What is the fault when the Great Wall VV7 displays T-BOX?

[KathrynAnn]

T-BOX fault refers to a problem with the vehicle's T-BOX in the telematics system. Structure of T-BOX: It consists of a dual-core processor with STM32F103CBT6 and STM32F105RBT6 as the main controllers. In addition, GPRS, GPS, a six-axis G-Sensor, and a vibration sensor are called by the main controller, along with two 12V outputs. The vehicle T-BOX communicates with the host via CAN bus, enabling the transmission of commands and information, including vehicle status information, adjustment commands, etc. Functions of T-BOX: The T-BOX has many functions, the most common being remote query, remote control, and security services. Remote query refers to the ability to check the vehicle's status at that time through a mobile app, such as whether the doors and windows are closed, fuel level, etc. Remote control refers to the ability to adjust and activate the air conditioning, set the temperature, control door and window switches, honk the horn, flash lights, start the engine, and perform real-time vehicle positioning, among other functions, via a mobile app. Security service functions include roadside emergency assistance, remote automatic upload of abnormal vehicle information, and automatic alarm for vehicle movement.
