What’s The Difference Between OBD And OBD2?
In mechanics, OBD is a technical term that stands for “onboard diagnostics.” It refers to the high-tech system that diagnoses and reports engine problems in the vehicle. The system will alert the driver of issues and store the code related to the issue, which tells the scan tool of the technician what’s going on with the engine. As a driver, you’ll see it at work when the “Check Engine Light” or “Service Engine Soon” light turns on. Of course, this only works when the driver pays attention to those pesky lights and takes their vehicle in for repairs!
Since the 1990s, onboard diagnostics has changed from the OBD system to OBD2. This was a big advancement for mechanics, and it has made the diagnosis of engine problems easier and more reliable.
