What ison-board diagnostics

On-Board Diagnostics (OBD) is an electronic diagnostics program installed in cars to report trouble codes (DTCs) when something goes wrong. The system has come a long way since its first use in a Volkswagen in the late 1960s.

Today, anyone can use an OBD scanner to check the Check Engine light in their car. The scanner is connected to the OBD port under the dashboard, which was previously only accessible to auto mechanics.

While some devices only display codes, advanced scanners offer additional details and can even predict potential upcoming failures. This technology helps car owners diagnose problems before they worsen and prevent costly repairs in the future.
