Introduction to On-Board Diagnostics OBD II
On-board diagnostics version II (OBD II) 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 OBD II compliant.
 Technicians can now use the same tool to test any OBD II
compliant vehicle without special adapters. SAE established
guidelines that provide:
 A universal 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 conditions
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.
SAE Publications
SAE has published hundreds of pages of text defining a standard
communication protocol that establishes hardware, software, and
circuit parameters of OBD II systems.
• 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.

Display Functions:
①Diagnostic Trouble Codes Display Area.
When the DTC reader found a fault code in the
PCM, it will display here. Each fault is assigned
a code number that is specific to the fault.
②PENDING Icon：
Indicates the currently display DTC is a
“Pending” Code.
③DTC Definitions：
Information on DTC definitions, Freeze Frame
data and test messages are displayed here.
④DTC Number Sequence：
The DTC reader assigns a code sequence number to each DTC found in the
vehicle’s PCM. The sequence will start from 1. This number will indicate which
code is currently displayed. / DTC Enumerator Indicates the total number of
codes retrieved from the vehicle’s ECU.
⑤G/E instruction:
Generic DTC / Enhanced DTC
⑥Link Icon：
Indicates whether that the DTC Reader is communicating
with the vehicle’s computer or not.
⑦LED instruction:

Getting Started:
Before you use Scan Tool on the vehicle, please ensure that mechanical problems such
as low oil level, damaged hoses, wiring or electrical connections are fixed FIRST. They
may cause a fault code to set.
The following Areas need to be checked before starting any test:
¾The levels of engine oil, power steering fluid, transmission fluid (if auto
transmission), engine coolant and other fluids must be at proper level. Top up if
necessary.
¾Check the condition of air hoses and the air filter must be cleaned. Replace if
necessary.
¾Make sure the timing belts are in good condition and properly tensioned.
¾Make sure the spark plugs are cleaned and in good condition. Check for loose,
damaged, disconnected or missing plug cables.
¾Make sure that all mechanical linkages to the engine sensors (throttle, gearshift
position, transmission, etc) are secure and properly connected. Refer to Service
Manuals for locations.
¾Check all electrical wirings and harnesses for proper connections and condition of
its insulation.
¾Check all rubber hoses (radiator) and steel hoses (vacuum and fuel) for leaks,
cracks, blockage or other damages.
¾Make sure the engine is mechanically sound. Do a compression check, engine
vacuum check, timing check, etc.
¾Always refer to the manufacturer’s Service Manual
if you are not sure of the repair procedures.

Malfunction Indicator Lamp (MIL):
When the vehicle on board computer detects a problem in the emission related
systems or components, its diagnostic program will assign a fault code (DTC) and
store it in its memory. It also records a “Freeze Frame” of the conditions present
when the fault was found and set the malfunction indicator lamp (MIL) alight. Some
faults require detection
for two trips in a row before the MIL is turned on.
Three typical examples of MIL are shown below:
Definition of Trip
‘A Trip’ is define as a Key-ON, Key-OFF event in which the powertrain control
module (PCM) detects the following:
• Engine coolant temperature should exceed 70oC
• Engine coolant temperature should change more than 20oC after starting the
engine.
• Engine speed should go over 400 RPM.
When the powertain control module (PCM) detects a fault during the 1st trip, the DTC
and the corresponding ‘Freeze Frame’ data are stored in the PCM’s memory. The
MIL will not light up until the fault is again detected during the 2nd trip. Certain DTCs
are
capable of turning the MIL on or blinking during the first trip.

Vehicle Diagnostic
When everything had been confirmed and checked as mentioned in Getting Started, the
testing operation can be carried out.
1. Locate the vehicle Diagnostic
Link Connector (DLC) and
make sure that the ignition
switch is in OFF position.
2. Connect the Scan Tool cable
connector to the vehicle’s DLC.
• If problem of connecting,
rotate it to 180o and try again.
3. When the connection has been established, Press button,
the Scan tool will light up and it will display as below:

4. After a few seconds, it will switch to:
5. If the vehicle Diagnostic Protocol is
OBD-II，But the DTC Code is
MANUFACTORY，Please press UP or
DN button，then press yes , the screen
will change to:
Or else, Press NO,forget this step and
Select MF
6．Turn the ignition on.
DO NOT start the engine.
7．Press the button once, the
Scan tool will automatically start to
communicate the ECU of vehicle
and search which type of
communication protocol is using.
Once the Scan tool identifies the
computer’s communications
protocol, a communication link is
established.
The protocol type will be shown on
the LCD display.
