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.
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 PARK (for automatic transmission) or
NEUTRAL (for manual transmission) 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. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called 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 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
that a technician can accurately find and fix the problem. Here below
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 Oil/Service Reset
The Engine Oil Life System calculates when to change the engine oil
and filter based on vehicle use. An oil change is required whenever
indicated by the display and according to the recommended
maintenance schedule. Whenever the oil is changed, reset the system
so it can calculate when the next oil change is required. If a situation
occurs where the oil is changed prior to a service indicator being
turned on, also reset the system.
2.3 EPB
3
The EPB is a system which controls the brake force by pulling the
parking cable as in conventional existing parking brakes. EPB
system includes a DC motor, a gearbox, a screw, a nut, a current
sensor, a Hall-effect force sensor, an acceleration sensor and an
ECU.
Generally, if a driver or a high level system operates the EPB system,
the controller calculates a target force from the parking cable based
on the car mass as well as the inclination of the road as measured by
the acceleration sensor. The EPB increases the brake force by pulling
the parking cable using the DC motor until the brake force reaches
the target force. Brake force is measured by the Hall-effect force
sensor.
2.4 TPMS system review
A tire pressure monitoring system (TPMS) is an electronic system
designed to monitor the air pressure inside the pneumatic tires on
various types of vehicles. TPMS report real-time tire-pressure
information to the driver of the vehicle, either via a gauge, a
pictogram display, or a simple low-pressure warning light. TPMS
can be divided into two different types — direct (dTPMS) and
indirect (iTPMS). TPMS are provided both at an OEM (factory)
level as well as an aftermarket solution.
When diagnosing TPMS systems, you should understand what the
TPMS tell-tale light means.
When turning the ignition OFF to ON, the TPMS tell-tale should
come on, and then go off, which indicates the system is working fine.
If the light stays on, there would be a pressure problem. If the light
flashes, there would be a system problem, which can range from
faulty sensors to sensors on the vehicle that haven‘t been learned to
that vehicle.
2.5 ABS and SRS systems
ABS -“Anti-lock Braking System” in most vehicles is made up of
an electronic hydraulic pump of two, three or most commonly four
Wheel Speed Sensors (WSS), a G-force sensor, a Vehicle Speed
Sensor and an ABS Control Module (EBCM). The EBCM is
4
constantly monitoring the WSS, the Vehicle Speed Sensor, and the
G-sensor.
Diagnosing an ABS problem should always start with a visual
inspection of all brake components, then you will need to retrieve
ABS DTCs to tell you where the problem is.
SRS - “Supplemental Restraint System” is made up of Impact
Sensors, a Control Module, and Airbags. When the impact sensors
detect a collision they send an extremely fast signal to the control
module, which relays that signal to the airbags, deploying them to
help prevent vehicle occupants from hitting interior objects such as
steering wheels, dashboards, and the like. When the control module
detects a problem with the airbags or sensors the Malfunction
Indicator Light (MIL) will turn on。
2.6 SAS review
SAS, steering angle sensor, measures the rotation angle, angle
velocity and direction of the steering wheel, providing information on
the direction in which the driver wishes to go. Steering angle sensors
are required for systems such as ESC and are also used in electric
power steering and active steering systems (EPS or AFS) as well as
parking assistance systems and curve lights.
A scan tool can be used to obtain this data in degrees. The SAS is
located in a sensor cluster in the steering column. The cluster always
has more than one steering position sensor for redundancy and to
confirm data. The ESC module must receive two signals to confirm
the steering wheel position. These signals are often out of phase with
each other.
Many vehicles require the SAS be reset or recalibrated after an
alignment is performed or parts in the steering system are replaced。
There are three types of reset procedures, systems that self calibrate
on their own, vehicles that require specific wires or buttons be
pressed and, systems that require recalibration with a scan tool.
5
Self-Calibration
Some newer vehicles can auto calibrate by having the wheel turned
from lock to lock and then centered and cycling the key。
Scan Tool Steering Angle Sensor Reset
There are many options for scan tools to reset SASs. Some tools are
even integrated into an alignment system. But, most tools recommend
that the calibration be performed on a level surface. Also, it is a good
idea to perform a lock-to-lock turn to complete the calibration.
2.7 DPF review
A Diesel Particulate Filter, often referred to as the DPF is a device
designed and integrated into the Diesel Engine exhaust systems to
trap and remove Diesel Particulate Matter or Soot from the exhaust
gasses of the diesel engine. A DPF works in conjunction with the
oxidation catalyst and EGR valve to remove a majority of the NOx,
particulate matter and unburned hydrocarbons from burned diesel fuel.
The result of DPF is greater economy, improved smoothness and a
reduction of harmful emissions.
The soot trapped in DPF will partially block your DPF causing the
DPF/CAT light to illuminate on the dash (normally when 45%
blockage is reached) at which point regeneration is required to get the
DPF back in to safety zone.
