![]() It is also not OEM-specific, although some manufacturers may use OEM (Original Equipment Manufacturer) codes for systems that are specifically unique to their vehicles.Īll vehicles manufactured after 1996 in the United States are required to have an OBD2 system. OBD2 scan tools are also a step up from initial OBD1 scanners that are OEM-specific and scan codes in vehicles made during 1988-1996. Modern OBD tools on the other hand use a standardized digital communication port in order to provide real-time data that can be used to not just detect an overall problem, but provide real-time data and diagnostic trouble codes (DTCs), which makes finding or identifying a problem and being able to fix it possible. ![]() However, no information would be provided to the nature of the problem. Since then, the amount of available diagnostic information on those devices has significantly increased.Įarly OBD illuminated a malfunctioning indicator light (MIL), otherwise known as idiot light, if there was a problem detected. In the early 1980s, the first on-board vehicle computers, which could be considered to be the primitive form of today’s OBD scanners, were introduced. OBD scanning tools allow vehicle owners or mechanics to access the status of vehicle systems and diagnostic codes. OBD stands for “On-Board Diagnostics,” and the number 2 refers to the fact that this is the second generation of onboard diagnostic systems used in vehicles. ![]() OBD2 diagnostic scan tools are electronic devices that connect to a car’s onboard computer to read and diagnose engine issues. Our team has researched and tested OBD scanners across the board to narrow down the list of scan tools to just three of the best professional automotive diagnostic scanners in terms of functionality, quality, and overall value. If you’re looking for fully capable professional car diagnostic tools, and the best professional OBD2 scanner, you came to the right place.
