Once connected, the MAXOBD app provides access to various diagnostic functions. Navigate through the app interface to utilize the following features:

6.1 Kernediagnostiske funktioner
- Læs koder: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's computer, indicating potential issues.
- Slet koder: Rydder DTC'er fra køretøjets computer og slukker Check Engine-lampen (MIL).
- Live datastrøm: Displays real-time data from various vehicle sensors, such as vehicle speed, RPM, engine coolant temperature, fuel pressure, calculated engine load, throttle position, intake manifold pressure, air intake temperature, timing advance, mass air flow, fuel level, barometric pressure, EVAP system vapor pressure, and fuel trim.
- I/M parathed: Kontrollerer status for emissionsrelaterede overvågningssystemer for at afgøre, om de er klar til en emissionstest.
- Frysestativ: Records a snapshot of vehicle operating conditions at the moment a fault code was set.
- O2-sensortest: Henter resultater fra O2-sensorovervågningstester for de senest gennemførte tests.
- Overvågning ombord: Henter resultater for overvågningstests af indbyggede diagnostiske systemer for specifikke komponenter/systemer.
- EVAP System (Mode$8): Starter en test af fordampningsemissionskontrolsystemet.
- Køretøjsoplysninger: Displays the vehicle identification number (VIN), calibration ID (CID), and calibration verification number (CVN).
- DTC-opslag: Giver definitioner for generiske og producentspecifikke diagnostiske fejlkoder.
- Dashboard: Customizable display of live data in a gauge format.
- OBD Diagnostic Report: Generates a comprehensive report of the vehicle's diagnostic status.


6.2 Batteritestning
The KW905 supports battery voltage testing to quickly display your car battery data.
- Navigate to the "Battery Testing" section in the MAXOBD app.
- The app will display current, maximum, and minimum battery voltage aflæsninger.
- Note: This function may require restarting the vehicle after it is turned off to ensure more accurate test results. Follow on-screen prompts.

7. Fejlfinding
- Enheden tænder ikke: Ensure the KW905 is firmly plugged into the vehicle's OBDII port and the vehicle's ignition is on (or engine running, depending on the test). Check the ON/OFF switch on the device.
- Problemer med Bluetooth-forbindelse: Make sure Bluetooth is enabled on your smartphone. Close and reopen the MAXOBD app. Try restarting both your phone and the KW905 device. Ensure no other Bluetooth devices are interfering.
- Appen registrerer ikke køretøjet: Verify that your vehicle is OBD2 compliant (1996 or newer, 12V gasoline/diesel/hybrid). Ensure the KW905 is securely connected to the OBDII port. Try turning the vehicle's ignition off and on again.
- "Vehicle does not support" message for certain functions (e.g., O2 Sensor Test): Some advanced functions or specific sensor data may not be supported by all vehicle makes, models, or years. This is normal and does not indicate a fault with the KW905.
- "Deep security Scan" and "Vehicle-Specific Data Stream" not available: These specific functions are explicitly noted as not currently supported on the KW905.
- Unøjagtige aflæsninger: Ensure the vehicle's engine is at operating temperature for accurate sensor readings. If readings seem consistently off, try recalibrating or restarting the app and device.
