OBD-II is an improvement over OBD-I hinein 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. There is a pin rein the connector that provides power for the scan Dienstprogramm from the vehicle battery, which eliminates the need to connect a scan Dienstprogramm to a power source separately. However, some technicians might tonlos connect the scan tool to an auxiliary power source to protect data rein the unusual Fest that a vehicle experiences a loss of electrical power due to a malfunction.

This is used by service technicians after a vehicle repair, and after clearing diagnostic information to see test results after a single driving cycle to determine if the repair has fixed the Harte nuss.
There have been reports of thieves using specialist OBD reprogramming devices to enable them to steal cars without the use of a key.[35] The primary causes of this vulnerability lie rein the tendency for vehicle manufacturers to extend the bus for purposes other than those for which it was designed, and the lack of authentication and authorization hinein the OBD specifications, which instead rely largely on security through obscurity.

BAFX Bluetooth adapter is one of the clone adapters. We bought this adapter for testing and at least ur unit seems to work ok.
Modern OBD implementations use a standardized digital communications port to provide Wahrhaft-time data hinein addition to a standardized series of diagnostic Sorge codes (DTCs) which allow one to rapidly identify and remedy malfunctions within the vehicle.
