3 Getting Started
3.1 Introduction
The scan tool was developed by experts in the automo-
tive service industry to help diagnose vehicles and assist
in troubleshooting procedures.
The scan tool monitors vehicle events and retrieves
codes from the vehicle’s control modules to help pin-
point problem areas.
All information, illustrations and specifications contained
in this manual are based on the latest information avail-
able from industry sources at the time of publication.
No warranty (expressed or implied) can be made for its
accuracy or completeness, nor is any responsibility
assumed by the manufacturer or anyone connected with
it for loss or damages suffered through reliance on any
information contained in this manual or misuse of
accompanying product. The manufacturer reserves the
right to make changes at any time to this manual or
accompanying product without obligation to notify any
person or organization of such changes.
3.2 Download Scanning Suite
1.
Download the Scanning Suite PC application.
Scan-ning Suite is NOT required to operate the
scan tool.
2. Install the downloaded Scanning Suite application
before connecting the scan tool to the PC.
To be able to use Scanning Suite the PC must meet
the following minimum requirements:
• Microsoft Windows XP, Vista, 7, and 8
• Adobe Acrobat Reader
• Screen Resolution of 800 x 600
– If screen resolution is 800 x 600, in Display
Properties, Settings Tab, set Font Size to

3. Use Scanning Suite to determine if any updates are avail-
able for your tool by clicking Check for Update button.
4. Check for updates to Use Scanning Suite by clicking
on the Check For Scanning Suite Update button. This
should be done before checking for Tool Updates.
You can also configure the Scanning Suite Frequency (SS
Frequency) to automatically check every xx minutes.
3.3 OBDII
On-board diagnostics version II (OBDII) is a system that
the Society of Automotive Engineers (SAE) developed to
standardize automotive electronic diagnosis.
Beginning in 1996, most new vehicles sold in the United
States were fully OBDII compliant.
Technicians can now use the same tool to test any OBDII
compliant vehicle without special adapters. SAE estab-
lished guidelines that provide:
• A universal OBDII data link connector, called the
DLC, with dedicated pin assignments.
• A standard location for the DLC, visible under the
dash on driver’s side.
• A standard list of diagnostic trouble codes (DTCs)
used by all manufacturers.
• A standard list of parameter identification (PID) data
used by all manufacturers.
• Ability for vehicle systems to record operating condi-
tions when a fault occurs.
• Expanded diagnostic capabilities that records a
code whenever a condition occurs that affects
vehicle emissions.
• Ability to clear stored codes from the vehicle’s
memory with a scan tool.
3.4 SAE Publications
SAE has published hundreds of pages of text defining a
standard communication protocol that establishes hard-
ware, software, and circuit parameters of OBDII sys-
tems. Unfortunately, vehicle manufacturers have differ-
ent interpretations of this standard communications
protocol. As a result, the generic OBDII communications
scheme varies, depending on the vehicle. SAE publishes
recommendations, not laws, but the Environmental
Protection Agency (EPA) and California Air Resources
Board (CARB) made many of SAE’s recommendations
legal requirements that vehicle manufacturers were
required to phase in over a three-year period. Beginning
in 1994, vehicles with a new engine management com-
puter (about 10% of each manufacturers fleet) were sup-
posed to comply with OBDII standards. For 1995, OBDII
systems were to appear on about 40% of the new vehi-
cles sold in the United States. Some of the 1994-1995
OBDII systems were not fully compliant, so the Govern-
ment granted waivers to give manufacturers time to
fine-tune their systems. Beginning in 1996, most of the
new vehicles sold in the United States were fully OBDII
compliant.
3.5 OBDII Data Link Connector (DLC)
The OBDII data link connector (DLC) allows the scan
tool to communicate with the vehicle’s computer(s).
Beginning in 1996, vehicles sold in the United States use
the J1962 (OBDII) DLC, a term taken from a physical
and electrical specification number assigned by the SAE
(J1962). The DLC should be located under the dash-
board on the driver’s side of the vehicle. If the DLC is
not located under the dashboard as stated, a decal
describing its location should be attached to the dash-
board in the area the DLC should have been located.

3.6 OBDII Diagnostic Trouble Codes
(DTCs)
J2012 and ISO 15031-6 are standards for all DTCs,
established by the SAE, International Organization for
Standardization (ISO) and other governing bodies.
• Codes and definitions assigned by these specifica-
tions are known as Generic OBDII codes.
• OBDII requires compliance to these standards for all
cars, light trucks, APVs, MPVs, and SUVs sold in the
United States.
• Codes not reserved by the SAE are reserved for the
manufacturer and referred to as Manufacturer Spe-
cific Codes.
DTCs are used to help determine the cause of a problem
or problems with a vehicle.
• DTCs consist of a five-digit alphanumeric code.
• The DTC format and general code types are shown below.

