WaRNING! To prevent personal injury or damage to vehicles and/or the scan tool, read this instruction manual rst and observe the
following safety precautions.
9 Always perform automotive testing in a safe environment.
9 Wear safety eye protection.
9 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
9 operate the vehicle in a well ventilated work area. exhaust gases are poisonous.
9 Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
9 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.
9 Put the transmission in PArK (for automatic transmission) or neutrAL (for manual transmission) and make sure the parking brake
is engaged.
9 Keep a re extinguisher suitable for petrol/chemical/electrical res nearby.
8 DO NOT connect or disconnect any test equipment while the ignition is on or the engine is running.
9 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.
3. GENERaL INFORMaTION
3.1. On-Board Diagnostics EOBD
the eoBd system is designed to monitor emission control systems and key engine components by performing either continuous or
periodic tests of specic components and vehicle conditions. When a problem is detected, the EOBD system turns on a warning lamp
on the vehicle instrument panel to alert the driver typically by the phrase of "check engine". the system will also store important
information about the detected malfunction so that a technician can accurately nd and x the problem.
3.2. Diagnostic Trouble Codes
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. eoBd Diagnostic Trouble Codes consist of a ve-digit alphanumeric code. The rst character,
a letter, identies 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 digits:
dtc example
Systems
B=Body
c=chassis
P=Powertrain
u=network
code type
Generic (SAE):Manufacturer Specic:
P0, P2, P34-P39 P1, P30-p33
B0, B3 B1, B2
c0, c3 c1, c2
u0, u3. u1, u2
3.3. 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 on-board computer. the dLc is usually located 30cm from the center of the instrument panel (dash),
under or around the driver's side for most vehicles. If data Link connector is not located under dashboard, a label should be there
telling the 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.
3.4. EOBD Readiness Monitors
An important part of a vehicle's EOBD system is the Readiness Monitors, which are indicators used to nd out if all of the emissions
components have been evaluated by the EOBD system. They are running periodic tests on specic systems and components to
ensure that they are performing within allowable limits.
not all monitors are supported by all vehicles and the exact number of monitors in any vehicle depends on the motor vehicle
manufacturer's emissions control strategy.
continuous monitors - Some of the vehicle components or systems are continuously tested by the vehicle's eoBd system, while
others are tested only under specic vehicle operating conditions. The continuously monitored components listed below are always
ready:
1. Misre
2. fuel System
3. comprehensive components (ccm)
once the vehicle is running, the eoBd system is continuously checking the above components, monitoring key engine sensors,
watching for engine misre and monitoring fuel demands.
non-continuous monitors - unlike the continuous monitors, many emissions and engine system components require the vehicle to

be operated under specic conditions before the monitor is ready. These monitors are termed non-continuous monitors and are listed
below:
1) eGr System
2) o2 Sensors
3) catalyst
4) evaporative System
5) o2 Sensor Heater
6) Secondary air
7) Heated catalyst
8) A/c system
3.5. EOBD Monitor Readiness Status
eoBd 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 eoBd system.
the purpose of recording readiness status is to allow inspectors to determine if the vehicle's eoBd 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, can result in readiness monitors being set to "not ready". Since the three continuous monitors
are 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 eoBd monitor system to become ready, the vehicle should be driven under 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
specic information on getting your vehicle's EOBD monitor system ready, please consult your vehicle owner's manual.
3.6. EOBD Denitions
Powertrain control module (Pcm) - eoBd terminology for the on-board computer that controls engine and drive train. malfunction
Indicator Light (mIL) - malfunction Indicator Light (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 standards. If the mIL illuminates with a steady light, it indicates that a problem has been detected and the vehicle
should be repaired as soon as possible. Under certain conditions, the dashboard light will blink or ash. This indicates a severe
problem and ashing is intended to discourage vehicle operation. The vehicle on board diagnostic system can not turn the MIL off until
necessary repairs 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-specic events or conditions that must occur within the
engine before the various monitors will set, or run. Some monitors require the vehicle 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.
EOBD Drive Cycle - A specic 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 eoBd 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 specic drive cycle,
consult the vehicle's owner's manual.
freeze frame data - When an emissions related fault occurs, the eoBd 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, air ow, engine load, fuel pressure, fuel trim value, engine
coolant temperature, ignition timing advance, or closed loop status.
3.7. EOBD Modes of Operation
Introduction to the eoBd communication protocol.
Mode $01 - Identies the Powertrain information and shows current data available to the scan tool. This data includes: DTCs set, status of
on-board tests and vehicle data such as engine RPM, temperatures, ignition advance, speed, air ow 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 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 t in the data bytes of the response message, or if there are more
than one Pcm 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-Lean 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 dened by a given vehicle make 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 xed 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 specic.
mode $09 - reports vehicle information. this information includes vehicle VIn number and calibration information stored in the vehicle
Pcms.
mode $10 - 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 veried
by the on-board monitoring system.

5.1. Read Codes
reading codes can be done with the key on engine off or with the key on engine running.
Stored codes are also known as “permanent codes”. these codes cause the control module to illuminate the malfunction indicator light
(mIL) when emission-related fault occurs.
Pending codes are also referred to as “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 lamp (mIL). If
the fault does not occur within a certain number of warm-up cycles, the code clears from memory.

