| The terminal has been unable to connect to the background server after the first installation, and the background display is not online | Whether the main power wiring is correct, take care not to connect it to the car’s internal control line; |
| Whether the SIM card is correctly installed; | |
| Check parameter settings; | |
| Check whether the identity information of the terminal is correctly entered on the platform; | |
| Whether the ACC line is connected, insert the car key and connect to ACC ON; | |
| Check whether it has been located. If it is not located, go to the outdoor open area for the first time; | |

Terminal shows offline status in background |
Dial the SIM card number of the device to see if you can hear the phone connection; |
| Whether the SIM card is in arrears and whether the GPRS data service is cancelled; | |
| Whether the vehicle has no GSM network signal coverage in the basement; | |
| Observe whether the offline area is offline or all offline, and determine whether it is a network problem of the operator; | |

The terminal is not positioned for a long time or the positioning deviation is large |
Whether the front installation is correct, facing up to the sky; |
| Whether there is a substance (such as metal) that absorbs electromagnetic waves above the front installation location, and whether there is an explosion-proof thermal insulation film on the glass above the location (the higher metal content in the film will absorb high-frequency electromagnetic waves); | |

| When the positioning is inaccurate, please pay attention to check whether the LED is positioned. If it is not positioned, it is the historical position point or LBS position. When the positioning indicator is always on and inaccurate, please check whether the turnover environment has a unidirectional or Y-plane signal reflecting the building. | |