5.1 I/M Monitors (Emissions)
The I/M Monitors (Inspection / Maintenance) function is
used to view a snapshot of the operations for the emis-
sion system on OBDII vehicles. I/M Monitors is a very
useful function. To guarantee no faults exist make sure
all monitors are ok or n/a and no DTC’s exist. Refer to
the vehicles service manual for the drive cycle operation.
During normal driving conditions, the vehicle computer
scans the emission system. After a specific amount of
drive time (each monitor has specific driving conditions
and time required), the computer monitors decide if the
vehicles emission system is working correctly or not as
well as detecting out of range values. When the monitor
status is:
• ok - vehicle was driven enough to complete the
monitor.
• inc (Incomplete) - vehicle was not driven enough to
complete the monitor.
• n/a (not applicable)- vehicle does not support that
monitor.
Depending on vehicle, disconnecting or a discharged
battery may erase DTCs and clear monitor status. Moni-
tors may be reset by:
• Erasing codes
• Vehicle control modules losing power
The I/M Monitors function can be run key on engine
running (KOER) or key on engine off (KOEO).
Extreme weather and/or road conditions can prevent a
monitor from running. Also, some monitors may require
a cold start to complete.

5.2 Read Codes
The Read Codes function allows the scan tool to read
the DTCs from the vehicle’s control modules. DTCs are
used to help determine the cause of a problem or prob-
lems with a vehicle. These codes cause the control
module to illuminate the malfunction indicator lamp
(MIL) when emission-related or driveability fault occurs.
When referring to the engine control module, MIL is also
known as service engine soon or check engine lamp.
Read Codes can be done with the key on engine off
(KOEO) or with the key on engine running (KOER).

describing the trouble code listed in the DTC number
field.
DTC Type - This area is reserved for providing additional
information about the DTC. Multiple DTC types may be
possible for a given DTC number. Not all vehicles sup-
port DTC types. This table describes possible DTC types.
DTC Type Description
History
Intermittent codes placed in the vehicle’s
memory when the trouble originally oc-
curred, and will remain there even if the
trouble has been corrected. If no trouble
after 50 engine warm-up cycles, the DTC
will be erased.
Confirmed
Confirmed codes are reported when a
component, sensor, or other part of the
vehicle is indication a malfunction is pres-
ent.
Current
Codes transmitted through the PCMs da-
ta stream when a trouble condition is ac-
tive and cannot be erased. The problem
must be repaired to remove the DTC.
Intermittent
Indicates the current code has been set
at least once but possibly not enough to
cause a history code to be stored.
MIL
Indicates that this DTC has turned on the
MIL light.
Pending
Pending codes are also referred to as
continuous monitor or maturing codes.
An intermittent fault causes the control
module to store a code in memory. If the
fault does not occur within a certain num-
ber of warm-up cycles (depending on ve-
hicle), the code clears from memory. If
fault occurs a specific number of times,
the code matures into a DTC and the MIL
illuminates or blinks. This function can be
used with KOEO or KOER.
Non-MIL
DTC that is not emission-related and did
not turn on the MIL light.
MIL Code
This DTC type also has a number with it
indicating that this is the code number
turning on the MIL. Vehicle service man-
uals may refer to this number instead of
the one listed in the DTC number field.
Permanent
Permanent codes are a special type of
confirmed code. Permanent codes be-
gan being reported by vehicles around
2010, and therefore not supported by ev-
ery vehicle. While Confirmed Codes can
be erased by the Tool, Permanent Codes
cannot. Permanent Codes are erased by
the vehicle when the vehicle has deter-
mined the fault is no longer present.
Active
DTC that was present at the time of scan
tool request.
Stored
DTC that was not present at the time of
scan tool request.

5.3 Erase Codes
The Erase Codes function deletes DTCs and resets I/M
Monitor data from vehicle’s control module(s). Perform
this function key on engine off (KOEO). Do not start the
engine.
The Erase Codes function may also erase View Freeze
Data, O2 Monitor Tests, and Diagnostic Monitor Test
results depending on vehicle.
The Erase Codes function sets monitors to inc.
Perform Erase Codes function only after systems have
been checked completely and DTCs have been written
down.
After servicing the vehicle, erase stored DTCs and verify
no codes have returned. If a DTC returns, problem has
not been fixed or other faults are present.
Depending on which monitor sets a code the vehicle
may need to be driven and the monitor ran before con-
cluding that the fault is repaired.

