7. Research Codes: Use the scanner’s built-in code definitions or online resources to research the meaning of each DTC.
8. Clear Codes (Optional): If you want to clear the codes, select the “Clear Codes” option on the scanner. Be aware that clearing codes will erase any stored diagnostic information.
9. Test Drive: After clearing the codes (if applicable), take the vehicle for a test drive to see if the check engine light comes back on.
10. Further Diagnosis: If the check engine light comes back on, perform further diagnosis based on the DTCs and your research.

5.2. Interpreting Diagnostic Trouble Codes (DTCs)

DTCs are five-character codes that provide information about potential issues with your vehicle. The first character indicates the system that is affected:

• P: Powertrain (engine, transmission, etc.)
• B: Body (airbags, seatbelts, etc.)
• C: Chassis (ABS, brakes, suspension, etc.)
• U: Network (communication systems)

The second character indicates whether the code is generic (0) or manufacturer-specific (1). The remaining three characters provide more specific information about the fault.

5.3. Understanding Live Data Streams

Live data streams provide real-time information about various parameters, such as:

• Engine RPM
• Coolant Temperature
• Oxygen Sensor Readings
• Fuel Trim
• Ignition Timing

By monitoring these parameters, you can gain insights into how different components are functioning and identify potential issues.

5.4. Utilizing Freeze Frame Data

Freeze frame data captures a snapshot of sensor values at the moment a DTC is triggered. This information can help you pinpoint the conditions that led to the fault.

5.5. Safety Precautions and Best Practices

• Always read and follow the instructions in the car scanner’s user manual.
• Do not attempt to diagnose or repair your vehicle if you are not qualified to do so.
• Wear appropriate safety gear, such as gloves and eye protection, when working on your vehicle.
• Work in a well-ventilated area.