DPF light on
When the DPF light appear on the dash intermittently, this means
there is a partial blockage in your DPF and a regeneration process is
required. If you ignore it and keep on driving, eventually it will stay
on permanently and in most severe cases brings on the Engine
management light and even the Coil Light. If this happens, you will
lose all power and vehicle will fall into ―Limp Mode‖.
Regeneration process
6
Regeneration is the DPF‘s way to clear the blockage through
continuously burning it at higher temperatures and allowing the now
harmless produce to escape through the exhaust system. There are
two types of regeneration processes for vehicles.
Passive regeneration
Passive regeneration is an automated regeneration which often occurs
on drives where there is prolonged high exhaust temperatures, for
example, on motorway-type runs. This needs no intervention from the
engine control unit. ECM monitors driving style and selects a suitable
time to employ regeneration. Regeneration continues until ECM
calculates that all the soot has been burned. But sometimes the
required long journey motorway-type trip necessary to complete a
passive regeneration of the DPF system is not attained, the
regeneration fails. So manufacturers have had to adapt the technology
and design an ―active‖ regeneration process controlled by the ECM.
Active regeneration
When the diesel particulate (soot) loading in the DPF reaches a
pre-set limit (normally around 45%), the ECU will make minor
adjustments to the fuel injection timing system which will in turn
increase the exhaust temperatures and help initiate the DPF
regeneration process. This is a smart way of getting a motorway-type
temperature to build up inside the DPF system and begin a full
regeneration to bring the unit back to good health.

5. OBDII Diagnostics
The OBD II Diagnostics function is a fast-access option that allows
you to carry out a quick test on the engine system of OBD II
vehicles.
When more than one vehicle control module is detected by the
scan tool, you will be prompted to select the module where the
data may be retrieved. The most often to be selected are the
Power train Control Module [PCM] and Transmission Control
Module [TCM].
CAUTION: Don’t connect or disconnect any test equipment with
ignition on or engine running.
1） Turn the ignition off.
2） Locate the vehicle‘s 16-pin Data Link Connector (DLC).
3） Plug the scan tool cable connector into the vehicle‘s DLC.
4） Turn the ignition on. Engine can be off or running.
5） Turn on the scan tool. Select OBDII from the Main Screen.
(Figure 3.1)
6） Press the OK button to wait for the Menu to appear. A sequence
of messages displaying the OBDII protocols will be observed
on the display until the vehicle protocol is detected.
If the scan tool fails to communicate with the vehicle’s ECU
(Engine Control Unit) more than three times, a “LINKING
ERROR!” message shows up on the display.
Verify that the ignition is ON.
Check if the scan tool‘s OBD II connector is securely
connected to the vehicle‘s DLC.
Verify that the vehicle is OBD2 compliant.
Turn the ignition off and wait for about 10 seconds. Turn the
ignition back to on and repeat the procedure from step 5.
If the “LINKING ERROR” message does not go away, then
there might be problems for the scan tool to communicate
20
with the vehicle. Contact your local distributor or the
manufacturer’s customer service department for assistance.
7） View a summary of system status (MIL status, DTC counts,
Monitor status) on screen. (Figure 5.1 ) Press ESC button for
Diagnostic Menu (Figure 5.3) to come up.
Figure 5.1
If more than one module is detected, you will be prompted to
select a module before testing. (Figure 5.2 )
Use the UP/DOWN scroll button to select a module and press
the OK button.
5.1. Read Codes
Reading Codes can be done with the key on engine off (KOEO)
or with the key on engine running (KOER).
Figure 5.2
21
Stored Codes are also known as “hard codes”, which are fault
codes, or trouble codes that have been stored in the vehicle
computer memory because the faults have reoccurred for
more than a specified amount of key-cycles. These codes will
cause the control module to illuminate the malfunction
indicator light (MIL) when emission-related fault occurs.
Pending Codes 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 lamp (MIL). If the fault
does not occur within a certain number of warm-up cycles, the
code clears from memory.
Permanent Codes are DTCs that are "confirmed" and are
retained in the non-volatile memory of the computer until the
appropriate monitor for each DTC has determined that the
malfunction is no longer present and is not commanding the
MIL on. Permanent DTC shall be stored in non-volatile
memory and may not be erased by any diagnostic services or
by disconnecting power to ECU.
1) Use UP/DOWN scroll button to select Read Codes from
Diagnostic Menu and press OK button. (Figure 5.3 )
Figure 5.3
2) Use the UP/DOWN scroll button to select Stored Codes or
Pending Codes from the Read Codes menu and press the OK
button. (Figure 5.4 )
22
Figure 5.4
If there is not any Diagnostic Trouble Code, the display indicates
―No (pending) codes are stored in the module!‖ Wait a few
