2. General Information

2.1 On-Board Diagnostics（OBD）II

The first generation of On-Board Diagnostics(calle 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 eigher 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 follow

three pices 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 Diagnostic Trouble Codes (DTCs)

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 problem area and

are intended to provide you with a guide as to where a fault might

be occurring within a vehicle. OBD II Diagnostic Trouble Codes

consists of a five-digit alphanumeric 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:

2

.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 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 behine 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

2.4 OBD II 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 in any vehicle depends on the motor vehicle manufacturer’s

emissions control stragtegy。

Continuous Monitors – Some of the vehicle components or systems are

continuously tested by the vehicle’s OBD II system，while others are tested

only under specific vehicle operating conditions。The continuously monitored

components listed below are always ready:

1) Misfire

2) Fuel System

3) Comprehensive Components(CCM)

Once the vehicle is running ，the OBD II system is continuously checking

the above components，monitoring key engine sensors，watching for engine

misfire，and monitoring fuel demands。

Non-Continuous Monitors –Unlike the continuous monitors，many

emissions and engine system components require the vehicle to be operated

under specific conditions before the monitor is read。These monitors are

termed non-continuous monitors。For different ignition type engines，the

available monitors are different too。

4

The following monitors are to be used for spark ignition (Gasoling) engines

only:

1) EGR System

2) O2 Sensors

3) Catalyst

4) Evaporative System

5) O2 Sensor Heater

6) Secondary air

7) Heated Catalyst

The following monitors are to be used for compression ignition (Diesel)

engines only:

1）

EGR System

2）

NMHC Catalyst

3）

NOx aftertreatment

4）

Boost pressure system

5）

Exhaust gas sensor

6）

PM filter

2.5 OBD II Monitor Readiness Status

OBD II systems must indicate whether or not the vehicle’s PCM’s monitor

system has completed testing on each component。Components that have

heen tested will be reported as “Ready”，or “Complete”，meaning they have

been tested by the OBD II system。The purpose of recording readiness status

is to allow inspectors to determine if the vehicle’s OBD II 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 OBD monitor system to become ready，the vehicle should be

driven under 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 vehicle’s OBD monitor system ready，please consult your

vehicle owner’s manual。

2.6 OBD II Definitions

Power-train Control Module (PCM) – OBD II terminology for the on-board

Computer that controls engine and drive train。

Malfunction Indicator Light (MIL) – Malfunction Indicator Light (Service

Engine Soon，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 federal standards。If the MIL illuminates with a steady light，it

indicates that a problem has been detected and the vehicle should be serviced

as soon as possible。Under certain conditions，the dashboard light will blink

or flash。This indicates a severe problem and flashing is intended to

discourage vehicle operation。The vehicle onboard diagnostic system can not

turn the MIL off necessary reairs 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-specific events or conditions that must occur

within the engine before

the various monitors will set，or run。Some monitors require the various 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。

OBD II Drive Cycle – A specific mode of vehicle operation that

provides conditions required set all the readiness monitors completing and

OBD II drive cycle is to force the vehicle to run its onboard diagnostics。

Some 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 specific

drive cycle，consult the vehicle’s

Owner’s Manual。

Freeze Frame Data –

When an emissions related fault occurs，the OBD

II 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

parmeters such as engine RPM，vehicle speed，air flow，engine load，fuel

pressure，fuel trim value，engine coolant temperature，ignition timing

advance，or closed loop status。

6

2.7 OBD II Modes of Operation

Here is a basic introduction to the OBD II communication protocol。

Mode byte : The first byte in the stream is the mode number。There are 10

modes for diagnostic requests。The first byte in the response data bytes is this

same number plus 64。For example，a mode 1 request would have the first

data byte =1，and the response would have the first data byte=65。Here is a

brief description of the modes :

Mode $01 – Identifies the Powertrain information and shows current

data available to the scan tool。

This data includes: DTC set，status of

on-board tests，and vehicle data such as engine RPM，temperatures，ignition

advance，speed，air flow 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 fit in the data

bytes of the response message，or it there are more than one ECU 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-Rich 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.

7

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 defined by a given

vehicle maker 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 fixed 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 specific。

Mode $09 – Reports vehicle information. This information includes vehicle

VIN number and calibration information stored in the vehicle ECUs。

Mode $0A – Request Emission-Related Diagnostic Throuble Code with

Permanent Status. This presence of permanent DTCs at an inspection

without the MIL illuminated is an indication that a proper repair was not

verified by the on-board monitoring system。

3.8 Vehicle Coverage

The scan tool is specially designed to work with all OBD II compliant

vehicles，including control area network (CAN)，it is required by EPA

that all 1996 and newer vehicles (Cars and light trucks) sold in the

united states must be OBD II compliant and this includes all american，

asian and European vehicles。

A small number of 1994 and 1995 model year gasoline vehicles are OBD

II compliant。To verify if a 1994 or 1995 vehicle is OBD II compliant，

check the vehicle emissions control information(VECI) Label，which is

located under the hood or by the radiator of most vehicles。If the vehicle

is OBD II compliant，the label will designate “OBD II Certified”。

Additionally ， Government regulations mandate that all OBD II

compliant vehicles must have a “common” sixteen-pin Data Link

Connector (DLC)。

For the vehicle to be OBD II compliant is must

have a 16-pin DLC (Data

Link Connector) under the dash and the vehicle emission control

information label must state that the vehicle is OBD II compliant。

4. OPERATION
