OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. 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 .
OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each.

Request Download Downloading new software or other data into the control unit is introduced using the "Request Download". Here, the location and size of the data is specified. In turn, the tester specifies how large the data packets can be. 0x35 0x75 Request Upload The service "request upload" is almost identical to the service "Request Download".
For example, in the 2010s, as federal and state judges struck down same-sex marriage bans across the country, many judges stayed the rulings during the appeals process. Although a state's ban was struck down, such as that of Louisiana , the stay prevented implementation of their ruling pending a higher court decision and so prevented same-sex ...

The OBD-II DLC (post-1996 vehicles) is usually located under the instrument panel on the driver side, though there are several exceptions. 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.
Many later 8192 baud vehicles, for example, had airbag control, ABS, and even climate control units sending data on the same serial bus. In both versions, ALDL data is sent in a format unique to the model of ECU in the vehicle with little standardization between models, so a proper definition of the data is required to interpret it.
