ISO (International Organization for Standardization) is the world‘s largest developer and publisher of International Standards.
ISO is a network of the national standards institutes of 163 countries, one member per country,
with a Central Secretariat in Geneva, Switzerland, that coordinates the
system (source www.iso.org)
Following standards (relevant for
diagnostics) were published by ISO:
- ISO 9141 CARB requirements for intervhange of digital information
- ISO
14230-1/2/3/4 KeyWord Protocol 2000 (Physical Layer / K-Line, Data Link Layer /
Transport Protocol, Application Layer / Services and OBD)

SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries.
SAE International‘s core competencies are life-long learning and voluntary consensus standards development.
SAE International‘s charitable arm is the SAE Foundation, which supports many
programs, including A World In Motion? and the Collegiate Design Series (source
www.sae.org).
Following standards (relevant for diagnostics) were
published by SAE:
- SAE J2434-1/2 Pass Thru (standard vehicle interface for
reprogramming, optional feature)
Basically the diagnostic communication is an serial data exchange between the so called client (tester) and server (ECU – electronic control unit).
Currently standardized interfaces on the OBD connector are:
- K-Line (ISO 14230), up to 128 kBd (typical 9600 or 10400 Bd)
-
CAN (ISO 11898), up to 1 MBd (typical 50/100 kBd for low speed and 500 kBd for
high speed)
- Ethernet (ISO 14300, next generation of vehicle access, up to
1Gbit, typical 10 Mbit)
Main objective of a protocol is the definition of timing parameters, requests and responses to read and write data (commands),
where the execution of commands is done in order to so called sessions and sessions were activated by security access level using seed&key mechanism.
Typical r/w commands are: session handling, identification data, variant
coding, update programming, fault memory, sensor test etc.
Basically there are three types of standardized diagnostic
communication protocols:
- OBD (ISO 15301-5 and ISO 14230-4),
Modes used on K-Line and CAN
-
KWP2000 (ISO 14230-3), Services are used on K-Line and CAN
- UDS (ISO 14229-1), Services are used on CAN and
Ethernet
CAN physical layer standards
There are several CAN physical layer standards:
? ISO 11898-1: CAN
Data Link Layer and Physical Signaling
? ISO 11898-2: CAN High-Speed Medium
Access Unit
? ISO 11898-3: CAN Low-Speed, Fault-Tolerant, Medium-Dependent
Interface
? ISO 11898-4: CAN
Time-Triggered Communication
? ISO 11898-5: CAN High-Speed
Medium Access Unit with Low-Power Mode
? ISO 11898-6: CAN High-speed
medium access unit with selective wake-up functionality
? ISO 11992-1: CAN fault-tolerant for truck/trailer communication
? ISO 11783-2: 250 kbit/s, Agricultural Standard
? SAE J1939-11: 250 kbit/s, Shielded Twisted Pair (STP)
? SAE J1939-15:
250 kbit/s, Unshielded Twisted Pair (UTP) (reduced layer)
? SAE J2411: Single-wire CAN (SWC)
The diagnostic interfaces provide a communication link between OBD system
and external test equipment.
There are three physical diagnostic interfaces:
1) SAE J1850 (ISO 11519-4) – Class B data communication interface:
two alternative physical implementations:
single-wired 10.4 kbit/s VPW (Variable Pulse Width) and two-wired differential 41.6 kbit/s PWM (Pulse Width Modulation).
Application: mainly GM and Ford.
2) ISO 9141-2 / ISO 14230 – K-line
interface:
10.4 kbit/s, single-wired interface, compatible with UART/SCI byte/word interface.
The optional L-line is used only during initialization.
Application: most European and Asian manufacturers, also Chrysler and GM.
3) ISO 15765-4 (ISO 11898) – CAN
interface:
high speed two-wired differential interface, 500 kbit/s.
Application: will be mandatory after model year 2008.
