Connection Method of Ignition-switched (ON) Line
This is required in certain cases:
- After turning on the menu "SLEEP RPM NOT CHANGE" function, to keep the product working when the engine auto-off.
- The product wake-up or sleep synchronously with Ignition-switched.
- After starting the vehicle, the product cannot wake-up automatically for a long time.
- Electric vehicles, old models without OBD data, or when "TURN OFF OBD DATA" is turned off. Only G meter, gyroscope meter, and GPS functions are needed.
Installation Steps:
- Find and pull out the fuse according to the fuse instructions.
- Peel the detection line and wrap the leakage outlet head around the fuse, and then screw it for several turns to lock it.
- Insert the fuse back, turn on the vehicle power supply and test whether the product works normally or not.
Ignition ON switch fuses examples: Cigarette lighter, wiper, air conditioner, etc.
Item Setting & Pop-up Functions
Item setting:
The detailed name of the meter is prompted here.
Setting steps:
- Navigate to "DISPLAY SETUP->ITEM SETUP" to enter the modification interface.
- Switch selection by pressing the menu button several times.
- Switch item data by short/long pressing the up or down button. (Detailed explanation will be in the pop-up window).
- End the setting by pressing the return button.
Pop-up functions:
Example 1 - Turbo warning
Example 2 - Water T. warm-up
Several situations that meet the pop-up prompt:

- The water temperature in warm-up mode is too low and there is no water temperature data display in the interface.
- Door opening (special system).
- Reading OBD protocol (unless "TURN OFF OBD DATA" is turned on and only GPS data is used).
Note: If the above conditions are met at the same time, it will be displayed circularly.

Common Malfunction Analysis
| Issue | Possible Causes & Solutions |
|---|---|
| Unable to power on or read data | 1. Loose connection of OBD power port. 2. Loose connection Instrument power port. 3. OBD port fuse might be fused. 4. The engine is not started, or the model is too old. 5. If it's a special model, choose "SYSTEM SETUP->CHOOSE SYSTEM" menu switch to the special system. |
| Random change of display data, acceleration of the vehicle is worse than that before installation | 1. Enter "SYSTEM SETUP->PID TIME LOOP" and increase the time until it is stable. 2. Enter "ABOUT PRODUCT->ISO WORK MODE" and set it to normal mode. |
| Unable to use auto dimmer control mode | 1. Enter "DISPLAY SETUP->DIMMER" function menu to set to auto. 2. Unknown object covering the dimmer sensor. 3. Dimmer sensor broken. |
| No beeper sound for alarm | 1. Enter "SYSTEM SETUP->BUZZER SOUND" menu to turn on. 2. Buzzer broken. |
| Unable to clear or read DTC(s) | 1. Operate after engine off. 2. Special DTC(s), please use professional equipment. |
| Inaccurate time or time zone difference | 1. No GPS signal or weak signal. 2. Enter "SYSTEM SETUP->GPS TIME" to modify the time zone. |
| The burglar alarm is activated after locking the door | Because the product is still working and the OBD protocol is still connected, resulting in a vehicle false alarm. Please check steps 4 and 5 of page 4. |
| Inaccurate turbo data | Turn on the Ignition-switched to power on the air conditioner, press any button to wake-up the product, and refer to Page 6 to calibrate the turbo data to 0.00 (atmospheric pressure value). |
Other Instructions
Fuel consumption specification
- Fuel consumption is calculated based on data from airflow or turbo/intake pressure. If the user's vehicle does not possess one of the data listed above, the product won't be able to get the fuel consumption data.
- The fuel consumption conversion formula can be divided to fit gasoline or diesel cars. Please check the engine type and enter “SYSTEM SETUP->FUEL TYPE” to select the corresponding type.
Note: Fuel consumption's calculated result might be slightly off with the actual number. Please calibrate based on vehicle's condition.
Screen-off dormancy special settings
If the vehicle has an auto off function or is a hybrid, and the user wants the product to work when the engine auto off, both functions of "SLEEP RPM NOT CHANGE" and "SLEEP WHEN AUTO OFF" must be turned off, or the reference (Page 4) is connected to the ON power detection line to control the instrument on and off.
PID Reading cycle
The delay of reading ECU data varies according to different vehicle models. The shorter the reading time, the faster the data response. The time delay of reading ECU data on different vehicle types is different; the user can set "PID TIME LOOP" time based on the car's ability.
Manual wake-up
- When the product is in sleep and the user does not want to start the engine, the user can press any function button to wake-up the product.
- If no function button is pressed after wake-up, the product will automatically go to sleep again after one minute.
Note: Some vehicles' DTC(s) cannot be cleared while running; please wake-up the product to clear the DTC(s).
