Car Check Engine Light Reader

A car check engine light reader is a device that can be used to read and clear the diagnostic trouble codes (DTCs) that are stored in a vehicle’s computer. These codes can help you to identify the cause of a check engine light and determine what repairs are needed.

How to Use a Car Check Engine Light Reader

Using a car check engine light reader is relatively simple. Here are the steps:

1. Connect the reader to your vehicle’s diagnostic port. This port is usually located under the dashboard, near the steering wheel.
2. Turn on the ignition, but do not start the engine.
3. Follow the instructions on the reader to read the DTCs.
4. Once you have read the DTCs, you can use them to look up the cause of the check engine light.

There are two main types of car check engine light readers:

• Basic readers: These readers can only read and clear DTCs. They are typically less expensive than advanced readers.
• Advanced readers: These readers can read and clear DTCs, as well as perform other functions, such as:
• Displaying live data from the vehicle’s computer
• Recording and playback data
• Performing actuator tests
