeters such as engine RPMvehicle speedair flowengine loadfuel
pressurefuel trim valueengine coolant temperatureignition timing
advanceor closed loop status
6
2.7 OBD II Modes of Operation
Here is a basic introduction to the OBD II communication protocol
Mode byte : The first byte in the stream is the mode numberThere are 10
modes for diagnostic requestsThe first byte in the response data bytes is this
same number plus 64For examplea mode 1 request would have the first
data byte =1and the response would have the first data byte=65Here is a
brief description of the modes :
Mode $01 Identifies the Powertrain information and shows current
data available to the scan tool
This data includes: DTC setstatus of
on-board testsand vehicle data such as engine RPMtemperaturesignition
advancespeedair flow ratesand closed loop status for fuel system
Mode $02 – Displays Freeze Frame data
Same data as in mode 1but it
was captured and stored when a malfunction occurred and a DTC was set
Some of the PIDs for mode one 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 messageor it there are more than one ECU computer
responding
Mode $04 Used to clear DTCs and Freeze Frame data. This clears all
diagnostic trouble codes 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
There are ten numbers available for diagnostics:
1. $01 Rich-to-Lean O2 sensor threshold voltage.
2. $02 Lean-to-Rich O2 sensor threshold voltage.
3. $03 Low sensor voltage threshold for switch time measurement.
4. $04 High sensor voltage threshold for switch time measurement.
5. $05 Rich-to-Rich switch time in ms.
6. $06 Lean-to-Rich switch time in ms.
7. $07 Minimum voltage for test.
8. $08 Maximum voltage for test.
9. $09 Time between voltage transitions in ms.
7
Mode $06 Non-continuously Monitored Systems test results. There are
typically a minimum valuea maximum valueand a current value for each
non-continuous monitorThis data is optionaland 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 a problem. This is used by service technicians to verify
repair was performed properly and after clearing diagnostic trouble codes
Mode $08 This special Control Mode requests control of the on-board
system
testor 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 Throuble Code with
Permanent Status. This 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

3.8 Vehicle Coverage
The scan tool is specially designed to work with all OBD II compliant
vehiclesincluding control area network (CAN)it is required by EPA
that all 1996 and newer vehicles (Cars and light trucks) sold in the
united states must be OBD II compliant and this includes all american
asian and European vehicles
A small number of 1994 and 1995 model year gasoline vehicles are OBD
II compliantTo verify if a 1994 or 1995 vehicle is OBD II compliant
check the vehicle emissions control information(VECI) Labelwhich is
located under the hood or by the radiator of most vehiclesIf the vehicle
is OBD II compliantthe label will designate “OBD II Certified”
Additionally Government regulations mandate that all OBD II
compliant vehicles must have a “common” sixteen-pin Data Link
Connector (DLC)
For the vehicle to be OBD II compliant is must
have a 16-pin DLC (Data
Link Connector) under the dash and the vehicle emission control
information label must state that the vehicle is OBD II compliant
4. OPERATION
1) Turn the ignition off.
2) Locate the vehicle’s 16-pin Data Link Connector(DLC).

2) Pending DTCs:
Pending DTCs are also referred to as “maturing codes” or “continuous
monitor codes” . They indicate problems that the control module has detected
during the current or last driving cycle but are not considered serious yet.
Pending codes will not turn on the malfunction indicator light (MIL) . If the
fault does not occur within a certain number of warm-up cycles, the code
clear from memory.
3) Permanent DTCs:
Permanent DTCs are codes that are “confirmed” and are retained in the
