What the Onboard Diagnostics System Is and How It Works
So, the Onboard Diagnostics system, often called OBD, is your vehicle’s built-in monitoring computer. Because sensors track engine performance, emissions, and other systems, the computer receives constant data. Therefore, when a sensor detects a problem, the system stores a trouble code and may trigger the check engine light. Then, technicians use a scan tool to read the codes while you continue driving around Salem.

-
Because it detects issues early, major repairs often get avoided.
