OBD smart digital device installation

1. Know your vehicle brand, the OBD smart digital device work for cars with the OBDII agreement or EU OBD agreement. Open the engine hood and find the sticker below it (see the below picture 1), if it has words like OBDII CERTIFIED, then it can be installed.
2. Find out the 16 pin diagnostic link (see the below picture 2) of the vehicle and connect it well with OBDII connecting line.
3. Connect the Suction cup mount with the unit.

Technical Parameters:
Environment temperature: -40c- + 80c
Atmospheric pressure 86-106KPa
Relative Humidity: 10% -95%
environmental noise <= 60dB (A)
Alarm sound level: 》=30dB (A)
Working voltage: 9V ~ 16Vdc (12Vdc / 400mA)
Product size: 83 x 60 x 15mm
Product Weight: 50 g

Troubleshooting

1. The screen without any display, and no power
   Start the car engine;check if the OBD cable line is tight;please pull down the OBD cables more times to ensure; check if the product power switch turns on. If still no display, please change another car to test, analyze whether the car OBD diagnostic interface is good, if it is not good, please repair it and try again.

2. Only shows the car voltage and be automatic power off after 60 seconds when the device is with power
   this product just available for cars with OBD2 agreement and EU-OBD agreement(European region: produced after 2003 years, another region: produced after 2007 years)
   This Products donnot support JOBD and OBDI and are recommended test for another car.

3. Inaccurate Speed
   a.First check the speed unit is correct or not, the speed unit includes KM/H and MPH, please refer to the setting to switch the unit.
   b.When the product is power on, long press in the button to enter into the menu option, and right push once switch to setting,then short press in the button to the menu and right push the button switch to the speed adjustment option.(if the dashboard shows 100,and the device shows the 101, change the default value at 106%)

4. Inaccurate Fuel consumption
   Check your car displacement,and set the device same as your car(if your car is 2.0L, then change the device value at 2.0L). The fuel consumption can be adjusted,but we don’t suggest changing it , because all the data are read from the car ECU directly.

5. RPM Alarm
   Default alarm is 6000, please refer to the setting to change.

6. Over speed alarm
   Default alarm is 150KM/H,please refer to the setting to change the value.

7. The device cannot auto power off
   A.After vehicle turns off,the device still display the speed, switch the setting to Speed Offset, and adjust the value same as the device speed.(if the device shows 5KM/H after the vehicle turns off,then change the speed offset at 5KM/H)
   B.After the vehicle turns off,the device still displays the RPM, switch the setting to sleep voltage and make the value at 13.2V

8. Auto start and stop cars
   Change the Power off time to 180s

9. The wrong operation lead to crashes
   Do a factory set

10. Why it will cause the car dashboard fault code bright?
    As Universal OBD device supports multiple communication modes, and generally each car only supports one kind of communication protocol, according to the protocol to pull up the unneeded pins by the pliers.(when the vehicle turns on, unplug and OBD cable and re-plug again,it will display the protocol)

11. Communication protocol ISO15765 CAN Bus,keep the 4/5/6/14/16 pins,and pull up the other pins,as the below picture:

12. Communication protocol ISO14230 KWP2000,keep the 4/5/7/16 pins,and pull up the other pins,as the below picture:

13. Communication protocol ISO 9141-2,keep the 4/5/7/15/16 pins,and pull up the other pins,as the below picture
