Turn On the Ignition: Turn the ignition to the “on” position, but do not start the engine.
Follow the Scanner’s Instructions: Follow the instructions on the scanner’s screen to begin the diagnostic process.

3.3. Reading and Interpreting Diagnostic Trouble Codes (DTCs)

Diagnostic trouble codes (DTCs) are codes stored in the vehicle’s computer system when a problem is detected. These codes can help you identify the source of the issue.

Reading DTCs: Use the scanner to read the DTCs stored in the vehicle’s computer. The scanner will display the codes on the screen.
Interpreting DTCs: Each DTC corresponds to a specific problem. You can look up the meaning of the code in the scanner’s database or online.
Example: A common DTC is P0300, which indicates a random or multiple cylinder misfire.

3.4. Clearing DTCs: When and How

Clearing DTCs can be useful, but it’s important to do it properly.

When to Clear DTCs: Clear DTCs after you have identified and fixed the underlying problem. Clearing the codes without fixing the issue will only result in the codes returning.
How to Clear DTCs: Use the scanner to clear the DTCs. Follow the instructions on the scanner’s screen.
Important Note: Clearing DTCs will also reset the vehicle’s readiness monitors, which are used for emissions testing. You may need to drive the car for a while to allow the monitors to reset before taking it for an emissions test.
