SAE standards documents on OBD-II
- J1708 - Defines a standard used for serial communications between ECUs on a heavy duty vehicle and also between a computer and the vehicle.
- J1850 - Defines a serial data protocol. There are two variants- 10.4 kbit/s (single wire, VPW) and 41.6 kbit/s (two wire, PWM). Mainly used by US manufacturers, also known as PCI (Chrysler, 10.4 kbit/s), Class 2 (GM, 10.4 kbit/s), and SCP (Ford, 41.6 kbit/s)
- J1939 - Defines a data protocol for heavy duty commercial vehicles
- J1962 - Defines the physical connector used for the OBD-II interface.
- J1978 - Defines minimal operating standards for OBD-II scan tools
- J1979 - Defines standards for diagnostic test modes
- J2012 - Defines standards trouble codes and definitions.
- J2178-1 - Defines standards for network message header formats and physical address assignments
- J2178-2 - Gives data parameter definitions
- J2178-3 - Defines standards for network message frame IDs for single byte headers
- J2178-4 - Defines standards for network messages with three byte headers*
- J2284-3 - Defines 500 kbit/s CAN Physical and Data link layer
- J2411 - Describes the GMLAN (single-wire CAN) protocol, used in newer GM vehicles. Often accessible on the OBD connector as PIN 1 on newer GM vehicles.
J1962 connector:
The SAE J1962 specification provides for two standardized hardware interfaces, called type A and type B. Both are female, 16-pin (2x8), D-shaped connectors, and both have a groove between the two rows of pins, but type B's groove is interrupted in the middle. This prevents the insertion of a type A male plug into a type B female socket while allowing a type B male plug to be inserted into a type A female socket.
The type A connector is used for vehicles that use 12V supply voltage, whereas type B is used for 24V vehicles and it is required to mark the front of the D-shaped area in blue color.
