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.

OBD Diagnostic Trouble Codes(DTCs)
Diagnostic Trouble Codes are how OBDII identifies and communicates to you with
the on board computer. When the computer recognizes and identifies a problem, a
DTC for the fault is stored in its memory. These codes are intended to help the user
to determine the root cause of the problem.
These OBDII DTC codes are made up of:
st
• The 1 character in the DTC indicates a letter which identifies the “main
system” where the fault occurred (Powertrain, Body, Chassis or Network)
nd
• The 2 character is a numerical digit which identifies “Generic or Manufacturer
Specific”
rd
• The 3 character is also a numerical digit which identifies the specific systems
or sub-systems where the problem is located.
th
th
• The 4 and 5 characters are also numerical digits which identifies the section
of the system that is malfunctioning.
Within each category (Power train, Chassis, Body and Network) of
DTCs there are assigned ranges for different vehicle systems.

2.5-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:
¾ The 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.
¾ Check the condition of air hoses and the air filter must be cleaned. Replace if
necessary.
¾ Make sure the timing belts are in good conditions and properly tensioned.
¾ Make sure the spark plugs are cleaned and in good condition. Check for loose,
damaged, disconnected or missing plug cables.
¾ Make 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.
¾ Check all electrical wirings and harnesses for proper connections and condition of
its insulation.
¾ Check all rubber hoses (radiator) and steel hoses (vacuum and fuel) for leaks,
cracks, blockage or other damages.
¾ Make sure the engine is mechanically sound. Do a compression check, engine
vacuum check, timing check, etc.
¾ Always refer to the manufacturer’s Service Manual
if you are not sure of the repair procedures.

2.8-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:
o
• Engine coolant temperature should exceed 70 C
o
• Engine coolant temperature should change more than 20 C after starting the
engine.
• Engine speed should go over 400 RPM.
st
When the powertain control module (PCM) detects a fault during the 1 trip, the DTC and
the corresponding ‘Freeze Frame’ data are stored in the PCM’s memory. The MIL will not
nd
light up until the fault is again detected during the 2 trip. Certain DTCs are capable of
turning the MIL on or blinking during the first trip.

Manufacturer controlled codes (non-uniform DTCs)
Areas within each alpha designator have been made available for
manufacturer-controlled DTCs. These are fault codes that will not generally be used
by a majority of the manufacturers due to basic system differences, implementation
differences, or diagnostic strategy differences. Each vehicle manufacturer or
supplier who designs and specifies diagnostic algorithms, software, and diagnostic
trouble codes are strongly encouraged to remain consistent across their product line
when assigning codes in the manufacturer controlled area. For powertrain codes,
the same groupings should be used as in the ISO /SAE controlled area, i.e. 100's
and 200's for fuel and air metering, 300's for ignition system or misfire, etc.
Code groupings for non-powertrain codes will be specified at a later date.
While each manufacturer has the ability to define the controlled DTCs to meet their
specific controller algorithms, all DTC words shall meet ISO 15031-2.

Appendix
4.1 Appendix A – PID Definitions
Global PID Definitions
All global parameter identification (PID) data listed were verified on actual
vehicles to guarantee accuracy. PID definitions were obtained from reliable
sources and are accurate at time of printing. It is possible that some newer
vehicles may contain data different from what is listed. Always refer to vehicle
service manual for manufacturer specific PIDs.
Remember; always refer the applicable service manual for detailed diagnostic
procedures when troubleshooting PID values.
Types of Data Parameters
INPUT:
These data parameters are obtained from sensor circuit
outputs. Sensor circuit outputs are inputs to the vehicles
PCM. For example, if oxygen sensor circuit was
generating a 400mV signal, then the code reader would
read O2S (v).40.
OUTPUT:
These data parameters are outputs or commands that
come directly from control module(s). For example, the
ignition spark advance is controlled by PCM, on most
vehicles, monitoring this PID shows spark output from
PCM.
CALCULATED These data parameters are calculated after analyzing
VALUE:
various inputs to the vehicles control module(s). For
example, the engine load. The PCM calculates this from
sensor inputs and displays in a percentage.
PCM VALUE:
Information that is stored in the control module(s) memory
and determined to be useful to service technician. An
example of this is TROUBLE CODE values, the DTC that
caused a freeze frame capture.
NOTE:
Several different causes can have the same parameter indication.
For information on diagnostics consult applicable service anuals.
NOTE:
The Scan Tool only displays the PID’s the vehicle supports.

4.5-Appendix E –What is EOBD,EOBD2 and OBD-II
What is EOBD?
EOBD is an abbreviation of European On-Board Diagnostics.
All petrol cars sold within Europe since 1 Jan 2001, and diesel cars manufactured
from 2003, must have on-board diagnostic systems to monitor engine emissions.
These systems were introduced in line with European Directive 98/69/EC to
monitor and reduce emissions from cars.
All such cars must also have a standard EOBD diagnostic socket that provides
access to this system (as shown below).
For information on the pins used within the port˖
The EOBD / ODBII 16-pin diagnostic connector (DLC)
Where is the connector?
The EOBD connector is required by the Directive to be located within the
passenger compartment of the car, within reach of the driver's seat. Tools
should not be required to reveal the connector, but it may have a
removeable cover over it.

