9. Odpravljanje težav

9.1. Screen Without Display, No Power

1. Zaženite motor avtomobila.
2. Check if the OBD cable line is tightly connected. Try pulling down and re-inserting the OBD cable multiple times to ensure a secure connection.
3. Check if the product power switch is turned on.
4. If still no display, test the device in another car to determine if the issue is with the device or the car's OBD diagnostic interface. If the car's interface is faulty, repair it.

9.2. Only Shows Car Voltage, Automatic Power Off After 60 Seconds (P10/P10-PRO)

This indicates a compatibility issue. The P10/P10-PRO models are only compatible with cars that have an OBD2 or EU-OBD agreement (generally, cars produced after 2004 for US automakers, and after 2008 for European/Asian automakers). This product does not support JOBD and OBDI protocols. If your car falls outside these specifications, it is recommended to test with another compatible car.

9.3. Inaccurate Speed

1. First, ensure the speed unit (KM/H or MPH) is correctly set in the device settings.
2. If the speed is still inaccurate, enter the setting menu, navigate to 'Speed Adjust', and adjust the value to match your car's dashboard speed. For example, if your dashboard shows 100 and the device shows 101, adjust the default value to 106%.

9.4. Inaccurate Fuel Consumption

Check your car's engine displacement and set the device's 'Engine Size' parameter accordingly (e.g., if your car is 2.0L, set the device to 2.0L). While fuel consumption can be adjusted, it is generally not recommended as the data is read directly from the car's ECU.

9.5. RPM Alarm

If the RPM alarm is not functioning as expected, refer to the settings menu to adjust the default alarm value (default is 6000 r/min).

9.6. Over Speed Alarm

If the over speed alarm is not functioning as expected, refer to the settings menu to adjust the default alarm value (default is 150 KM/H).

9.7. Device Cannot Auto Power Off

1. Speed Display After Vehicle Off: If the device continues to display speed after the vehicle is turned off, switch to the 'Speed Offset' setting and adjust its value to match the speed displayed by the device (e.g., if it shows 5KM/H, set the offset to 5).
2. RPM Display After Vehicle Off: If the device continues to display RPM after the vehicle is turned off, switch to the 'Sleep Voltage' setting and adjust the value to 13.2V.

9.8. Auto Start and Stop Cars

For cars with auto start/stop functionality, change the 'Power Off Time' setting to 180-240 seconds to prevent premature shutdown.

9.9. Wrong Operation Leads to Crashes

If the device crashes due to incorrect operation, perform a 'Factory Set' reset.

9.10. Car Dashboard Fault Code Bright (P10/P10-PRO)

Universal OBD devices support multiple communication modes, but each car typically uses only one. If your car's dashboard shows a fault code after connecting the HUD, you may need to adjust the OBD communication protocol by pulling up unneeded pins from the OBD cable using pliers. The device will display the protocol when the vehicle turns on, then unplug and re-plug the OBD cable.

OBD Communication Protocol Examples:

• ISO15765 CAN Bus: Keep pins 4, 5, 6, 14, 16. Pull up other pins.
• ISO14230 KWP2000: Keep pins 4, 5, 7, 16. Pull up other pins.
• ISO 9141-2: Keep pins 4, 5, 7, 15, 16. Pull up other pins.

10. Tehnične specifikacije

11. Uporabniški nasveti

• Previdno preverite združljivost: Pred nakupomasing, especially for OBD models, verify your car's year and protocol. Older cars (pre-2004 US, pre-2008 EU/Asian) and certain vehicle types (electric, diesel, hybrid, pickup, passenger cars) may not be compatible with OBD models. If unsure, contact the seller with your car's make, model, year, and agreement type.
• GPS Model for Universal Use: If you need a HUD for any car, including those with compatibility issues for OBD models, the Y03 GPS model is a reliable universal option.
• Varna napeljava kablov: When installing the OBD cable, take time to route it neatly and securely along the car's interior to prevent it from interfering with pedals or other controls.
• Adjust Brightness for Optimal View: While automatic brightness is convenient, manually adjust it if you find the display too dim or too bright in specific lighting conditions.
• Utilize Diagnostic Features: For OBD models, regularly check for and clear fault codes to maintain your vehicle's health and prevent minor issues from escalating.
