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.
FAQs about On-Board Diagnostics
What is the Check Engine light?
The Check Engine light is a warning light that comes on when something is not quite right with your car’s engine. It does not necessarily mean that the engine is about to fail, but it is a sign that you should have your car checked by a professional to prevent any potential issues.
What are trouble codes (DTCs)?
Trouble codes, also known as Diagnostic Trouble Codes (DTCs), are codes that indicate a problem with your car. These codes can be deciphered with an OBD scanner to determine what the problem is and how it can be resolved.
How often should I use an OBD scanner?
It is recommended to use an OBD scanner at least once a year to check for any potential issues with your car. If you notice any warning lights or changes in performance, you should have a diagnostic check done as soon as possible.
In conclusion, On-Board Diagnostics (OBD) is a helpful technology that can help car owners diagnose potential car issues before they become major problems. By using an OBD scanner, anyone can quickly and easily check their car’s Check Engine light and take steps to resolve any issues.
