For Wi-Fi adapters, you’ll connect to the adapter’s Wi-Fi network through your phone’s Wi-Fi settings. The app will then attempt to connect to the adapter.
Reading Diagnostic Trouble Codes DTCs
Once the app is connected to the adapter, you can begin reading codes. Most apps have a prominent “Read Codes” or “Check for Codes” button. Tap this button.
The app will then communicate with your car’s computer and retrieve any stored DTCs.
If your “check engine” light is on, you will likely see one or more codes listed. These codes typically look like “P0300” or “P0420.” The app will then usually provide a description of what each code means in plain language. For instance, “P0420 – Catalyst System Efficiency Below Threshold (Bank 1)” might be explained as “Your car’s catalytic converter is not working as efficiently as it should.”
Understanding Live Data
Beyond just reading codes, most smart phone diagnostic tools can also display live data from your car’s sensors. This is incredibly useful for diagnosing intermittent problems or monitoring your car’s performance.
You can see real-time information such as:
Engine RPM (Revolutions Per Minute): How fast the engine is turning.
Vehicle Speed: Your current speed on the road.
Engine Coolant Temperature: How hot or cold your engine is running.
Fuel System Status: Whether the fuel system is operating in open or closed loop.
Mass Air Flow (MAF) Sensor Readings: How much air is entering the engine.
By observing these readings while driving or under specific conditions, you can spot anomalies that might indicate a problem. For example, if your engine coolant temperature is unusually low or high, it could point to a faulty thermostat or cooling system issue.
Clearing Codes And Resetting Warnings
After identifying a problem and potentially fixing it, you can use the app to clear the DTCs. This will turn off your “check engine” light. However, it’s crucial to remember that clearing a code doesn’t fix the underlying issue.
If the problem persists, the code will likely return.
Some tools and apps also offer the ability to reset certain service lights, like oil change reminders. Always follow the app’s instructions carefully when clearing codes or resetting warnings. It’s a good practice to drive your car for a bit after clearing codes to ensure the light stays off.
If it comes back on, a further inspection is needed.
