What does it do?
An OBD fault code reader retrieves the code or codes that your car’s onboard diagnostic system generates when a problem is detected. If there is only one problem, only one code will be retrieved. If the problem is caused by the malfunctioning of multiple components or systems, the code reader will retrieve more than one codes.
How to use it?
To use an OBD fault code reader, you need to plug it into the data link connector that is located near the base of your steering wheel. Usually, you need to plug it in when the engine is off. When you turn on the ignition, the code reader will start performing its job.
How does it look?
This depends on the type of OBD fault code reader that you use. There are actually three general types of fault code reader that you can have.
