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
1iie 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.
Don’t connect or disconnect any test
equipment while the ignition is on or the
engine is running.
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.
2.1 On-Board Diagnostics (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. 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 pieces 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 n 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 n
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 behind
the ashtray And the ashtray must be removed
to access the connector. If the DLC cannot
Be found, refer to the vehicle service manual
for the location.
2.4 OBDII Readiness Monitors
An important part of a vehicle’s OBDII
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 system。They are
running periodic tests on specific systems
and components to ensure that they are
performing within allowable limits.
Currently, there are eleven OBD II Readiness
Monitors (or I/M Monitors). Not all monitors
in any vehicle depends on the motor vehicle
manufacturer emissions control strategy.
Continuous Monitors - Some of the vehicle
components or systems are continuously
tested by the vehicle’s OBD II system。 while
others are tested only under specific vehicle
operating conditions. The 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
components, monitoring key engine sensors,
watching for engine misfire, and monitoring
fuel demands.
Non-Continuous Monitors —Unlike the
continuous monitors, many emissions
and engine system components require
the vehicle to be operated under specific
conditions before the monitor is read.
These monitors are termed non-continuous
monitors. For different ignition type engines
the available monitors are different too.
Once the vehicle is running。the OBD II
system is continuously checking the above
components, monitoring key engine sensors,

Non-Continuous Monitors —Unlike the
continuous monitors, many emissions
and engine system components require
the vehicle to be operated under specific
conditions before the monitor is read.
These monitors are termed non-continuous
monitors. For different ignition type engines
the available monitors are different too.
The following monitors are to be used for
spark ignition (Petrol) engines only:
1) EGR System
2) 02 Sensors
3) Catalyst
4) Evaporative System
5) 02 Sensor Heater Q 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 after treatment
4) Boost pressure system
5) Exhaust gas sensor
6) PM filter
2.5 OBDII Monitor Readiness Status
OBD n systems must indicate whether or
not the vehicle’s PCM’s monitor system has
completed testing on each component .
Components that have been tested will be
reported as “Ready”。or “Complete” meaning
they have been tested by the OBDII system.
The 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 “Complete” after an
appropriate drive cycle has been performed .
The 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 state. A number of factors, including
erasing of diagnostic trouble codes (DTCs)
with a scan tool or a disconnected battery,
continuous monitors ; can result in Readiness
Monitors being set to “Not Ready”. Since
the three 。constantly evaluating, they will be
reported as “Ready” all of the time. if testing
of a particular supported non-continuous
monitor has not been completed。the monitor
status will be reported as “Not Complete” or
“Not Ready”.
In order for the OBD monitor system to
become ready, the vehicle should be driven
under 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-off period.
For specific information on getting your
vehicle’s OBD monitor system ready, please
consult your vehicle owner’s manual.

2.6 OBD II Definitions
Power-train Control Module (PCM) - OBD n
terminology for the on-board Computer that
controls engine and drive train.
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 not turn the MIL off necessary re
airs 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
Conditions. They are the vehicle-specific
events or conditions that must occur within
the engine before the various monitors will
set» or run. Some 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 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 detected。Drive cycles vary
depending on the vehicle and the monitor
that needs to be reset。 For vehicle specific
drive cycle, consult the vehicle’s Owner’s
Manual.
Freeze Frame Data — When an emissions
related fault occurs, the OBD II system not
only sets a code but also records a snapshot
of the vehicle operating parameters to help
in identifying the problem. This set of values
is referred to as Freeze Frame Data and may
include important engine parameters such as
engine RPM, vehicle speed, airflow, engine
load, fuel pressure, fuel trim value> engine
coolant temperature, ignition timing advance,
or closed loop status.
2.7 OBD II Modes of Operation
Here is a basic introduction to the OBD n
communication protocols Mode byte : The
first byte in the stream is the mode number.
There are 10 modes for diagnostic requests
. The first byte in the response data bytes
is this same number plus 64.For example,a
mode 1 request would have the first data
byte =1, and the response would have the
first data byte=65.
Mode $01 - Identifies the Power train
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
one are not implemented in this mode.
Mode $03 - Displays the type of power train
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
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 02 sensor threshold
voltage.
2. $02 Lean-to-Rich 02 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.
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 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,
test or component bi-directionally (where
applicable). This mode is manufacturer
specific.

10 11
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 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.
