2. OBD (On-Board Diagnostics) II Introduction
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
Figure 1-1-2 Product Display
Figure 1-1-5 Main Screen Interface
3

"OBDII".
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 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 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 12 inches 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 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. OBD-II Diagnosis
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.
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 or into the vehicle's DLC.
1. Turn the ignition on. Engine can be off or running.
2. Turn on the scan tool. Select OBDII from the Main Screen.
3. 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.
3.1 Read DTCs (Diagnostic Trouble Codes)
OBD II 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
5

problem area and are intended to provide you with a guide as to
where a fault might be occurring within a vehicle.
There are three types of DTCs:
1. Stored DTCs - A DTC is stored when a fault condition has
occurred that meets enough criteria to activate the MIL.
2. Pending DTCs - When a fault condition is identied during a Drive
Cycle, but does not meet enough criteria to activate the MIL. If the
fault condition occurs during two consecutive Drive Cycles, it will turn
into a Stored DTC and the MIL will activate.
3. Permanent DTCs - A stored DTC that can only be cleared by the
OBDII system, after repairs are made, and a set number of Driving
Cycles have been completed.
OBD II Diagnostic Trouble Codes consists of a five-digit alphanu-
meric 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:
DTC Example:
P 0 2 0 2
P--Systems: B=Body C= Chassis P=Powertrain U=Network
0--Code Type Generic(SAE): P0, P2, P34-P39; B0, B3; C0, C3;U0, U3
(Manufacturer Specific: P1, P30-P33; B1, B2; C1, C2; U1,U2)

3.5 I/M Readiness Monitors
An important part of a vehicle's OBD II 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) defined by the U.S. Environmental Protection Agency(EPA).
Not all monitors are supported by all vehicles and the exact number
of monitors in any vehicle depends on the motor vehicle manufac-
turer's emissions control strategy.
Figure 3-4-1 Freeze Frame
Interface
12

In order for the OBD monitor system to become ready, the vehicle
should be driven under a 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 vehicles OBD monitor
system ready, please consult your vehicle owner's manual.
I/M Readiness function is used to check the operations of the
Emission System on OBD2 compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected for compliance to
a state emissions program.
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 memory. Times for reset vary
depending on vehicle.
Some latest vehicle models may support two types of I/M
Readiness tests:
1. Since DTCs Cleared - indicates status of the monitors since the
DTCs are erased.
2. This Drive Cycle - indicates status of monitors since the
beginning of the current drive cycle.
