| The specific data of the gear/door/window/seat belt/light/etc. vehicle data state is based on the vehicle data support situation. | |
| Read vehicle fault | The terminal recognizes the vehicle fault information, and when the vehicle fault status changes, it reports to the platform. |
| Clear vehicle fault | Clear vehicle faults by issuing instructions on the platform. |
| Bus control | Through CAN or K/L line bus control window raising, car search, unlocking and locking, blasting, folding rearview mirror, etc. |
|
Remote management function |
|
| Remote upgrade | The terminal software can be upgraded remotely through the GPRS network and through the FTP server. |
| Remote restart | Send instructions to restart the device through the data channel; |
| Remote query | The platform uses GPRS to remotely query terminal information, vehicle type, GPRS communication parameters, heartbeat parameters, GPS/CAN return parameters, SIM card information, GPS information, CAN data stream, various alarm parameters for current faults, and parameters for rapid acceleration, rapid deceleration, and sharp cornering. . |
| Remote setting | The platform uses GPRS to remotely set terminal information, vehicle type, GPRS communication parameters, heartbeat parameters, GPS/CAN return parameters, clear vehicle faults, control restart, restore factory settings, clear blind zone data, various alarm parameters, rapid acceleration and rapid deceleration Turning parameters. |
