DTCs are codes that indicate specific issues with your vehicle. The OBDII app will display these codes along with a brief description of the problem.

Access the DTC Menu: In the app, navigate to the section for reading trouble codes.
Read the Codes: The app will scan your vehicle’s system and display any stored DTCs.
Interpret the Codes: Each DTC consists of a letter followed by four numbers. The letter indicates the system affected:
- P: Powertrain (engine, transmission)
- B: Body (interior, exterior)
- C: Chassis (brakes, suspension)
- U: Network (communication)
The numbers provide more specific information about the issue. For example, P0300 indicates a random/multiple cylinder misfire.
Clear the Codes: After addressing the issue, you can clear the DTCs using the app. Be cautious when clearing codes, as it can erase important diagnostic information.

4.2 Understanding Live Data

Live data provides real-time information about your vehicle’s performance. Common parameters include:

Fuel Trim: Adjustments made to the fuel mixture by the engine control unit (ECU).
Oxygen Sensor Readings: Voltage readings from the oxygen sensors in the exhaust system.
Mass Air Flow (MAF): Rate of air flowing into the engine.
Throttle Position: Percentage of throttle opening.
Calculated Load Value: Percentage of engine load based on current conditions.

4.3 Using Freeze Frame Data

Freeze frame data captures a snapshot of vehicle parameters at the moment a DTC was triggered. This information can be invaluable for diagnosing intermittent issues.

Access Freeze Frame Data: In the OBDII app, navigate to the freeze frame data section.
Review the Data: The app will display the parameters recorded at the time the DTC was set.
Analyze the Data: Look for any unusual readings or patterns that might indicate the cause of the problem. For example, if a misfire code (P0300) was triggered, check the engine RPM, load value, and oxygen sensor readings in the freeze frame data.

4.4 Creating Custom Dashboards

Most OBDII apps allow you to create custom dashboards to display the data that’s most important to you.

Access Dashboard Settings: In the app, navigate to the dashboard settings or customization menu.
Add Gauges: Select the parameters you want to monitor and add them to the dashboard as gauges or graphs.
