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.

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. 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.
