Have you ever noticed a Check Engine light on your car’s dashboard light up? Or, do you know what the OBD port under your car’s dashboard is for? The OBD port is a crucial component of modern cars that enables electronic diagnostics on the car through a program called On-Board Diagnostics (OBD).
The OBD system dates back to the late 1960s when the first diagnostic computer was used in a Volkswagen, and today, anyone can use an OBD scanner to check the Check Engine light in a car simply by plugging it into the OBD port. Previously only accessible to auto mechanics, these scanners are now widely available and affordable for car owners too.
Using an OBD scanner helps you read trouble codes or DTCs, which report any issues observed within the system. While some scanners only display codes, others provide additional details and even forecast system failures. Chances are you can easily diagnose the problem yourself by reading the code and looking it up online, saving you a costly visit to the mechanic.