5.5. I/M Readiness
I/m readiness function is used to check the operation of the emission System on eoBd compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected.
CaUTION - By clearing trouble codes you also clear the readiness status for the individual emission system readiness tests. In order
to reset these monitors, the vehicle must be driven through a complete drive cycle with no trouble codes in the memory. times for
reset vary depending on vehicle.
Some latest vehicle models may support two types of I/m readiness tests:
A. Since dtcs cleared - indicates status of the monitors since the dtcs are erased.
B. this drive cycle - indicates status of monitors since the beginning of the current drive cycle.
An I/m readiness Status result of “no” does not necessarily indicate that the vehicle being tested will fail the I/m inspection.
one or more such monitors may be allowed to be “not ready” to pass the emissions inspection.
“oK” - Indicates that a particular monitor being checked has completed its diagnostic testing.
“Inc” - Indicates that a particular monitor being checked has not completed its diagnostic testing.
“n/A” - the monitor is not supported on that vehicle.
1) use the ScroLL button to select I/m readiness from diagnostic menu and press enter button.
2) Wait a few seconds while the scan tool validates the PId mAP.
3) If the vehicle supports both types of tests, then both types will be shown on the screen for selection.

1) to exit eoBd test, use ScroLL button to select Previous menu from diagnostic menu and press enter/eXIt button.
2) A warning message comes up asking your conrmation. Press ENTER button to exit.
6. I/M REaDINESS
There are two modes to show I/M readiness monitor status. You can congure work modes in the Setup menu.
1). Scan tool mode
Scan tool mode is the default work mode. In this mode, after the vehicle's monitors have run and completed their diagnosis and
testing, the scan tool will turn to eoBd diagnostic procedures.
note: only in this mode can you perform the eoBd diagnostics.
2). ready test mode
In this mode, after the vehicle's monitors have run and completed their diagnosis and testing, the scan tool will return to the previous
screen. So it is onLY used to check the emission-related monitors' status.
note: this function reads off the real time data of emission-related monitoring systems readiness status every two minutes. once

the scan tool has nished other operations, for example, clearing trouble codes, and the I/M Readiness Status indication will
change accordingly. In order to reset these monitors, the vehicle must be driven through a complete drive cycle. times for reset vary
depending on vehicle.
6.1. Ready Test Mode
repairs to the emissions-control systems of a 2001 or newer vehicle cause the vehicle's computer (Pcm) memory to be cleared.
the vehicle must go through a drive cycle to allow the Pcm to perform a series of tests to ensure that the repair was successful, and
before a emissions test can be conducted.
modern vehicles lack equipment to indicate whether the tests have been completed. With the auto code reader, you don't have to bring
the vehicle back to the workshop for retest if all required tests by the Pcm are completed.
In the ready test mode, you can easily check the I/m readiness status to determine whether an eoBd vehicle is ready for an
emission test.
to enter this mode, simply press the one-click Key at anytime. If the one-click function key is set at I/m readiness. or while the
scan tool in ready test mode, select diagnostics in the main Screen. If the scan tool is idle, it will show the result immediately. If it is
busy, it will wait till the current procedure has nished. After viewing the status, press I/M Readiness One-Click Key or ENTER button
to exit, which takes a few seconds. You will get the information screen as below.
“oK” -- Indicates that a particular monitor being checked has completed its diagnostic testing.
“Inc” -- Indicates that a particular monitor being checked has not completed its diagnostic testing.
“n/A” -- the monitor is not supported on the vehicle.
the Led and audio tone indications are as interpreted below:
LED Interpretation
the green and red Leds provide an easy way to check if emission-related monitoring systems complete their self-diagnostic testing.
1) Green Led – Indicates that engine systems are “oK” and operating normally (the number of monitors supported by the vehicle
which have run and performed their self-diagnostic testing is in the allowed limit).
2) red Led – Indicates that the number of monitors supported by the vehicle which have run and performed their self-diagnostic
testing is out of the allowed limit.
audio Tone Interpretation
The audio tone could be congured according to the I/M Readiness Status. This function is invaluable when working in bright areas
where LED illumination alone is not sufcient.
Led Light Audio tone Beep Interval
Green Led Bleep off
Yellow Led two short Beeps 0.5 Second
red Led two short Beeps 0.5 Second
6.2. Scan Tool Mode
NOTE: only in this mode can you perform eoBd diagnostics.
to enter this mode, please follow the steps in section retrieving I/m readiness Status.
the green, yellow and red Leds provide a quick way to help you determine if a vehicle is ready for an emission test.
the Led and audio tone indications are as interpreted below:
Led Interpretation
1) Green Led – Indicates that engine systems are “oK” and operating normally (the number of monitors supported by the vehicle
which have run and performed their self-diagnostic testing is in the allowed limit mIL is off).there are no stored and pending dtcs.
the vehicle is ready for an emissions test.
2) YeLLoW Led – With mIL off, there may be three possible conditions to cause the yellow Led to light.
If a “Stored” diagnostic trouble code is causing the Yellow Led to light, it is still possible that the vehicle can be tested for emissions.
If a “Pending” diagnostic trouble code is causing the Yellow Led to light, it is still possible that the vehicle will be allowed to be tested
for emissions.

3) RED LED – Indicates there is a problem with one or more of the vehicle's system. A vehicle displaying a red LED is denitely not
ready for an emissions test. the red Led is also an indication that there are dtcs present. the mIL lamp on the vehicle's instrument
panel will be lit. the problem that is causing the red Led to light must be repaired before an emissions test can be performed.
audio Tone Interpretation
The audio tone could be congured according to the I/M Readiness Status. This function is invaluable when working in bright areas
where LED illumination alone is not sufcient. It is recommended to set the audio tone to Beep ON. For detailed setup information,
please refer to Status Beep Set System Setup.
note: the following audio tone description only works in Scan tool mode.
different audio tone with different Led lights will indicates different I/m readiness Status.