Ͳ86Ͳ
What does the connector look like?
The connector has the following shape:
Which pins contacts should be present on the connector?
Different pins on the connector are used by different manufacturers. There
are 5 pinout combinations within the standard, each of which uses a
specific communications protocol. These are listed below:
Protocol
J1850 VPW
ISO 9141-2
J1850 PWM
KWP2000
(ISO 14230)
CAN (Controller
Area Network)
Connector pins used
2, 4, 5, and 16, but not 10

2, 4, 5, 10 and 16
4, 5, 7, 15 (see below) and 16

Note: For ISO/KWP2000 communications, pin 15 (L-line) is not always
required. Pin 15 was used on earlier ISO/KWP2000 cars to "wake-up" the
ECU before communication could begin on pin 7 (K-Line). Later cars tend
to communicate using only pin 7 (K-Line).
Rover and MG cars: We have noticed that many Rover and MG models
do not have pin 5 (Signal Ground). This can prevent some diagnostic tools
from 'powering up' where they use pin 5 as the ground for the circuitry.
What are each of the pins used for?
The pins are used as follows:

2
4
5

Only the latest scan tools and code readers can be relied upon to read the
diagnostic information through the EOBD socket.
'Check Engine' light
The 'Check Engine' warning light on the dashboard is often the first an owner
knows about a problem with their car.
This provides very little information to the owner, or to the garage asked to
investigate the problem.
Problem diagnosis
With the modern tools, skilled technicians should be able to diagnose and solve
many of the problems, which prior to this, required the sophisticated console tools
of main dealers.
New technology
The introduction of European on-board diagnostics standards has opened up new
opportunities for car garages and owners.
A range of low-cost tools are now available to read and clear error codes, to view
live/stored readings from sensors within the car, and to switch off the 'Check
Engine' light.
What information is available?
EOBD systems monitor and store information from sensors throughout the car,
e.g. air flow sensors and oxygen sensors.
|SCANͲDIYCRͲProWorkOnOBDͲII/EOBDͲII/CANBUSProtocolVehicle Ͳ89Ͳ
SCANͲDIYCRͲPROUser’sManual
Sensor values outside an acceptable range trigger a Diagnostic Trouble Code
(DTC). The Scan tools can help you read and interpret these codes, and view the
live sensor output.
EOBD or OBD II?
On-Board Diagnostics, or OBD, was the name given to the early emission control
and engine-management systems introduced in cars. There is no single OBD
standard - each manufacturer often using quite different systems (even between
individual car models).
OBD systems have been developed and enhanced, in line with United States
government requirements, into the current OBD II standard.
The OBD II Federal requirements apply to cars sold in the United States from
1996.
EOBD is the European equivalent of the American OBD II standard, which applies
to petrol cars sold in Europe from 2001 (and diesel cars 3 years later).
Why do OBDII and EOBD tools not work on all cars from 1996 in the
UK and Europe?
Some of our most frequently asked questions on our OBDII and EOBD
tools are:
"I have seen these/similar products advertised as working on all 1996
and newer cars - why don't yours?"
"I've just bought an OBDII/EOBD tool from someone else that was
advertised as working with all 1996 and newer cars.
Why doesn't it work on my [1999 Vauxhall Vectra]?"
Here is the answer...
In 1996 in the United States, a Federal Law came into force requiring all
US-sold cars to be OBDII compliant. Most OBDII tools are therefore
advertised as working with all cars from 1996.
The OBDII Federal Law applied only to cars sold in the US.
In the UK and the rest of Europe, our equivalent law (European On-Board
Diagnostics, or EOBD) did not come into force, and more importantly, was
not fully implemented by our car manufacturers, until 2001 for petrol cars
|SCANͲDIYCRͲProWorkOnOBDͲII/EOBDͲII/CANBUSProtocolVehicle SCANͲDIYCRͲPROUser’sManual

(2003/4 for diesels).
Where an OBDII tool is sold in the UK/Europe claiming to work on all cars
from 1996, this is highly unlikely to be the case.
Even where a seemingly identical car may have been sold in Europe and
the US before 2001, from our own testing and research, it is rarely the
case that the European model will be OBDII/EOBD compliant.
The fact that we sell these tools as only working with 2001 and newer
petrols (and similarly 2003/4 diesels) is due to the fact that we are being
honest in the coverage, rather than simply duplicating the sales
information from the US.
So do these tools work with any UK/European cars before 2001?
Yes they do, but certainly not across the board, and very rarely back as
far as 1996. A few manufacturers that we know have some OBDII/EOBD
support (on petrol models) before 2001 are listed below:
Ford (most petrol cars using the EEC-V engine management system)
Jaguar (most models from the beginning of the X300 series)
Volvo (some models)
A few examples of manufacturers that we have had very little success
connecting OBDII/EOBD tools on pre-2001 models are:
Vauxhall
Peugeot
Citroen
Fiat
Please be aware that we do not try to sell these tools as something they
are not.
What is EOBD2?
EOBD2 is not a new version of EOBD.
Where EOBD stands for 'European On-Board Diagnostics', EOBD2 actually
stands for 'Enhanced On-Board Diagnostics, Second Generation'.
EOBD2 tends to refer to manufacturer-specific features available on some
OBDII/EOBD tools to access additional parameters/information from a car, over
|SCANͲDIYCRͲProWorkOnOBDͲII/EOBDͲII/CANBUSProtocolVehicle Ͳ91Ͳ
SCANͲDIYCRͲPROUser’sManual
and above the normal parameters and information available within the
EOBD/OBDII standard.
EOBD2 features are normally highly manufacturer-specific, and will usually only
be available for a certain car manufacturer, e.g. Ford.
There are, as such, no 'EOBD2 cars', i.e. cars that require an EOBD2 tool to
access their diagnostics information. EOBD2 functionality might however allow
more information to be extracted from an EOBD/OBDII compliant car.
