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 has the groove interrupted in the middle, so it isn't possible to plug a type A male connector into a type B socket. It is possible, however, to mate a type B male plug in 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.

Revision as of 11:21, 18 December 2025

The OBD-II data link connector (post-1996 light duty vehicles) is a standardized diagnostic connection for communicating Parameter IDs (PIDs) from a vehicle to a diagnostic tool.

Light Duty (passenger cars and trucks) OBD-II Connectors (Type A and B)

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. Type B has an interrupted groove in the middle, so it isn't possible to plug a type A male connector into a type B socket. It is possible, however, to mate a type B male plug to a type A female socket. The type A connector is used for vehicles that use 12V system, whereas type B is used for 24V vehicles and it is required to mark the front of the D-shaped area in blue color.

Type A (12V) vs Type B (24V)

OBD-II Connector Parts

OBD-II compatible connectors are available from a variety of manufacturers:

OBD-II Pinout

Pin # Function / Description
1 Manufacturer-specific
2 SAE J1850 Bus+ (VPW/PWM)
3 Manufacturer-specific
4 Chassis ground
5 Signal ground
6 CAN High (ISO 15765‑4)
7 K‑Line (ISO 9141‑2 / ISO 14230‑4 KWP2000)
8 Manufacturer-specific
9 Manufacturer-specific
10 SAE J1850 Bus– (PWM only)
11 Manufacturer-specific
12 Manufacturer-specific
13 Manufacturer-specific
14 CAN Low (ISO 15765‑4)
15 L‑Line (ISO 9141‑2 / older KWP)
16 Battery power (unswitched +12V)

PIDs / Codes

SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections. Manufacturers also define additional PIDs specific to their vehicles. Though not mandated, many motorcycles also support OBD-II PIDs.

Heavy Duty OBD-II Connectors

Heavy duty vehicles (greater than 14,000 lb or 6,400 kg) made after 2010, for sale in the US are allowed to support OBD-II diagnostics through SAE standard J1939-13 (a round diagnostic connector) according to CARB in title 13 CCR 1971.1. Some heavy duty trucks in North America, however, use the SAE J1962 OBD-II diagnostic connector that is common with light duty vehicles, notably Mack and Volvo Trucks.
