What is OBD and how is it used to monitor vehicle performance?

OBD stands for On-Board Diagnostics and is a computer system inside of a vehicle that tracks and regulates a car’s performance. The computer system collects information from the network of sensors inside the vehicle, which the system can then use to regulate car systems or alert the user to problems.

OBD has existed in various forms long before anyone ever uttered the words “infotainment” or “connected car.” It came about primarily because of two factors: The need to regulate emissions, and the mass adoption of electronic fuel injection by automakers beginning in the 1980s.

When did carb start requiring OBD in cars?

OBD vs. OBD II Several automakers introduced computer interfaces for their own cars before the 1990s, but the push to standardize didn’t begin until 1991, when the California Air Resources Board (CARB) mandated that all cars sold in California needed some form of OBD capability. However, CARB didn’t issue standards for the systems until 1994.

What does a trouble code on an OBD mean?

When a car’s sensors decide that something is amiss, they trigger a message known as a “trouble code,” which may manifest as a “check engine” light or another warning on the dashboard. OBD scanners can check these trouble codes to determine exactly what’s wrong, and clear them from the computer’s memory once the problem is fixed.
