What is EOBD?
The American Environmental Protection Agency and the European government
have set targets for reducing the levels of pollution produced by passenger and
commercial vehicles. In order to ensure that these targets can be met,
manufacturers are required to build new vehicles which meet increasingly stiff
emissions standards. The manufacturers must further maintain these emission
standards for the useful life of the vehicle. In order to meet and maintain these
standards the vehicles are fitted with On-Board Diagnostic systems which monitor
the integrity and effectiveness of all emission related components.
As vehicles are becoming more and more complex, many of the systems fitted to
them are being controlled by electronic control modules. Most vehicles now have
multiple control modules (e.g. Engine, Transmission, Body, Suspension, etc.)
located at different locations on the vehicle. The On-Board Diagnostic systems are
integrated into the vehicle control modules.
With so many different vehicle and component manufacturers, a common interface
was required to communicate with these control modules. In 1988, the SAE
(Society of Automotive Engineers) created a standard that defined a standard
diagnostic socket (J1962) and a set of diagnostic test signals.
With the diagnostic socket and diagnostic signals agreed, another standard was
produced that defined a universal inspection and diagnosis method to ensure that a
vehicle is performing to Original Equipment Manufacturer (OEM) specifications.
This standard is known as EOBD (European On-Board Diagnostics).
The fundamental requirement for an EOBD system is that in the event of an
emissions related component fault, a DTC (Diagnostic Trouble Code) will be stored
in the memory of the control module responsible for that component, and a
Malfunction Indicator Lamp (MIL) will illuminate on the vehicle's instrument pack to
alert the driver. The DTC can then be retrieved using diagnostic equipment to
determine the type and status of the fault.

Identifying compliant vehicles
All petrol engine vehicles manufactured since 2000 should be EOBD compliant.
Some manufacturers began incorporating On-Board Diagnostic systems as early as
1994, however not all are 100% compliant. All diesel engine vehicles are expected
to have support from 2004. This means that diagnostic information, related to
vehicle emissions, may be extracted from the vehicle via the J1962 diagnostic
socket using the service tool.
The service tool can communicate with any EOBD compliant vehicle using one of
the five diagnostic communication protocols defined in the standard.
These are
ISO 9141.
Keyword 2000 (originally a European protocol).
J1850 PWM (pulse width modulated) protocol used by Ford.
J1850 VPW (variable pulse width modulated) used by General Motors in USA
designed vehicles.
CAN (controller area network) currently being legislated for and likely to be a
principle diagnostic communication system in the future. A European protocol.
It is normally possible to tell which is used on a specific vehicle by examining the
diagnostic socket (as below), however the service tool's software will automatically
detect the protocol used on the vehicle to which it is connected.
NOTE: Although there are different EOBD electrical connection protocols, the
command set is fixed according to the SAE J1979 standard.
If the diagnostic socket has a pin in the '7' or
'15' position, then the vehicle uses either the
ISO 9141 or Keyword 2000 protocol.
If the diagnostic socket has a pin in the '2' or
'10' position, then the vehicle uses one of the
SAE J1850 protocols.
If the diagnostic socket has a pin in the '6' or
'14' position, then the vehicle uses the CAN
protocol.

Diagnostic Trouble Codes
Diagnostic Trouble Codes (DTCs) are divided into mandatory and voluntary codes.
Mandatory codes are allocated by the ISO (International Standards Organisation) /
SAE (Society of Automotive Engineers). Voluntary codes are allocated by various
vehicle manufacturers and are manufacturer specific and in some instances, vehicle
specific.
ISO/SAE controlled diagnostic trouble codes are those codes where industry
uniformity has been achieved. These codes were felt to be common enough across
most manufacturer's applications that a common number and fault message could
be assigned. All unspecified numbers in each grouping have been reserved for
future growth. Although service procedures may differ widely amongst
manufacturers, the fault being indicated is common enough to be assigned a
particular fault code. Codes in this area are not to be used by manufacturers until
they have been approved by ISO/SAE.
Areas within each of the fault code blocks have been allocated for manufacturer
controlled DTCs. These are fault codes that will not generally be used by the
majority of the manufacturers due to basic system differences, implementation
differences, or diagnostic strategy differences.

Interpreting EOBD fault codes
Use the following rules to determine the basic meaning of an EOBD fault code.
The first character indicates which area of the vehicle the code applies to.
The second character specifies the type of code:
If the first character was 'P' (Powertrain) then the third character identifies the
specific Powertrain system concerned:
The last two characters identify the specific fault as seen by the on-board systems.
P Powertrain
B Body
CChassis
UNetwork
0 Standard (SAE) code
1 Manufacturer's own code
1 Fuel and air metering
2 Fuel and air metering, specifically injector circuit
3 Ignition system and misfire detection
4 Auxiliary emission controls
