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.
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 .
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).

The problems reflect bugs that were present in ELM's version 1.4 microcode; those making the clones may continue to sell the old version. Although these copies may contain the ELM327 v1.4 code, they may falsely report the version number as the current version provided by the genuine ELM327, and in some cases report an as-yet non-existent ...
This can be information of all kinds and of different lengths such as Partnumber or the software version. Dynamic values such as the current state of the sensor can be queried. Each value is associated to a Data Identifier (DID) between 0 and 65535; for example, the VIN DID is 61840d (0xF190). Normal CAN signals are meant for information that ...

This includes clearing the stored pending/confirmed DTCs and Freeze Frame data. • Mode $0A lists emission-related "permanent" diagnostic trouble codes stored. As per CARB, any diagnostic trouble codes that is commanding MIL on and stored into non-volatile memory shall be logged as a permanent fault code.