5.9 Drive Cycle Monitor
The Drive Cycle Monitor function is very similar to I/M
Monitors though the Drive Cycle Monitor is used to
view real-time operations of the emissions system on
OBDII vehicles. Drive Cycle Monitor continuously
updates as the vehicle reports operations of the emis-
sion system.
CAUTION
Two people must be in vehicle when driving.
One to drive and the other to operate the
scan tool.
• Refer to the vehicle service manual for the drive
cycle operation.
Drive Cycle Monitor can be used if you want to drive the
vehicle until all of the monitors are OK.
During normal driving conditions, the vehicle computer
scans the emission system. After a specific amount of
drive time (each monitor has specific driving conditions
and time requirements), the computer monitors will
decide if the vehicle emissions system is working cor-
rectly or not as well as detecting out a range of values.
When the monitor status is:
• “ok” - vehicle has been driven enough for function.
• “inc” (incomplete) - vehicle was not driven enough
to complete all of the monitors.
• “n/a” (not applicable) - vehicle does not support
that monitor.
Reset monitors by:
• Erasing codes.
• Vehicle computer module losing power (on some
vehicles).

Monitor Tests” in this section to see O2 monitor data.
• O2 sensors are located before (upstream) and after
(downstream) catalyst(s). Sensors are named (xy) for
their position to both cylinder banks and catalysts.
– The O2 sensor for cylinder bank 1 has prefix 1y
while O2 sensor for cylinder bank 2 has prefix 2y.
– The O2 sensor upstream of catalyst (closest to
engine) has suffix x1 while O2 sensor down-
stream of catalyst has suffix x2. If vehicle con-
tains more catalysts, O2 sensor downstream of
second catalyst has suffix x3 and O2 sensor
downstream of next catalyst has suffix x4.
– For example, O2S21 is upstream O2 sensor for
cylinder bank 2.

Test Results
DLC Cranking Voltage 8.0
DLC KOER Voltage 14.6
DLC KOEO Voltage 11.7
On the first “Test Results” screen example, the Scan
Tool did not detect that the engine had started. Because
of this, there is no KOER voltage reading.
The second “Test Results” screen example did detect
that the engine had started, and a KOER reading is
displayed.
The second “Test Results” screen example shows that
the KOEO voltage before an engine start was attempted
was 11.7V. Once the starter began cranking the engine,
a cranking voltage of 8V was measured. After the engine
started, a KOER voltage reading of 14.6V was measured.
• If the KOEO voltage is very low, this could be an
indication of a bad battery, or one that needs to be
charged.
• If the cranking voltage is a lot lower than the KOEO
voltage, than this is an indication of a worn starter.
• If the KOER voltage is not higher than the KOEO
voltage, than this indicates a bad or weak alternator.
7. After reviewing the test results, press or to
return to the Diagnostic Menu.
5.14 Vehicle Information
The Vehicle Information function allows the scan tool to
request the vehicle’s VIN number, calibration ID(s) which
identifies software version in vehicle control module(s),
calibration verification numbers (CVN(s)) and in-use
performance tracking.
• Vehicle Information function applies to model year
2000 and newer OBDII compliant vehicles.
• The scan tool cannot verify if data is correct for
scanned vehicles.
• CVNs are calculated values required by OBDII regula-
tions.
• The CVN calculation may take several minutes.
• CVNs are reported to determine if emission-related
calibrations have been changed. Multiple CVNs may
be reported for a control module.
• In-use performance tracking, tracks performance of
key I/M Monitors.

Open loop (OL):
A control system mode that does not monitor the output
to verify if the desired results were achieved. A fuel
delivery system usually operates in open loop mode
during cold engine warm-up because the oxygen sensors
are not yet ready to send a signal. Without the oxygen
sensor signal, the computer cannot check the actual
results of combustion.
PCM:

various actuators to control the engine. The PCM is also
known as the ECM (engine control module).
Pending codes:

simply an air door. Fuel is not added until the injectors
at each intake port are activated. In each case, the
throttle body is attached to the accelerator pedal.

brought about when the throttle is completely (or
nearly) open. The PCM typically delivers extra fuel to the
engine and de-energizs the A/C compressor at this time
for acceleration purposes. The PCM uses a switch or the
TPS to identify the WOT condition.
